Detailed Description

Plot3D handles all the common features for plotting widgets beyond the low-level extensions of ExtGLWidget - coordinate system, labeling and more. It contains some pure virtual functions and is - in this respect - an abstract base class. It's nevertheless no pure interface. The class provides interfaces for basic data controlled color allocation.
