These interfaces are about the model view transform and projection. To get the projection matrix for a specific eye.
- WVR_GetProjection returns the 4x4 float matrix.
- WVR_GetClippingPlaneBoundary retrieves the boundary of the clipping plane of the frustum.
- WVR_GetTransformFromEyeToHead returns the transform from eye space to the head space.
- WVR_GetRenderTargetSize retrieves the suggested size of the render target.
- WVR_SetOverfillRatio to enlarge not only texture size but also reduce the black edge to fulfill screen. For more details, refer to Render runtime tutorial.
