Function ovr_sys::opengl::ovr_CreateMirrorTextureGL

pub unsafe extern "C" fn ovr_CreateMirrorTextureGL(
    session: ovrSession,
    desc: *const ovrMirrorTextureDesc,
    out_MirrorTexture: *mut ovrMirrorTexture
) -> ovrResult

Creates a Mirror Texture which is auto-refreshed to mirror Rift contents produced by this application.

A second call to ovr_CreateMirrorTextureGL for a given ovrSession before destroying the first one is not supported and will result in an error return.

in session Specifies an ovrSession previously returned by ovr_Create.

in desc Specifies the requested mirror texture description.

out out_MirrorTexture Specifies the created ovrMirrorTexture, which will be valid upon a successful return value, else it will be NULL. This texture must be eventually destroyed via ovr_DestroyMirrorTexture before destroying the session with ovr_Destroy.

Returns an ovrResult indicating success or failure. In the case of failure, use ovr_GetLastErrorInfo to get more information.

Note: The format provided should be thought of as the format the distortion compositor will use when writing into the mirror texture. It is highly recommended that mirror textures are requested as sRGB formats because the distortion compositor does sRGB-correct rendering. If the application requests a non-sRGB format (e.g. R8G8B8A8_UNORM) as the mirror texture, then the application might have to apply a manual linear-to-gamma conversion when reading from the mirror texture. Failure to do so can result in incorrect gamma conversions leading to gamma-curve artifacts and color banding.
