Display error of running program unity

Or display such an error：
`UnassignedReferenceException: The variable clothSolver of GPUClothSimulation has not been assigned.
You probably need to assign the clothSolver variable of the GPUClothSimulation script in the inspector.

as mentioned in #5 , this project is really in a paused state for now until further announcement xd.

for now, I can only point you to some resources:

PBD / XPBD by Matthias Muller
for collision you can look for:

• Binary volume hierarchy (https://developer.nvidia.com/blog/thinking-parallel-part-ii-tree-traversal-gpu/)
• or you can use Spatial Hashing by Matthias Muller (again xd)

hope it helps!

In China, I saw that this course has just started, but it is still very difficult. I haven’t done it before and feel that I can’t do it hahaha. Are there any open source libraries or recommended projects?

for gpu accelerated cloth simulation in unity, here is one that I looked at when starting out: https://github.com/Ninjajie/Fusion
