Example
The rectangular <Bounding Volume> instance of a
house that is used to show the maximum extents of the house in three
dimensions. This may be used to calculate first level ray-volume
intersections.
FAQs
-
Can the <Bounding Volume> component and
<Collision Volume> component of
an <Aggregate Geometry> instance be the same?
Yes.
-
Can the <Bounding Volume> component and
<Collision Volume> component of
an <Aggregate Geometry> instance be different?
Yes.
-
Is the <Bounding Volume> component the
convex hull of the
<Aggregate Geometry> instance?
Not necessarily. The convex hull could be considerably more complex
than the <Bounding Volume> instance.
-
Does the <Bounding Volume> component
exactly contain the
<Aggregate Geometry> instance?
In special cases, the <Bounding Volume>
component may fail to contain all of the geometry due to
distortion introduced by coordinate conversion or transformation.
