WebAABB-to-OBB. Testing if an AABB and an OBB overlap can be done using the Separating Axis Theorem ( SAT ). This test will require a total of 15 axes to be tested. Chapter 5, 2D Collisions, provides an in-depth explanation of how the SAT works. The 15 axes of potential separation are: The three axes of the AABB (world X, Y, and Z) The three axes ... WebThis is possible with the technique called frustum culling! We will be learning how to check if an objects AABB (Axis-Aligned Bounding Box) is within the cameras view, and if it isn't, we will not send it to the GPU, easy as that! I say "CPU Side Frustum Culling" because the GPU actually does frustum culling for us.
