I downloaded the demo "Monsters" at glasm.ru in which TGLDirectOpenGL is used, got curious, looked at the source code in GLScene.pas (version 1.1 August 2010) and found this description:
"Provides a way to issue direct OpenGL calls during the rendering.
You can use this object to do your specific rendering task in its OnRender
event. The OpenGL calls shall restore the OpenGL states they found when
entering, or exclusively use the GLMisc utility functions to alter the
states."
Could someone please suggest some typical use case of this component and how is it different from what you normally do in the GLCadencer's OnProgress event? Sorry if the question sounds stupid but I'm in the process of evaluating GLScene for some fun.
Many thanks in advance!
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
