This may or may not be a simple question, how would i detect if a single triangle is intersecting a mesh? Preferably something cheap to process. At first i was thinking i could check if a point is within a range of a Dot product, but then i realized a mesh could intersect it without having a vertex inside the triangle, so that obviously wouldn’t work. I would simply use the default collision detection, but i want to cycle through certain triangles in a mesh to check for intersection.
I’m sure there are plenty of people out there who know the answer, so could someone give me a general idea of how i would achieve this?
