}Expand description
Describes a layer that specifies a monoscopic or stereoscopic view.
This is the kind of layer that’s typically used as layer 0 to ovr_SubmitFrame,
as it is the kind of layer used to render a 3D stereoscopic view.
Three options exist with respect to mono/stereo texture usage:
ColorTexture[0]andColorTexture[1]contain the left and right stereo renderings, respectively.Viewport[0]andViewport[1]refer toColorTexture[0]andColorTexture[1], respectively.ColorTexture[0]contains both the left and right renderings,ColorTexture[1]is NULL, andViewport[0]andViewport[1]refer to sub-rects withColorTexture[0].ColorTexture[0]contains a single monoscopic rendering, andViewport[0]andViewport[1]both refer to that rendering.
Fields§
§_align: [isize; 0]§Header: ovrLayerHeaderHeader.Type must be ovrLayerType_EyeFov.
ColorTexture: [ovrTextureSwapChain; 2]ovrTextureSwapChains for the left and right eye respectively.
The second one of which can be NULL for cases described above.
Viewport: [ovrRecti; 2]Specifies the ColorTexture sub-rect UV coordinates.
Both Viewport[0] and Viewport[1] must be valid.
Fov: [ovrFovPort; 2]The viewport field of view.
RenderPose: [ovrPosef; 2]Specifies the position and orientation of each eye view, with the position specified in meters.
RenderPose will typically be the value returned from ovr_CalcEyePoses,
but can be different in special cases if a different head pose is used for rendering.
SensorSampleTime: f64Specifies the timestamp when the source ovrPosef (used in calculating RenderPose)
was sampled from the SDK. Typically retrieved by calling ovr_GetTimeInSeconds
around the instant the application calls ovr_GetTrackingState
The main purpose for this is to accurately track app tracking latency.
