<DRM Enclosing Volume>

Superclass

<DRM SEDRIS Abstract Base>

Subclass

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 <DRM Volume Extent> component.

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

¹The <DRM Location 3D> component specifies the volume centre.

²The <DRM Volume Extent> component specifies the volume shape.

Example(s)

A representation of a terrain region has a <DRM Bounding Volume> instance B defined by a sphere. B has a <DRM Spherical Volume Extent> component with its centre specified by the <DRM Location 3D> component of B and radius specified by the radius field of the <DRM Spherical Volume Extent> component.
A parallelepiped <DRM Collision Volume> instance describing collision space for a house has a <DRM Location 3D> component for the centre of the house and a <DRM Parallelepiped Volume Extent> component describing the boundary for the collision space.
