Re: State of OCIO development re: CPU/GPU mismatches

This issue not just tetrahedral interpolation, it is the fact that the existing OCIO OpenGL GPU path folds all LUTs into a single 3D LUT, and this is not sufficient for many transformations (especially ACES when both 2D and 3D LUTs are being used). ///d@ Dennis Adams Sony Creative Software

It's still not as good as tetrahedral interpolation but it is close enough for gpu playback. Kevin Wheatley had some good slides & charts on this from his ACES presentation at Digipro if you have an ACM account.
