Each plane needs to be tracked against three vertices, this gives sixty values to track. 3 This method is called a posteriori because it typically misses the actual instant of collision, and only catches the collision after it has actually happened. 2 2 At the coarse level of collision detection, the objective is to find pairs of objects which might potentially intersect. 1 (for simplicity, we will assume that each set has the same number of triangles.). i {\displaystyle I_{k}} ) j In addition to the a posteriori and a priori distinction, almost all modern collision detection algorithms are broken into a hierarchy of algorithms. {\displaystyle \mathbb {R} ^{3}} A m R E At each simulation step, a list of all intersecting bodies is created, and the positions and trajectories of these objects are somehow "fixed" to account for the collision.
