py_geometry_constraint

The geometryConstraint function in Maya and similar functions in other languages are helpful to project points/vertices onto a mesh, locking their motion.

But I have found no similar implementations currently existing in python. After some research, referencing to:

1. facebookresearch/pytorch3d#193 and
2. facebookresearch/pytorch3d#1016

I present to you a geometryConstraint implementation in python, using pytorch3d.

Example output:

• blue points: vertices on mesh
• red lines: edges on mesh
• green points: points and their projection on the closest plane/faces
• black lines: line of projection

Development Environment

WSL Ubuntu-22.04 with python3.10
