The anchor point (origin) of the bounding box in 3D space.
The lengths of the bounding box along the 'u', 'v', and 'n' (normal) axes.
The vector representing the local 'u' axis direction of the bounding box.
The vector representing the local 'v' axis direction of the bounding box.
Represents a 3D bounding box defined by an anchor point, two axis vectors, and lengths along three axes.
