Returns how well the headset is being tracked, as bit flags. 1 - orientation is valid 2 - position is valid 4 - orientation is actively tracked 8 - position is actively tracked 15 means fully tracked. The headset view needs both valid flags (1 and 2); without them the engine stops drawing the stereo view until tracking returns. A headset that is losing sight of its sensors can still give valid estimates with the actively tracked flags cleared. Returns 0 when there is no usable tracking sample yet. Use it to show a "tracking lost" message, or to wait for good tracking before VRRecenter. Automatic VR is experimental, and works in 64-bit Windows programs through an OpenXR runtime and Direct3D 12. In 32-bit programs the commands are there, so the same source compiles, but InitVR returns False and VRLastError says why. For the full story - setup, frame rules and limitations - see the Automatic PC VR guide and its complete AutomaticVR.bb sample. See also: VRRecenter, VRVisible, VRState. |
