Detailed Description

Represents an axis-aligned bounding box (AABB) collision volume.

The CollisionVolumeAABB class implements an axis-aligned bounding box for collision detection. An AABB is a rectangular box aligned with the world axes, defined by its minimum and maximum corner points. This class provides methods to compute the AABB from a model and transformation matrix, retrieve its properties, and perform intersection tests with other collision volumes.

Typical usage involves calling ComputeData() to initialize the AABB from a model and world matrix, then using intersection methods for collision queries.
