The culmination of a rapidly changing AABB

"The culmination of a fast-changing AABB "

When changing a AABB, you can quickly calculate the aabb of the vertex after the change. When there is a rotation, the AABB may be larger depending on the 8 vertices.

　　

The eight vertices of the aabb need to be transformed as follows:

　　

Note that in order to make X ' Minimum, the m11x, m21y, m31z must be minimized. Assuming that the mxx are greater than 0, you need to take x, Y, z the largest top, such a point is certainly the vertex of AABB. So the fast method of calculation is to take the extremum of X, Y and z directly.
