3D graphics classes

TGraphicHierarchy3D: Parent to TGraphicGroup. TGraphicGroup lets you create a hierarchy of references to a collection of 3D graphics. The hierarchy can be treated as one unit, or you can have access to any graphic or group of graphics at any point within the hierarchy.

TLine3D, TCurve3D, TPolyline3D, and TSurface3D: The 3D graphics classes.

The sweep classes are shown in Figure 8. They are used for creating a swept surface in 3D space. TSurface3D implements the same kinds of shapes as TSweep3D, but you must understand more about creating common quadratic shapes when you use TSurface3D. TSampledSurface3D (not shown because it does not descend from MGraphic3D) lets you divide a 3-D surface into discrete points called shards to model such things as fractal surfaces, digitized data, and shapes approximated from other computations such as fluid flow.
