Missing OBJ files in scenes/Collisions directory

[ricetwice]

Hi there, I was trying to use your source code for the paper Repulsive Surfaces. However, I noticed that there is a folder named scenes/Collisions that seems to be missing the required OBJ files.

Could you kindly consider adding the missing obj files to the scenes/Collisions folder so that others can reproduce your work seamlessly?

Thank you for your contribution!
