Abstract Class Name: Enclosing Volume

Superclass - <SEDRIS Abstract Base>

Subclasses

• <Bounding Volume>
• <Collision Volume>
• <Sound Volume>

Definition

An instance of this DRM class is a geometric primitive shape that identifies an enclosed space. Possible shapes include spheres (and implied points, where a point is a degenerate sphere), parallelepipeds, cylinders (and implied lines, where a line is a degenerate cylinder).

The shape is specified by the <Volume Extent> component.

The location of the shape centre is specified by the <Location 3D> component.

Example

1. A representation of a terrain region has a <Bounding Volume> instance B defined by a sphere. B has a <Spherical Volume Extent> component with its centre specified by the <Location 3D> component of B and radius specified by the radius field of the <Spherical Volume Extent> component.

2. A parallelepiped <Collision Volume> instance describing collision space for a house has a <Location 3D> component for the centre of the house and a <Parallelepiped Volume Extent> component describing the boundary for the collision space.
