IDLgrVolume

Superclasses | Creation | Properties | Methods | Version History

A volume object represents a mapping from a three-dimensional array of data to a three-dimensional array of voxel colors, which, when drawn, are projected to two dimensions.

An IDLgrVolume object is an atomic graphic object; it is one of the basic drawable elements of the IDL Object Graphics system, and it is not a container for other objects.
