Hi,
I need to translate a bunch of RGB color to fit the rgb4k_map.ppm so i'm looking for the formula.

Can you help me ?

This translation is a bit complex. I can send you the C++ function used to encode the RGB to UV map, but why do you need it? The plugin should be able to use any RGB Cd attribute to get the final color in the rgb4k_map.ppm texture.

Thanks,

Hi juanjgon,
I try to optimize computation time to get photogrammetric point cloud ready for rendering. It time consuming to convert millions points in houdini.

This can realy help me :)
