## OpenGL tools

renderingMode — Controls the way OpenGL renders objects.
light — Controls the use of lights in the rendering window.
text — Enables capabilities to write some text on rendering screen.
view — Defines all necessary informations for the rendering of a view.
interactive — Gives tools to interact with the rendered area.
objectList — Gives storage for ids used by OpenGL lists and provides primitive routine for common drawing operations (distances, torus...).

These little utilities are dealing with OpenGL. They are not essential to V_Sim but can add some nice features that can be shared between different modules.
