• Bounding Volume
• Collision Volume
• Sound Volume

Definition

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 Volume Extent component, the location of the shape center is given by the Location 3D component.

Example

1. A terrain region has a Bounding Volume defined by a sphere with center specified by the Location 3D component and radius given by the Spherical Volume Extent component radius field.
2. A parallelepiped Volume, describing the Collision Volume of a house, is represented by a component Location 3D for the center of the house and a component Parallelepiped Volume Extent.
