[Openexr-user] CTL Backend

[Bo Zhou]

Hello folks,

Is there a project that to make a GPU-based CTL backend ? The current
version of CTL seems a little older.

Thanks.

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.
