Continuing the discussion from Sketchup keeps crashing when I try to import a skull:
It would be a nice option. There are a number of very nice programs and libraries for performing mesh operations.
The way forward is to move from the pure-Ruby importer/exporter to a more generalized compiled extension for mesh importing, exporting , and modification. There are several open libraries available which have done most of the heavy-lifting as far as mesh processing goes. They “only” need integrated into a SketchUp extension. As you know, my experimentation shows that a SketchUp stl imported based on assimp outperforms the Ruby version considerably.
Here’s a short list of interesting libraries.
libigl looks very interesting.
