It took a little to figure out (first I had to go through remembering how to use Houdini, after such a long time… Sorry!!) but I can finally color a mesh using information from a Point Cloud. One of our interns was showing his research on low-cost 3D scanning (decent stuff!) and he couldn’t figure out how to transfer the color information to the reconstructed model. I found some other solutions to the whole 3D scanning issue, but still wanted to give it a go in Houdini.
When I offered to try with his model he was a bit concerned and ended up not giving me the files, but I managed to generate a test point cloud and figured out a VOP-SOP that does the trick. :) Next step will be setting up the low cost 3D scanner! :D
