Could Taichi be used for 3D object collision detection?

[ANYMS-A]

Concisely describe the proposed feature Hi, I was recently doing a task related with collision detection. I need to detect whether the mesh vertices of clothes intersected with the vertices of human body mesh, while the 3D position of these vertices are given.

I'd like to know could mpm method be used to solve this problem fastly?

Many thanks!

Intresting, not sure if this helps: https://github.com/yuanming-hu/taichi/blob/master/examples/mpm_lagrangian_forces.py

Applying forces to grid body on collision. I may write a 3D version if you want :-)

Hi, I'd like to run the demo of the link you gave out, but it raise an error:

[Taichi] mode=release
[Taichi] version 0.6.19, llvm 10.0.0, commit 9f11a55e, python 3.7.6

How should I fix it ? Many thanks!
