3D Graphic
The Graphic3d package lets you create 3d graphic objects in a viewer. These objects, called structures, are made up of groups of primitives and attributes. A group is the smallest editable element of a structure. A structure can be displayed, erased, and highlighted. A transformation can be applied to it. Structures can be connected to form a hierarchy of structures, composed by transformations. The viewer can perform global manipulation of structures.
The Visual3d package contains the group of classes required to implement commands for a 3D viewer. The viewer manages views and light sources.
