Detailed Description

template<typename T>
class vmml::AABB< T >

An axis-aligned bounding box.

An empty bounding box has undefined, implementation-specific values. Read operations (getMin(), getMax(), getSize(), isIn(), etc.) have undefined semantics on an empty bounding box. set() and merge() operations will define the bounding box correctly.
