WebAn axis-aligned bounding box, or AABB for short, is a box aligned with coordinate axes and fully enclosing some object. Because the box is never rotated with respect to the … WebApr 17, 2016 · You'll get your transformed AABB (in world space). It it most probably rotated (not axis-aligned anymore). Now your algorithm probably only work with axis-aligned stuff, hence your question. So now you approximate the new bounding box of the transformed model by takinf the bounding box of the transformed bounding box: WebA bounding box is a cuboid, or in 2-D a rectangle, containing the object. In dynamical simulation, bounding boxes are preferred to other shapes of bounding volume such as bounding spheres or cylinders for objects that are roughly cuboid in shape when the intersection test needs to be fairly accurate. long-throw woofer
