This defines a bounding convex hexahedron.
It is typically used to represent a frustum, but may represent any enclosing convex hexahedron, including simple boxes. However, if all you want is an axis-aligned bounding box, you may be better off with the simpler BoundingBox class.

bool BoundingVolume::is_infinite | ( | ) | const [inline, 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.

void ReferenceCount::local_object | ( | ) | [inline, inherited] |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.
This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void 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.

bool ReferenceCount::unref | ( | ) | const [inline, virtual, 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.) 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.
The return value is true if the new reference count is nonzero, false if it is zero.
