BoundingVolume
from panda3d.core import BoundingVolume
- class BoundingVolume
Bases:
TypedReferenceCountThis is an abstract class for any volume in any sense which can be said to define the locality of reference of a node in a graph, along with all of its descendants. It is not necessarily a geometric volume (although see GeometricBoundingVolume); this is simply an abstract interface for bounds of any sort.

Any kind of volume might be empty. This is a degenerate volume that
contains no points; it’s not the same as, for instance, a sphere with
radius zero, since that contains one point (the center). It intersects
with no other volumes.

- isInfinite()
C++ Interface: is_infinite(BoundingVolume self)
- /**
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.
