Detailed Description

The ViewBase class using OpenGL for drawing.

Attention:: This class was contributed by its author as an experiment to evaluate the core library classes with OpenGL. The author reports: "Now the plotting is very close to what you have with Qt drawing lib." This class and others in this directory require CMT for its build.
