1 This specifies the volume centre.

2 This specifies the volume shape.

Example(s)

  • The cylinder that describes the gun tube of a weapon system.

  • Consider a geometric representation of a car, for which it will be necessary to compute intersections of the front of the car with other objects. In this example, the data provider constructs a perpendicular volume projecting from the front bumper of the car representation, and uses the resulting <DRM Parallelepiped Volume Extent> to specify a <DRM Collision Volume> for the car representation.
