Re: [Openexr-user] CTL Backend

[Florian Kainz]

As far as I know there is no backend that executes the actual CTL program
on the GPU.  The playexr viewer executes the CTL program on the CPU and
derives a 3D LUT from it. The LUT is then sent to the GPU and applied in
real time during image playback.
