Hello I would like to find out that which one and why one of these is better than another: Scenario: Imagine I have two or more objects and each object has lots of triangles, these objects could be deformable or solid (static). I want to do collision detection between these objects but I am not sure which one is the best way for real time animation (I need to implement the collision in 2 days). 1- divide the space into boxes and then do the collision only between those triangles that are in that space area (Box). if I do this then I have to reallocate triangles to each box. 2- use bounding box from beginning of animation. meaning I allocate set of triangles (neighboring ones) to each bounding box or sphere for each object and then check those bounding volumes and if they collide, check the collision between triangle and triangle. Is there any more ways ? it needs to be fast and not very difficult (rocket science). Thank you for you help. Thanks in advance.
