• getSBSUpstreamPMV

  public static void getSBSUpstreamPMV(ViewerPose viewerPose, StereoDeviceRenderer.Eye eye, float zNear, float zFar, float[] mat4Projection, float[] mat4Modelview)

  Calculates the Side By Side, SBS, projection- and modelview matrix for one eye.

  #updateViewerPose(int) must be called upfront.

  This method merely exist as an example implementation to compute the matrices, which shall be adopted by the upstream client code.

  Parameters:

  viewerPose -

  eye -

  zNear - frustum near value

  zFar - frustum far value

  mat4Projection - float[16] projection matrix result

  mat4Modelview - float[16] modelview matrix result
