The 3D view class.
This package was originally written by Evgueni Tcherniaev from IHEP/Protvino.
The original Fortran implementation was adapted to HIGZ/PAW by Olivier Couet and Evgueni Tcherniaev.
This View class is a subset of the original system. It has been converted to a C++ class by Rene Brun.
TView3D creates a 3-D view in the current pad. In this 3D view Lego and Surface plots can be drawn and also 3D polyline and markers. Most of the time a TView3D is created automatically when a 3D object needs to be painted in a pad (for instance a Lego or a Surface plot).
In some case a TView3D should be explicitly. For instance to paint a 3D simple scene composed of simple objects like polylines and polymarkers. The following macro gives an example:
Several coordinate systems are available:
