Detailed Description

An OpenGL renderer for various GEE objects.

About particle rendering: Particles are a pain to render. They must be rendered as billboards that are in the world coordinates. The user may how-ever apply any transformation before we get to rendering the particles. These transformations must be undone if we are to get the particle alignments correct. For this reason we must take copy of the modelview matrix before we do any OpenGL matrix operations. When rendering particles the matrix in the stack is replaced with the original modelview matrix. Then everything is ok again.

GEE_GlRenderer::ListMode GEE_GlRenderer::renderDisplayList (  GEE_Geometry *  g  )  [protected]

Checks if there is a diplay list for this graphic. If there is no list storage, then no list-related stuff is done and NO_LIST is returned. If the list exists, then it is rendered. If the the list does not exist, but there is a list storage, then its recording is began.
