collision detection in VREP

Post by scut_whg »

What is the principle of collision detection in VREP? Or how is the state validity check in VREP implemented?

Hello,

CoppeliaSim/V-REP uses its own collision checking routines, based on a hierarchy of object-oriented bounding boxes, that wrap triangles composing the mesh. Detection is triangle-triangle exact. Same for the minimum distance calculation.

Cheers

Special thanks to your answer! It is a little difficult for me to simply look at the source code. Does the source code of this collision detection have relevant theoretical literature support? Where can I read it? This will help me understand.
