WebNov 12, 2013 · This is repeated over and over, so the algorithm essentially expands the simplex inside the Minkowski Sum. Once the distance between v and the support point is less than a certain threshold, we have found the penetration depth, and can easily determine the contact point and normal. The only issue I'm having with EPA is the subdivision of the ...

WebMar 24, 2024 · However, once GJK detects a collision, what do we do next? Often, we want to translate one of the objects so that there is no longer a collision. Well, one way that to calculate this translation vector that I saw commonly mentioned in various threads is called the Expanding Polytope Algorithm (EPA).
