Example

1. 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 an <Aggregate Geometry> instance's <Bounding Volume> component and <Collision Volume> component be the same?

Yes.

Can an <Aggregate Geometry> instance's <Bounding Volume> component and <Collision Volume> component 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.
