possible implementation of overlapping and touching test? about trimesh HOT 3 CLOSED

Yeah, the point contains test is quite slow, and without watertight meshes not going to tell you very much. Some ideas:

1. If you have 2 watertight meshes you can use boolean intersection methods of the Trimesh objects (which uses blender or openSCAD as a backend). This is always going to be a bit slow as well, and can give wonky results from precision issues.

2. You probably want an actual collision detection library- FCL is very popular and this python binding looks pretty interesting: https://github.com/jf---/python-fcl

Thanks!
The python-fcl, which uses bvh, does the work very well.
It seems most of the collision test libs like bullet3 all use bvh.

Btw, I've built a conda package for python-fcl.

If you use conda

you can easily install the python-fcl through:

conda config --add channels http://conda.anaconda.org/lorinma
conda install python-fcl=0.4.1

perhaps you can incorporate fcl into trimesh in this way.
