What is AABB – Collision detection?

by

AABB stands for “Axis-Aligned Bounding Box.” It is a fairly computationally- and memory-efficient way of representing a volume, typically used to see if two objects might be touching. Since it is axis-aligned, it does not necessarily “fit” your real 3D object very well. AABB checks are often used as a coarse first-approximation to see if … Read more

Rotate image and crop out black borders

The math behind this solution/implementation is equivalent to this solution of an analagous question, but the formulas are simplified and avoid singularities. This is python code with the same interface as largest_rotated_rect from the other solution, but giving a bigger area in almost all cases (always the proven optimum): def rotatedRectWithMaxArea(w, h, angle): “”” Given … Read more
