Enumerant Descriptions
[kotlinc] [kotlinc] [kotlinc] The #SESSION_STATE_UNKNOWN state must not be returned by the runtime, and is only defined to avoid 0 being a valid state. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_IDLE state indicates that the runtime considers the session is idle. Applications in this state should minimize resource consumption but continue to call #PollEvent() at some reasonable cadence. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_READY state indicates that the runtime desires the application to prepare rendering resources, begin its session and synchronize its frame loop with the runtime. The application does this by successfully calling #BeginSession() and then running its frame loop by calling #WaitFrame(), #BeginFrame() and #EndFrame() in a loop. If the runtime wishes to return the session to the #SESSION_STATE_IDLE state, it must wait until the application calls #BeginSession(). After returning from the #BeginSession() call, the runtime may then immediately transition forward through the #SESSION_STATE_SYNCHRONIZED state to the #SESSION_STATE_STOPPING state, to request that the application end this session. If the system supports a user engagement sensor and runtime is in #SESSION_STATE_IDLE state, the runtime should not transition to the #SESSION_STATE_READY state until the user starts engaging with the device. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_SYNCHRONIZED state indicates that the application has synchronized its frame loop with the runtime, but its frames are not visible to the user. The application should continue running its frame loop by calling #WaitFrame(), #BeginFrame() and #EndFrame(), although it should avoid heavy GPU work so that other visible applications can take CPU and GPU precedence. The application can save resources here by skipping rendering and not submitting any composition layers until #WaitFrame() returns an ##XrFrameState with {@code shouldRender} set to true. A runtime may use this frame synchronization to facilitate seamless switching from a previous XR application to this application on a frame boundary. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_VISIBLE state indicates that the application has synchronized its frame loop with the runtime, and the session?s frames will be visible to the user, but the session is not eligible to receive XR input. An application may be visible but not have focus, for example when the runtime is composing a modal pop-up on top of the application?s rendered frames. The application should continue running its frame loop, rendering and submitting its composition layers, although it may wish to pause its experience, as users cannot interact with the application at this time. It is important for applications to continue rendering when visible, even when they do not have focus, so the user continues to see something reasonable underneath modal pop-ups. Runtimes should make input actions inactive while the application is unfocused, and applications should react to an inactive input action by skipping rendering of that action?s input avatar (depictions of hands or other tracked objects controlled by the user). [kotlinc] [kotlinc] Receiving the #SESSION_STATE_FOCUSED state indicates that the application has synchronized its frame loop with the runtime, the session?s frames will be visible to the user, and the session is eligible to receive XR input. The runtime should only give one session XR input focus at any given time. The application should be running its frame loop, rendering and submitting composition layers, including input avatars (depictions of hands or other tracked objects controlled by the user) for any input actions that are active. The runtime should avoid rendering its own input avatars when an application is focused, unless input from a given source is being captured by the runtime at the moment. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_STOPPING state indicates that the runtime has determined that the application should halt its rendering loop. Applications should exit their rendering loop and call #EndSession() when in this state. A possible reason for this would be to minimize contention between multiple applications. If the system supports a user engagement sensor and the session is running, the runtime should transition to the #SESSION_STATE_STOPPING state when the user stops engaging with the device. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_EXITING state indicates the runtime wishes the application to terminate its XR experience, typically due to a user request via a runtime user interface. Applications should gracefully end their process when in this state if they do not have a non-XR user experience. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_LOSS_PENDING state indicates the runtime is no longer able to operate with the current session, for example due to the loss of a display hardware connection. An application should call #DestroySession() and may end its process or decide to poll #GetSystem() at some reasonable cadence to get a new {@code XrSystemId}, and re-initialize all graphics resources related to the new system, and then create a new session using #CreateSession(). After the event is queued, subsequent calls to functions that accept {@code XrSession} parameters must no longer return any success code other than #SESSION_LOSS_PENDING for the given {@code XrSession} handle. The #SESSION_LOSS_PENDING success result is returned for an unspecified grace period of time, and the functions that return it simulate success in their behavior. If the runtime has no reasonable way to successfully complete a given function (e.g. #CreateSwapchain()) when a lost session is pending, or if the runtime is not able to provide the application a grace period, the runtime may return #ERROR_SESSION_LOST. Thereafter, functions which accept {@code XrSession} parameters for the lost session may return #ERROR_SESSION_LOST to indicate that the function failed and the given session was lost. The {@code XrSession} handle and child handles are henceforth unusable and should be destroyed by the application in order to immediately free up resources associated with those handles.

[kotlinc] [kotlinc]
C Specification
[kotlinc] Function pointers for all OpenXR functions can be obtained with the function #GetInstanceProcAddr(). [kotlinc] [kotlinc] 

  [kotlinc] ?XrResult xrGetInstanceProcAddr(
  [kotlinc] ?    XrInstance                                  instance,

[kotlinc] [kotlinc]
Description
[kotlinc] #GetInstanceProcAddr() itself is obtained in a platform- and loader- specific manner. Typically, the loader library will export this function as a function symbol, so applications can link against the loader library, or load it dynamically and look up the symbol using platform-specific APIs. Loaders must export function symbols for all core OpenXR functions. Because of this, applications that use only the core OpenXR functions have no need to use #GetInstanceProcAddr(). [kotlinc] [kotlinc] Because an application can call #GetInstanceProcAddr() before creating an instance, #GetInstanceProcAddr() returns a valid function pointer when the {@code instance} parameter is #NULL_HANDLE and the {@code name} parameter is one of the following strings: [kotlinc] [kotlinc]
No Instance Required
[kotlinc] [kotlinc] [kotlinc] #GetInstanceProcAddr() must return #ERROR_HANDLE_INVALID if {@code name} is not one of the above strings and {@code instance} is #NULL_HANDLE. #GetInstanceProcAddr() may return #ERROR_HANDLE_INVALID if {@code name} is not one of the above strings and {@code instance} is invalid but not #NULL_HANDLE. [kotlinc] [kotlinc] #GetInstanceProcAddr() must return #ERROR_FUNCTION_UNSUPPORTED if {@code instance} is a valid instance and the string specified in {@code name} is not the name of an OpenXR core or enabled extension function. [kotlinc] [kotlinc] If {@code name} is the name of an extension function, then the result returned by #GetInstanceProcAddr() will depend upon how the {@code instance} was created. If {@code instance} was created with the related extension?s name appearing in the ##XrInstanceCreateInfo{@code ::enabledExtensionNames} array, then #GetInstanceProcAddr() returns a valid function pointer. If the related extension?s name did not appear in the ##XrInstanceCreateInfo{@code ::enabledExtensionNames} array during the creation of {@code instance}, then #GetInstanceProcAddr() returns #ERROR_FUNCTION_UNSUPPORTED. Because of this, function pointers returned by #GetInstanceProcAddr() using one {@code XrInstance} may not be valid when used with objects related to a different {@code XrInstance}. [kotlinc] [kotlinc] The returned function pointer is of type {@code PFN_xrVoidFunction}, and must be cast to the type of the function being queried. [kotlinc] [kotlinc] The table below defines the various use cases for #GetInstanceProcAddr() and return value (?{@code fp}? is ?{@code function pointer}?) for each case. [kotlinc] [kotlinc]

Description

[kotlinc] [kotlinc]
Description
[kotlinc] For a {@code time} in the past, the runtime should locate the spaces based on the runtime?s most accurate current understanding of how the world was at that historical time. [kotlinc] [kotlinc] For a {@code time} in the future, the runtime should locate the spaces based on the runtime?s most up-to-date prediction of how the world will be at that future time. [kotlinc] [kotlinc] The minimum valid range of values for {@code time} are described in prediction-time-limits. For values of {@code time} outside this range, #LocateSpace() may return a location with no position and #SPACE_LOCATION_POSITION_VALID_BIT unset. [kotlinc] [kotlinc] Some devices improve their understanding of the world as the device is used. The location returned by #LocateSpace() for a given {@code space}, {@code baseSpace} and {@code time} may change over time, even for spaces that track static objects, as one or both spaces adjust their origins. [kotlinc] [kotlinc] During tracking loss of {@code space} relative to {@code baseSpace}, runtimes should continue to provide inferred or last-known {@code position} and {@code orientation} values. These inferred poses can, for example, be based on neck model updates, inertial dead reckoning, or a last-known position, so long as it is still reasonable for the application to use that pose. While a runtime is providing position data, it must continue to set #SPACE_LOCATION_POSITION_VALID_BIT but it can clear #SPACE_LOCATION_POSITION_TRACKED_BIT to indicate that the position is inferred or last-known in this way. [kotlinc] [kotlinc] If the runtime has not yet observed even a last-known pose for how to locate {@code space} in {@code baseSpace} (e.g. one space is an action space bound to a motion controller that has not yet been detected, or the two spaces are in disconnected fragments of the runtime?s tracked volume), the runtime should return a location with no position and #SPACE_LOCATION_POSITION_VALID_BIT unset. [kotlinc] [kotlinc] The runtime must return a location with both #SPACE_LOCATION_POSITION_VALID_BIT and #SPACE_LOCATION_POSITION_TRACKED_BIT set when locating {@code space} and {@code baseSpace} if both spaces were created relative to the same entity (e.g. two action spaces for the same action), even if the entity is currently untracked. The location in this case is the difference in the two spaces' application-specified transforms relative to that common entity. [kotlinc] [kotlinc] The runtime should return a location with #SPACE_LOCATION_POSITION_VALID_BIT set and #SPACE_LOCATION_POSITION_TRACKED_BIT unset for spaces tracking two static entities in the world when their relative pose is known to the runtime. This enables applications to make use of the runtime?s latest knowledge of the world, even during tracking loss. [kotlinc] [kotlinc] If an ##XrSpaceVelocity structure is chained to the {@code next} pointer of ##XrSpaceLocation and the velocity is observed or can be calculated by the runtime, the runtime must fill in the linear velocity of the origin of space within the reference frame of {@code baseSpace} and set the #SPACE_VELOCITY_LINEAR_VALID_BIT. Similarly, if an ##XrSpaceVelocity structure is chained to the {@code next} pointer of ##XrSpaceLocation and the angular velocity is observed or can be calculated by the runtime, the runtime must fill in the angular velocity of the origin of space within the reference frame of {@code baseSpace} and set the #SPACE_VELOCITY_ANGULAR_VALID_BIT. [kotlinc] [kotlinc] The following example code shows how an application can get both the location and velocity of a space within a base space using the #LocateSpace() function by chaining an ##XrSpaceVelocity to the next pointer of ##XrSpaceLocation and calling #LocateSpace().

Description
[kotlinc] #WaitFrame() throttles the application frame loop in order to synchronize application frame submissions with the display. #WaitFrame() returns a predicted display time for the next time that the runtime predicts a composited frame will be displayed. The runtime may affect this computation by changing the return values and throttling of #WaitFrame() in response to feedback from frame submission and completion times in #EndFrame(). An application must eventually match each #WaitFrame() call with one call to #BeginFrame(). A subsequent #WaitFrame() call must block until the previous frame has been begun with #BeginFrame() and must unblock independently of the corresponding call to #EndFrame(). When less than one frame interval has passed since the previous return from #WaitFrame(), the runtime should block until the beginning of the next frame interval. If more than one frame interval has passed since the last return from #WaitFrame(), the runtime may return immediately or block until the beginning of the next frame interval. [kotlinc] [kotlinc] In the case that an application has pipelined frame submissions, the application should compute the appropriate target display time using both the predicted display time and predicted display interval. The application should use the computed target display time when requesting space and view locations for rendering. [kotlinc] [kotlinc] The ##XrFrameState{@code ::predictedDisplayTime} returned by #WaitFrame() must be monotonically increasing. [kotlinc] [kotlinc] The runtime may dynamically adjust the start time of the frame interval relative to the display hardware?s refresh cycle to minimize graphics processor contention between the application and the compositor. [kotlinc] [kotlinc] #WaitFrame() must be callable from any thread, including a different thread than #BeginFrame()/#EndFrame() are being called from. [kotlinc] [kotlinc] Calling #WaitFrame() must be externally synchronized by the application, concurrent calls may result in undefined behavior. [kotlinc] [kotlinc] The runtime must return #ERROR_SESSION_NOT_RUNNING if the {@code session} is not running. [kotlinc] [kotlinc]
Note
[kotlinc] The engine simulation should advance based on the display time. Every stage in the engine pipeline should use the exact same display time for one particular application-generated frame. An accurate and consistent display time across all stages and threads in the engine pipeline is important to avoid object motion judder. If the application has multiple pipeline stages, the application should pass its computed display time through its pipeline, as #WaitFrame() must be called only once per frame. [kotlinc]

C Specification
[kotlinc] The #EndFrame() function is defined as: [kotlinc] [kotlinc] 

  [kotlinc] ?XrResult xrEndFrame(
  [kotlinc] ?    XrSession                                   session,
  [kotlinc] ?    const XrFrameEndInfo*                       frameEndInfo);
[kotlinc] [kotlinc]
Description
[kotlinc] #EndFrame() may return immediately to the application. ##XrFrameEndInfo{@code ::displayTime} should be computed using values returned by #WaitFrame(). The runtime should be robust against variations in the timing of calls to #WaitFrame(), since a pipelined system may call #WaitFrame() on a separate thread from #BeginFrame() and #EndFrame() without any synchronization guarantees. [kotlinc] [kotlinc]
Note
[kotlinc] An accurate predicted display time is very important to avoid black pull-in by reprojection and to reduce motion judder in case the runtime does not implement a translational reprojection. Reprojection should never display images before the display refresh period they were predicted for, even if they are completed early, because this will cause motion judder just the same. In other words, the better the predicted display time, the less latency experienced by the user. [kotlinc]
[kotlinc] [kotlinc] Every call to #EndFrame() must be preceded by a successful call to #BeginFrame(). Failure to do so must result in #ERROR_CALL_ORDER_INVALID being returned by #EndFrame(). ##XrFrameEndInfo may reference swapchains into which the application has rendered for this frame. From each {@code XrSwapchain} only one image index is implicitly referenced per frame, the one corresponding to the last call to #ReleaseSwapchainImage(). However, a specific swapchain (and by extension a specific swapchain image index) may be referenced in ##XrFrameEndInfo multiple times. This can be used for example to render a side by side image into a single swapchain image and referencing it twice with differing image rectangles in different layers. [kotlinc] [kotlinc] If no layers are provided then the display must be cleared. [kotlinc] [kotlinc] #ERROR_LAYER_INVALID must be returned if an unknown, unsupported layer type, or {@code NULL} pointer is passed as one of the ##XrFrameEndInfo::layers. [kotlinc] [kotlinc] #ERROR_LAYER_INVALID must be returned if a layer references a swapchain that has no released swapchain image. [kotlinc] [kotlinc] #ERROR_LAYER_LIMIT_EXCEEDED must be returned if ##XrFrameEndInfo::layerCount exceeds ##XrSystemGraphicsProperties::maxLayerCount or if the runtime is unable to composite the specified layers due to resource constraints. [kotlinc] [kotlinc] #ERROR_SWAPCHAIN_RECT_INVALID must be returned if ##XrFrameEndInfo::layers contains a composition layer which references pixels outside of the associated swapchain image or if negatively sized. [kotlinc] [kotlinc] #ERROR_ENVIRONMENT_BLEND_MODE_UNSUPPORTED must be returned if ##XrFrameEndInfo::environmentBlendMode is not supported. [kotlinc] [kotlinc] #ERROR_SESSION_NOT_RUNNING must be returned if the {@code session} is not running. [kotlinc] [kotlinc]
Note
[kotlinc] Applications should discard frames for which #EndFrame() returns a recoverable error over attempting to resubmit the frame with different frame parameters to provide a more consistent experience across different runtime implementations. [kotlinc]

[kotlinc] [kotlinc]
Description
[kotlinc] The #LocateViews() function returns the view and projection info for a particular display time. This time is typically the target display time for a given frame. Repeatedly calling #LocateViews() with the same time may not necessarily return the same result. Instead the prediction gets increasingly accurate as the function is called closer to the given time for which a prediction is made. This allows an application to get the predicted views as late as possible in its pipeline to get the least amount of latency and prediction error. [kotlinc] [kotlinc] #LocateViews() returns an array of ##XrView elements, one for each view of the specified view configuration type, along with an ##XrViewState containing additional state data shared across all views. The eye each view corresponds to is statically defined in {@code XrViewConfigurationType} in case the application wants to apply eye-specific rendering traits. The ##XrViewState and ##XrView member data may change on subsequent calls to #LocateViews(), and so applications must not assume it to be constant. [kotlinc] [kotlinc]

Description
[kotlinc] #StringToPath() retrieves the {@code XrPath} value for a well-formed path string. If such a value had not yet been assigned by the runtime to the provided path string in this {@code XrInstance}, one must be assigned at this point. All calls to this function with the same {@code XrInstance} and path string must retrieve the same {@code XrPath} value. Upon failure, #StringToPath() must return an appropriate {@code XrResult}, and may set the output parameter to #NULL_PATH.

Description
[kotlinc] #PathToString() retrieves the path name string associated with an {@code XrPath}, in the context of a given {@code XrInstance}, in the form of a {@code NULL} terminated string placed into a caller-allocated buffer. Since the mapping between a well-formed path name string and an {@code XrPath} is bijective, there will always be exactly one string for each valid {@code XrPath} value. This can be useful if the calling application receives an {@code XrPath} value that they had not previously retrieved via #StringToPath(). During the lifetime of the given {@code XrInstance}, the path name string retrieved by this function for a given valid {@code XrPath} will not change. For invalid paths, including #NULL_PATH, #ERROR_PATH_INVALID must be returned. [kotlinc] [kotlinc]

Enumerant Descriptions
[kotlinc] [kotlinc] [kotlinc] The #SESSION_STATE_UNKNOWN state must not be returned by the runtime, and is only defined to avoid 0 being a valid state. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_IDLE state indicates that the runtime considers the session is idle. Applications in this state should minimize resource consumption but continue to call #PollEvent() at some reasonable cadence. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_READY state indicates that the runtime desires the application to prepare rendering resources, begin its session and synchronize its frame loop with the runtime. The application does this by successfully calling #BeginSession() and then running its frame loop by calling #WaitFrame(), #BeginFrame() and #EndFrame() in a loop. If the runtime wishes to return the session to the #SESSION_STATE_IDLE state, it must wait until the application calls #BeginSession(). After returning from the #BeginSession() call, the runtime may then immediately transition forward through the #SESSION_STATE_SYNCHRONIZED state to the #SESSION_STATE_STOPPING state, to request that the application end this session. If the system supports a user engagement sensor and runtime is in #SESSION_STATE_IDLE state, the runtime should not transition to the #SESSION_STATE_READY state until the user starts engaging with the device. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_SYNCHRONIZED state indicates that the application has synchronized its frame loop with the runtime, but its frames are not visible to the user. The application should continue running its frame loop by calling #WaitFrame(), #BeginFrame() and #EndFrame(), although it should avoid heavy GPU work so that other visible applications can take CPU and GPU precedence. The application can save resources here by skipping rendering and not submitting any composition layers until #WaitFrame() returns an ##XrFrameState with {@code shouldRender} set to true. A runtime may use this frame synchronization to facilitate seamless switching from a previous XR application to this application on a frame boundary. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_VISIBLE state indicates that the application has synchronized its frame loop with the runtime, and the session?s frames will be visible to the user, but the session is not eligible to receive XR input. An application may be visible but not have focus, for example when the runtime is composing a modal pop-up on top of the application?s rendered frames. The application should continue running its frame loop, rendering and submitting its composition layers, although it may wish to pause its experience, as users cannot interact with the application at this time. It is important for applications to continue rendering when visible, even when they do not have focus, so the user continues to see something reasonable underneath modal pop-ups. Runtimes should make input actions inactive while the application is unfocused, and applications should react to an inactive input action by skipping rendering of that action?s input avatar (depictions of hands or other tracked objects controlled by the user). [kotlinc] [kotlinc] Receiving the #SESSION_STATE_FOCUSED state indicates that the application has synchronized its frame loop with the runtime, the session?s frames will be visible to the user, and the session is eligible to receive XR input. The runtime should only give one session XR input focus at any given time. The application should be running its frame loop, rendering and submitting composition layers, including input avatars (depictions of hands or other tracked objects controlled by the user) for any input actions that are active. The runtime should avoid rendering its own input avatars when an application is focused, unless input from a given source is being captured by the runtime at the moment. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_STOPPING state indicates that the runtime has determined that the application should halt its rendering loop. Applications should exit their rendering loop and call #EndSession() when in this state. A possible reason for this would be to minimize contention between multiple applications. If the system supports a user engagement sensor and the session is running, the runtime should transition to the #SESSION_STATE_STOPPING state when the user stops engaging with the device. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_EXITING state indicates the runtime wishes the application to terminate its XR experience, typically due to a user request via a runtime user interface. Applications should gracefully end their process when in this state if they do not have a non-XR user experience. [kotlinc] [kotlinc] Receiving the #SESSION_STATE_LOSS_PENDING state indicates the runtime is no longer able to operate with the current session, for example due to the loss of a display hardware connection. An application should call #DestroySession() and may end its process or decide to poll #GetSystem() at some reasonable cadence to get a new {@code XrSystemId}, and re-initialize all graphics resources related to the new system, and then create a new session using #CreateSession(). After the event is queued, subsequent calls to functions that accept {@code XrSession} parameters must no longer return any success code other than #SESSION_LOSS_PENDING for the given {@code XrSession} handle. The #SESSION_LOSS_PENDING success result is returned for an unspecified grace period of time, and the functions that return it simulate success in their behavior. If the runtime has no reasonable way to successfully complete a given function (e.g. #CreateSwapchain()) when a lost session is pending, or if the runtime is not able to provide the application a grace period, the runtime may return #ERROR_SESSION_LOST. Thereafter, functions which accept {@code XrSession} parameters for the lost session may return #ERROR_SESSION_LOST to indicate that the function failed and the given session was lost. The {@code XrSession} handle and child handles are henceforth unusable and should be destroyed by the application in order to immediately free up resources associated with those handles.

[kotlinc] [kotlinc]
C Specification
[kotlinc] Function pointers for all OpenXR functions can be obtained with the function #GetInstanceProcAddr(). [kotlinc] [kotlinc] 

  [kotlinc] ?XrResult xrGetInstanceProcAddr(
  [kotlinc] ?    XrInstance                                  instance,

[kotlinc] [kotlinc]
Description
[kotlinc] #GetInstanceProcAddr() itself is obtained in a platform- and loader- specific manner. Typically, the loader library will export this function as a function symbol, so applications can link against the loader library, or load it dynamically and look up the symbol using platform-specific APIs. Loaders must export function symbols for all core OpenXR functions. Because of this, applications that use only the core OpenXR functions have no need to use #GetInstanceProcAddr(). [kotlinc] [kotlinc] Because an application can call #GetInstanceProcAddr() before creating an instance, #GetInstanceProcAddr() returns a valid function pointer when the {@code instance} parameter is #NULL_HANDLE and the {@code name} parameter is one of the following strings: [kotlinc] [kotlinc]
No Instance Required
[kotlinc] [kotlinc] [kotlinc] #GetInstanceProcAddr() must return #ERROR_HANDLE_INVALID if {@code name} is not one of the above strings and {@code instance} is #NULL_HANDLE. #GetInstanceProcAddr() may return #ERROR_HANDLE_INVALID if {@code name} is not one of the above strings and {@code instance} is invalid but not #NULL_HANDLE. [kotlinc] [kotlinc] #GetInstanceProcAddr() must return #ERROR_FUNCTION_UNSUPPORTED if {@code instance} is a valid instance and the string specified in {@code name} is not the name of an OpenXR core or enabled extension function. [kotlinc] [kotlinc] If {@code name} is the name of an extension function, then the result returned by #GetInstanceProcAddr() will depend upon how the {@code instance} was created. If {@code instance} was created with the related extension?s name appearing in the ##XrInstanceCreateInfo{@code ::enabledExtensionNames} array, then #GetInstanceProcAddr() returns a valid function pointer. If the related extension?s name did not appear in the ##XrInstanceCreateInfo{@code ::enabledExtensionNames} array during the creation of {@code instance}, then #GetInstanceProcAddr() returns #ERROR_FUNCTION_UNSUPPORTED. Because of this, function pointers returned by #GetInstanceProcAddr() using one {@code XrInstance} may not be valid when used with objects related to a different {@code XrInstance}. [kotlinc] [kotlinc] The returned function pointer is of type {@code PFN_xrVoidFunction}, and must be cast to the type of the function being queried. [kotlinc] [kotlinc] The table below defines the various use cases for #GetInstanceProcAddr() and return value (?{@code fp}? is ?{@code function pointer}?) for each case. [kotlinc] [kotlinc]

[kotlinc] [kotlinc]
Description
[kotlinc] For a {@code time} in the past, the runtime should locate the spaces based on the runtime?s most accurate current understanding of how the world was at that historical time. [kotlinc] [kotlinc] For a {@code time} in the future, the runtime should locate the spaces based on the runtime?s most up-to-date prediction of how the world will be at that future time. [kotlinc] [kotlinc] The minimum valid range of values for {@code time} are described in prediction-time-limits. For values of {@code time} outside this range, #LocateSpace() may return a location with no position and #SPACE_LOCATION_POSITION_VALID_BIT unset. [kotlinc] [kotlinc] Some devices improve their understanding of the world as the device is used. The location returned by #LocateSpace() for a given {@code space}, {@code baseSpace} and {@code time} may change over time, even for spaces that track static objects, as one or both spaces adjust their origins. [kotlinc] [kotlinc] During tracking loss of {@code space} relative to {@code baseSpace}, runtimes should continue to provide inferred or last-known {@code position} and {@code orientation} values. These inferred poses can, for example, be based on neck model updates, inertial dead reckoning, or a last-known position, so long as it is still reasonable for the application to use that pose. While a runtime is providing position data, it must continue to set #SPACE_LOCATION_POSITION_VALID_BIT but it can clear #SPACE_LOCATION_POSITION_TRACKED_BIT to indicate that the position is inferred or last-known in this way. [kotlinc] [kotlinc] If the runtime has not yet observed even a last-known pose for how to locate {@code space} in {@code baseSpace} (e.g. one space is an action space bound to a motion controller that has not yet been detected, or the two spaces are in disconnected fragments of the runtime?s tracked volume), the runtime should return a location with no position and #SPACE_LOCATION_POSITION_VALID_BIT unset. [kotlinc] [kotlinc] The runtime must return a location with both #SPACE_LOCATION_POSITION_VALID_BIT and #SPACE_LOCATION_POSITION_TRACKED_BIT set when locating {@code space} and {@code baseSpace} if both spaces were created relative to the same entity (e.g. two action spaces for the same action), even if the entity is currently untracked. The location in this case is the difference in the two spaces' application-specified transforms relative to that common entity. [kotlinc] [kotlinc] The runtime should return a location with #SPACE_LOCATION_POSITION_VALID_BIT set and #SPACE_LOCATION_POSITION_TRACKED_BIT unset for spaces tracking two static entities in the world when their relative pose is known to the runtime. This enables applications to make use of the runtime?s latest knowledge of the world, even during tracking loss. [kotlinc] [kotlinc] If an ##XrSpaceVelocity structure is chained to the {@code next} pointer of ##XrSpaceLocation and the velocity is observed or can be calculated by the runtime, the runtime must fill in the linear velocity of the origin of space within the reference frame of {@code baseSpace} and set the #SPACE_VELOCITY_LINEAR_VALID_BIT. Similarly, if an ##XrSpaceVelocity structure is chained to the {@code next} pointer of ##XrSpaceLocation and the angular velocity is observed or can be calculated by the runtime, the runtime must fill in the angular velocity of the origin of space within the reference frame of {@code baseSpace} and set the #SPACE_VELOCITY_ANGULAR_VALID_BIT. [kotlinc] [kotlinc] The following example code shows how an application can get both the location and velocity of a space within a base space using the #LocateSpace() function by chaining an ##XrSpaceVelocity to the next pointer of ##XrSpaceLocation and calling #LocateSpace().

[kotlinc] [kotlinc]
Description
[kotlinc] #WaitFrame() throttles the application frame loop in order to synchronize application frame submissions with the display. #WaitFrame() returns a predicted display time for the next time that the runtime predicts a composited frame will be displayed. The runtime may affect this computation by changing the return values and throttling of #WaitFrame() in response to feedback from frame submission and completion times in #EndFrame(). An application must eventually match each #WaitFrame() call with one call to #BeginFrame(). A subsequent #WaitFrame() call must block until the previous frame has been begun with #BeginFrame() and must unblock independently of the corresponding call to #EndFrame(). When less than one frame interval has passed since the previous return from #WaitFrame(), the runtime should block until the beginning of the next frame interval. If more than one frame interval has passed since the last return from #WaitFrame(), the runtime may return immediately or block until the beginning of the next frame interval. [kotlinc] [kotlinc] In the case that an application has pipelined frame submissions, the application should compute the appropriate target display time using both the predicted display time and predicted display interval. The application should use the computed target display time when requesting space and view locations for rendering. [kotlinc] [kotlinc] The ##XrFrameState{@code ::predictedDisplayTime} returned by #WaitFrame() must be monotonically increasing. [kotlinc] [kotlinc] The runtime may dynamically adjust the start time of the frame interval relative to the display hardware?s refresh cycle to minimize graphics processor contention between the application and the compositor. [kotlinc] [kotlinc] #WaitFrame() must be callable from any thread, including a different thread than #BeginFrame()/#EndFrame() are being called from. [kotlinc] [kotlinc] Calling #WaitFrame() must be externally synchronized by the application, concurrent calls may result in undefined behavior. [kotlinc] [kotlinc] The runtime must return #ERROR_SESSION_NOT_RUNNING if the {@code session} is not running. [kotlinc] [kotlinc]
Note
[kotlinc] The engine simulation should advance based on the display time. Every stage in the engine pipeline should use the exact same display time for one particular application-generated frame. An accurate and consistent display time across all stages and threads in the engine pipeline is important to avoid object motion judder. If the application has multiple pipeline stages, the application should pass its computed display time through its pipeline, as #WaitFrame() must be called only once per frame. [kotlinc]

Description
[kotlinc] #EndFrame() may return immediately to the application. ##XrFrameEndInfo{@code ::displayTime} should be computed using values returned by #WaitFrame(). The runtime should be robust against variations in the timing of calls to #WaitFrame(), since a pipelined system may call #WaitFrame() on a separate thread from #BeginFrame() and #EndFrame() without any synchronization guarantees. [kotlinc] [kotlinc]
Note
[kotlinc] An accurate predicted display time is very important to avoid black pull-in by reprojection and to reduce motion judder in case the runtime does not implement a translational reprojection. Reprojection should never display images before the display refresh period they were predicted for, even if they are completed early, because this will cause motion judder just the same. In other words, the better the predicted display time, the less latency experienced by the user. [kotlinc]
[kotlinc] [kotlinc] Every call to #EndFrame() must be preceded by a successful call to #BeginFrame(). Failure to do so must result in #ERROR_CALL_ORDER_INVALID being returned by #EndFrame(). ##XrFrameEndInfo may reference swapchains into which the application has rendered for this frame. From each {@code XrSwapchain} only one image index is implicitly referenced per frame, the one corresponding to the last call to #ReleaseSwapchainImage(). However, a specific swapchain (and by extension a specific swapchain image index) may be referenced in ##XrFrameEndInfo multiple times. This can be used for example to render a side by side image into a single swapchain image and referencing it twice with differing image rectangles in different layers. [kotlinc] [kotlinc] If no layers are provided then the display must be cleared. [kotlinc] [kotlinc] #ERROR_LAYER_INVALID must be returned if an unknown, unsupported layer type, or {@code NULL} pointer is passed as one of the ##XrFrameEndInfo::layers. [kotlinc] [kotlinc] #ERROR_LAYER_INVALID must be returned if a layer references a swapchain that has no released swapchain image. [kotlinc] [kotlinc] #ERROR_LAYER_LIMIT_EXCEEDED must be returned if ##XrFrameEndInfo::layerCount exceeds ##XrSystemGraphicsProperties::maxLayerCount or if the runtime is unable to composite the specified layers due to resource constraints. [kotlinc] [kotlinc] #ERROR_SWAPCHAIN_RECT_INVALID must be returned if ##XrFrameEndInfo::layers contains a composition layer which references pixels outside of the associated swapchain image or if negatively sized.

[kotlinc] [kotlinc] #ERROR_SESSION_NOT_RUNNING must be returned if the {@code session} is not running. [kotlinc] [kotlinc]
Note
[kotlinc] Applications should discard frames for which #EndFrame() returns a recoverable error over attempting to resubmit the frame with different frame parameters to provide a more consistent experience across different runtime implementations. [kotlinc]

Description
[kotlinc] The #LocateViews() function returns the view and projection info for a particular display time. This time is typically the target display time for a given frame. Repeatedly calling #LocateViews() with the same time may not necessarily return the same result. Instead the prediction gets increasingly accurate as the function is called closer to the given time for which a prediction is made. This allows an application to get the predicted views as late as possible in its pipeline to get the least amount of latency and prediction error. [kotlinc] [kotlinc] #LocateViews() returns an array of ##XrView elements, one for each view of the specified view configuration type, along with an ##XrViewState containing additional state data shared across all views. The eye each view corresponds to is statically defined in {@code XrViewConfigurationType} in case the application wants to apply eye-specific rendering traits. The ##XrViewState and ##XrView member data may change on subsequent calls to #LocateViews(), and so applications must not assume it to be constant. [kotlinc] [kotlinc]

[kotlinc] [kotlinc]
Description
[kotlinc] Action handles can be destroyed by calling #DestroyAction(). Handles for actions that are part of an action set are automatically destroyed when the action set?s handle is destroyed. [kotlinc] [kotlinc] The implementation must not destroy the underlying resources for an action when #DestroyAction() is called. Those resources are still used to make action spaces locatable and when processing action priority in #SyncActions(). Destroying the action handle removes the application?s access to these resources, but has no other change on actions. [kotlinc] [kotlinc] Resources for all actions in an instance must be freed when the instance containing those actions sets is destroyed. [kotlinc] [kotlinc]
