New ofxAddon ofxGpuLutCube

openFrameworks addon to apply LUT (Color Lookup Table) filter shader from standard ‘.cube’ files. (sizes 16, 32, 64)


Awesome news! I’ve always been looking for something like this. I haven’t yet looked at the code, does the addon support saving the result to a file, too?
Also, I guess you’re using linear interpolation, not tetrahedral, right?

cool thanks @vvzen, hope it fits your desired use.

the example is not exporting any processed file. just processing live what you draw between begin/end but could be easy to add to your app.

sorry, but no idea about the used interpolation, maybe you can look into the source files I used, that are linked into the addon info.

I see some GL LINEAR. Why could be this important for?
