Immediate mode rendering

Hi all,

I have a theoretical question: is it possible forcing a redraw for an AIS_Interactive object after each mouse move without using the HLR mode?
I want try to implement a kind of view dependent simplification for my shapes and to avoid creation of displaylists for each frame!

Does OCC utilize OpenGL display list? Some guys from OCC said they want but hadn't incorporate this powerful feature yet.

Since version 5.0 OCC does use the OpenGl display lists to increase the performance of certain operations. This fact was not reflected in the OCC descriptive documents since it was a preliminary integration, not completed with the usage example.
Such usage example will appear in the next OCC release coming soon.
