One one the ICC GSoC projects is to create a 3D gamut viewer for gnome-color-manager. I've been doing some initial research on this in case any student elects to do this task. So far I have concluded using clutter and mash to display a generated PLY file of the profile gamut is probably the best way to integrate this into the UI. This way, the ply file can be viewed in any of the viewers in existence, and I don't have to worry about any of the icky 3D OpenGL stuff.
So, to create a PLY file, I need to process a lot of data with lcms or poke around in the profile internals. I'm wondering if there is any shortcut anybody knows on how to generate this kind of 3D gamut surface, with sufficient accuracy to visually compare sRGB and some random CMYK gamut, for instance. I've looked at icc_examin, but this merely wraps the argyllcms iccgamut, which outputs a VRML file. Ideally I want to do this in a thread in gcm-viewer using lcms2. I'm guessing my Lab range wants to be 0..100,0..100,0..100 but I'm open to ideas on how to optimize the amount of data to pass to the lcms transform. I tried the brute force approach, and that was, well, glacially slow.
