In OculusWorldDemo, when enabled the Face2 Layer, it will enable the Layer4, which type is ovrLayerType_EyeMatrix the structure is ovrLayerEyeMatrix, it contains a member called Matrix which defined as follows
/// Specifies the mapping from a view-space vector
/// to a UV coordinate on the textures given above.
/// P = (x,y,z,1)*Matrix
/// TexU = P.x/P.z
/// TexV = P.y/P.z
ovrMatrix4f Matrix[ovrEye_Count];
i dont exactly know what does matrix (x, y, z, 1) means, which is x, y and z,
is there anyone knows which does view-space vector means, and x,y,z values?
I've searched for answers, but there is no result, is there anybody knows? o:)
