Represents an axis aligned bounding box.

An axis-aligned bounding box, or AABB for short, is a box aligned with coordinate axes and fully enclosing some object. Because the box is never rotated with respect to the axes, it can be defined by just its center and extents, or alternatively by min and max points.

Bounds is used by Collider.bounds, Mesh.bounds and Renderer.bounds.


centerThe center of the bounding box.
extentsThe extents of the Bounding Box. This is always half of the size of the Bounds.
maxThe maximal point of the box. This is always equal to center+extents.
minThe minimal point of the box. This is always equal to center-extents.
sizeThe total size of the box. This is always twice as large as the extents.


BoundsCreates a new Bounds.

Public Functions
