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.
