Package org.lwjgl.openvr

Class VRSystem

java.lang.Object

org.lwjgl.openvr.VRSystem

public class VRSystem
extends Object

Main interface for display, distortion, tracking, controller, and event access.

The IVRSystem interface provides access to display configuration information, tracking data, distortion functions, controller state, events, and device properties. It is the main interface of OpenVR and can be initialized and retrieved with the InitInternal function.

Many functions in IVRSystem use a tracked device index to identify a specific device attached to the computer. There will never be more than VR.k_unMaxTrackedDeviceCount devices active in the system at any given time. Their indices will be 0 (for the HMD) and 1-15 for the other devices.

The user should enumerate all adapters using IDXGIFactory::EnumAdapters and IDXGIAdapter::GetDesc to find the adapter with the matching LUID, or use IDXGIFactory4::EnumAdapterByLuid.

On 10.13+ for VR.ETextureType_TextureType_OpenGL returns the registryId of the renderer which should be used by the application. See Apple Technical Q&A QA1168 for information on enumerating GL Renderers, and the new kCGLRPRegistryIDLow and kCGLRPRegistryIDHigh CGLRendererProperty values in the 10.13 SDK.

Pre 10.13 for VR.ETextureType_TextureType_OpenGL returns 0, as there is no dependable way to correlate the HMDs MTLDevice with a GL Renderer.

VR.ETextureType_TextureType_OpenGL	VR.ETextureType_TextureType_Vulkan

nVRSystem_GetDeviceToAbsoluteTrackingPose

public static void nVRSystem_GetDeviceToAbsoluteTrackingPose(int eOrigin,

 int unTrackedDevicePoseArrayCount)

Unsafe version of: GetDeviceToAbsoluteTrackingPose

VRSystem_GetDeviceToAbsoluteTrackingPose

public static void VRSystem_GetDeviceToAbsoluteTrackingPose(int eOrigin,
 float fPredictedSecondsToPhotonsFromNow,
 TrackedDevicePose.Buffer pTrackedDevicePoseArray)

The pose that the tracker thinks that the HMD will be in at the specified number of seconds into the future. Pass 0 to get the state at the instant the method is called. Most of the time the application should calculate the time until the photons will be emitted from the display and pass that time into the method.

This is roughly analogous to the inverse of the view matrix in most applications, though many games will need to do some additional rotation or translation on top of the rotation and translation provided by the head pose.

For devices where bPoseIsValid is true the application can use the pose to position the device in question. The provided array can be any size up to VR.k_unMaxTrackedDeviceCount.

Seated experiences should call this method with VR.ETrackingUniverseOrigin_TrackingUniverseSeated and receive poses relative to the seated zero pose. Standing experiences should call this method with VR.ETrackingUniverseOrigin_TrackingUniverseStanding and receive poses relative to the Chaperone Play Area. VR.ETrackingUniverseOrigin_TrackingUniverseRawAndUncalibrated should probably not be used unless the application is the Chaperone calibration tool itself, but will provide poses relative to the hardware-specific coordinate system in the driver.

Parameters:

eOrigin - tracking universe that returned poses should be relative to. One of:

VR.ETrackingUniverseOrigin_TrackingUniverseSeated

VR.ETrackingUniverseOrigin_TrackingUniverseStanding

VR.ETrackingUniverseOrigin_TrackingUniverseRawAndUncalibrated

fPredictedSecondsToPhotonsFromNow - number of seconds from now to predict poses for. Positive numbers are in the future. Pass 0 to get the state at the instant the function is called.

The seated origin may or may not be inside the Play Area or Collision Bounds returned by IVRChaperone. Its position depends on what the user has set from the Dashboard settings and previous calls to ResetZeroPose.

 long __result)

VRSystem_GetHiddenAreaMesh

public static HiddenAreaMesh VRSystem_GetHiddenAreaMesh(int eEye,
 int type,
 HiddenAreaMesh __result)

Returns the hidden area mesh for the current HMD. The pixels covered by this mesh will never be seen by the user after the lens distortion is applied based on visibility to the panels. If this HMD does not have a hidden area mesh, the vertex data and count will be NULL and 0 respectively.

This mesh is meant to be rendered into the stencil buffer (or into the depth buffer setting nearz) before rendering each eye's view. This will improve performance by letting the GPU early-reject pixels the user will never see before running the pixel shader.

Note

Render this mesh with backface culling disabled since the winding order of the vertices can be different per-HMD or per-eye.

Parameters:

eEye - the eye to get the hidden area mesh for. One of:

VR.EVREye_Eye_Left

VR.EVREye_Eye_Right

type - one of:

Parameters:

eAxisType - the controller axis type to get a name for. One of:

VR.EVRControllerAxisType_k_eControllerAxis_None

VR.EVRControllerAxisType_k_eControllerAxis_TrackPad

VR.EVRControllerAxisType_k_eControllerAxis_Joystick

VR.EVRControllerAxisType_k_eControllerAxis_Trigger

VRSystem_IsInputAvailable

public static boolean VRSystem_IsInputAvailable()

Returns true if this application is receiving input from the system. This would return false if system-related functionality is consuming the input stream.

VRSystem_IsSteamVRDrawingControllers

public static boolean VRSystem_IsSteamVRDrawingControllers()

Returns true if SteamVR is drawing controllers on top of the application. Applications should consider not drawing anything attached to the user's hands in this case.

VRSystem_ShouldApplicationPause

public static boolean VRSystem_ShouldApplicationPause()

Returns true if the user has put SteamVR into a mode that is distracting them from the application. For applications where this is appropriate, the application should pause ongoing activity.

VRSystem_ShouldApplicationReduceRenderingWork

public static boolean VRSystem_ShouldApplicationReduceRenderingWork()

Returns true if SteamVR is doing significant rendering work and the game should do what it can to reduce its own workload. One common way to do this is to reduce the size of the render target provided for each eye.

VRSystem_PerformFirmwareUpdate

public static int VRSystem_PerformFirmwareUpdate(int unDeviceIndex)

Performs the actual firmware update if applicable.

The following events will be sent, if VR.EVRFirmwareError_VRFirmwareError_None was returned: VR.EVREventType_VREvent_FirmwareUpdateStarted, VR.EVREventType_VREvent_FirmwareUpdateFinished

Use the properties VR.ETrackedDeviceProperty_Prop_Firmware_UpdateAvailable_Bool, VR.ETrackedDeviceProperty_Prop_Firmware_ManualUpdate_Bool, and VR.ETrackedDeviceProperty_Prop_Firmware_ManualUpdateURL_String to figure our whether a firmware update is available, and to figure out whether its a manual update. VR.ETrackedDeviceProperty_Prop_Firmware_ManualUpdateURL_String should point to an URL describing the manual update process.

VRSystem_AcknowledgeQuit_Exiting

public static void VRSystem_AcknowledgeQuit_Exiting()

Call this to acknowledge to the system that VR.EVREventType_VREvent_Quit has been received and that the process is exiting. This extends the timeout until the process is killed.

nVRSystem_GetAppContainerFilePaths

public static int nVRSystem_GetAppContainerFilePaths(long pchBuffer,
 int unBufferSize)

Unsafe version of: GetAppContainerFilePaths

VRSystem_GetAppContainerFilePaths

public static int VRSystem_GetAppContainerFilePaths(@Nullable
 ByteBuffer pchBuffer)

Retrieves a null-terminated, semicolon-delimited list of UTF8 file paths that an application must have read access to when running inside of an app container.

Returns:

the number of bytes needed to hold the list

VRSystem_GetAppContainerFilePaths

public static String VRSystem_GetAppContainerFilePaths(int unBufferSize)

Retrieves a null-terminated, semicolon-delimited list of UTF8 file paths that an application must have read access to when running inside of an app container.

Returns:

the number of bytes needed to hold the list

nVRSystem_GetRuntimeVersion

public static long nVRSystem_GetRuntimeVersion()

Unsafe version of: GetRuntimeVersion

VRSystem_GetRuntimeVersion

@Nullable
public static String VRSystem_GetRuntimeVersion()

Returns the current version of the SteamVR runtime. The returned string will remain valid until ShutdownInternal is called.

NOTE: Is it not appropriate to use this version to test for the presence of any SteamVR feature. Only use this version number for logging or showing to a user, and not to try to detect anything at runtime. When appropriate, feature-specific presence information is provided by other APIs.
