Definition |
This is an abstract DRM class that specifies a geometric primitive shape that identifies an enclosed 3D solid. Possible shapes include spheres (and implied points, where a point is a degenerate sphere), parallelepiped, cylinders (and implied lines, where a line is a degenerate cylinder). The shape is given by the <DRM Volume Extent> component, the location of the shape center is given by the <DRM Location 3D> component. |
||||||
|
Example(s) |
· A terrain region has a <DRM Bounding Volume> defined by a sphere with center specified by the <DRM Location 3D> component and radius given by the <DRM Spherical Volume Extent> component radius field. · A parallelepiped <DRM Volume>, describing the <DRM Collision Volume> of a house, is represented by a component <DRM Location 3D> for the center of the house and a component <DRM Parallelepiped Volume Extent>. |
