hi! I wrote this a million years ago and I really do not remember. It does all the processing on the CPU so it might be a bit slow. I think that ofxFX has the same thing implemented in shaders. I'll try to give a look at it. If you have any improvement please PR
@moebiussurfing Actually now I recall that this addon then became one of the OF examples https://github.com/openframeworks/openFrameworks/tree/patch-release/examples/graphics/lutFilterExample
nevermind. I found this alternative that uses the GPU: https://github.com/yasuhirohoshino/ofxGpuLut but must convert the more standard .cube LUT's to .png format by hand.
I modified the example to process an image and seems to works, but it makes a lot of process/debug into the console and takes several seconds to update/process the image?
is that the expected behavior?
