What is the fastest way to determine collision between two objects (not bounding box)? I don’t need an accurate point of intersection or anything else beyond “do these things overlap anywhere?”
two usual questions:
how big your meshes (num faces)?,
and
what is fast enough for you?
Forgot one important thing: I am specifically looking for geometry intersection. So a smaller box completely contained inside a larger one should NOT return as a collision…
In my test case, my main mesh has ~2400 faces and I’ll be checking it against 60 or so smaller meshes that have 55 faces each.
Ideal goal: I want to test each of the smaller meshes for intersections with the main one, make a pre-determined adjustment to the position of the smaller mesh, and repeat as necessary until the intersection is gone (or until it has run 10 times).
If it can do all that without the system acting like it’s going to crash, I’ll be happy.
Denis showed a solution of this using Vol Select modifier.
Can you point me to it?
Here.
Another thread at scriptspot. There is a colision_detection.ms that will select the intersecting faces.
A ready to be used script – Volumetric Object Select.
