Stereo3D

Stereo3DMatrixHelper.h/.cpp contains a prototype set of functions for creating Stereo 3D projections. It was never fully validated or completed, but might be a useful starting point.

This function filled out a default STEREO_PARAMETERS which you could then modify before passing on to the other functions.

void StereoCreateDefaultParameters(_Out_ STEREO_PARAMETERS* pStereoParameters);

These functions compute the stereo projection matrices. You'd call it twice, once for STEREO_CHANNEL_LEFT and once for STEREO_CHANNEL_RIGHT to get two matrices. If you pass nullptr for the pStereoParameters parameter, you get the values obtained from StereoCreateDefaultParameters.

XMMATRIX StereoProjectionFovLH(_In_opt_ const STEREO_PARAMETERS* pStereoParameters,
    STEREO_CHANNEL Channel, float FovAngleY, float AspectRatio,
    float NearZ, float FarZ, STEREO_MODE StereoMode);

XMMATRIX StereoProjectionFovRH(_In_opt_ const STEREO_PARAMETERS* pStereoParameters,
    STEREO_CHANNEL Channel, float FovAngleY, float AspectRatio,
    float NearZ, float FarZ, STEREO_MODE StereoMode);
