WebThe intersection of two k-DOP's can be computed very similarly to AABBs: for each orientation, you just check the two corresponding intervals of the two DOP's. So, just like DOP's being a generalization of AABBs, the intersection test is a generalization of the AABB overlap test. The complexity of the overlap test of two DOP's is in O(k). This ... WebA 3D frustum has 8 vertices and 6 planes. A 3D pyramid has 5 vertices and 5 planes (I use 6) That means we need 8 x 6 + 5 x 6 = 78 tests.
