Collision Query between Moving AABB and AABB

Explains how to find the time of impact between a moving AABB and stationary AABB using the SAT (Seperating Axis Theorem). Also works with two moving AABBs, since you can simply subtract the velocity of one AABB from the other's to make it stationary.

Static Intersection Test Between Cylinder and Sphere

Shows how to do an intersection check between a freely oriented cylinder and a sphere

Static Intersection Test Between OBB and Sphere

Explains how to check an OBB (oriented bounding box) for intersection with a sphere.

Static Intersection Test Between OBB and OBB

Explains how to determine whether two freely placed OBBs (oriented bounding boxes) are overlapping with each other.

Static Intersection Test Between AABB and OBB

Explains how to determine wether an AABB (axis-aligned bounding box) is overlapping with an OBB (oriented bounding box)

Static Intersection Test Between AABB and Sphere

Shows how to determine whether an AABB (axis-aligned bounding box) is intersecting with a sphere

Static Intersection Test Between Sphere and Sphere

Explains how to determine whether two non-moving spheres intersect each other.

Static Intersection Test Between AABB and AABB

Explains how to perform a simple intersection test on two stationary AABBs (axis-aligned bounding boxes).
