Detailed Description

This defines a bounding convex hexahedron.

It is typically used to represent a frustum, but may represent any enclosing convex hexahedron.

This class does not support any of the around() or extend_by() functions, but all other functionality should be well-defined.

INLINE_MATHUTIL bool BoundingVolume::is_infinite ( ) const [inherited]

The other side of the empty coin is an infinite volume.
This is a degenerate state of a normally finite volume that contains all points. (Note that some kinds of infinite bounding volumes, like binary separating planes, do not contain all points and thus correctly return is_infinite() == false, even though they are technically infinite. This is a special case of the word 'infinite' meaning the volume covers all points in space.)
It completely intersects with all other volumes except empty volumes.

int ReferenceCount::ref ( ) const [inline, inherited]

Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is the new reference count.

int ReferenceCount::unref ( ) const [inline, inherited]

Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
