OpenGL rendering and utility classes

---

The GL module incapsulates ROOT's interface to the OpenGL rendering engine and provides the following functionality:

• management of system-resources;
• frequently used utility classes;
• base-classes for shapes, scenes and viewers;
• concrete implementations of shapes needed by TGeo package;
• concrete implementations of scenes and viewers including the GUI components;
• specialized plot-painters for GL rendering of TH2, TH3, TF2 and TF3 object as well as parametric surfaces.

Papers describing OpenGL in ROOT:

• ROOT 3D graphics, presented at CHEP 2006.
• 3D graphics with OpenGL: recent improvements and plans, presented at ROOT Workshop 2007
• Next generation of OpenGL support in ROOT, presented at CHEP 2007.
