Camera.SetStereoViewMatrix

Parameters

Description

Sets a custom view matrix for a specific stereoscopic eye.

In most cases you should use the view matrices provided by the VR SDK to ensure accurate stereoscopic rendering. However, in some scenarios it can be useful to override the view matrices to achieve specific effects. For example, custom view matrices would be required to implement binoculars in VR.

If custom view matrices have been set, then the Camera will analyze the view matrices to determine whether it is safe to use a single cull pass or if it must separately cull each eye. Use Camera.areVRStereoViewMatricesWithinSingleCullTolerance to find out which will be used.

Calling Camera.ResetStereoViewMatrices will revert the camera to using view matrices provided by the VR SDK. Note that the Camera.stereoSeparation will not be applied until you call Camera.ResetStereoViewMatrices.
