"Witryna24 kwi 2009 · To test collision detections between 2 oriented bounding boxes, I'd use separating axis theorem ( SAT ). In fact SAT can be used for collision detection between any 2 convex shapes. This technique is not overly complex to understand and has a reasonable performance. The theorem can easily be extended to 3D. EDIT: " - Oriented bounding box collision

WitrynaIn this paper we address the problem of collision detection and response in real-time animation systems. We describe an approach, which approximates objects using sphere-trees, and uses an interruptible detection algorithm to approximately test for collisions between them, trading accuracy for speed.

Witryna23 lut 2024 · As with 2D collision detection, axis-aligned bounding boxes (AABB) are the quickest algorithm to determine whether the two game entities are overlapping or not. This consists of wrapping game entities in a non-rotated (thus axis-aligned) box and checking the positions of these boxes in the 3D coordinate space to see if they … Witryna20 wrz 2015 · The way I was thinking of doing collision was by having each bone on the mesh have a bounding box, which would each move along with the bone's matrix. For example: link . It seems to be faster than having to do trimesh collision, especially if the mesh is going to have skeletal animation.

Up to now, the most effective has probably been the one based on AABB trees (cited in section 2.2). This ap-proach, like our one, uses a hierarchy of bounding boxes: it proceeds recursively, starting from the bounding box of the whole object and partitioning the primitives into …
