I'm looking for a (preferably free) lib for the following: I want to do a Trace Ray through my scene, but not for a single starting point, but rather a starting shape.
So instead of having the origin being a point and the trace a line, I want the origin to be a shape (say, circle) and the trace a cylinder.
I found this page here: https://github.com/jslee02/awesome-collision-detection , but I still could not find this feature.
Unreal has UWorld::SweepMultiByChannel, which is pretty much what I want (but I'm not in UE...)
Thanks in advance!
