I understand that when opengl is activated that p_GDIFunction is no longer called. Is there any way to do custom graphics when use of opengl is enabled? Would it be possible to add a hook, similar to p_GDIFunction, that would call an ACSIL user code function after you have rendered the current graph but before the buffer is swapped. Wouldn't such a call allow user code to draw anything onto the back buffer with normal gl calls? It is a shame to have the huge improvement of using opengl available but not be able to use it because of the need to support custom graphics. Thanks |

Yes if you know what you are doing: Wouldn't such a call allow user code to draw anything onto the back buffer with normal gl calls?

Any chance that such a hook could be added? I would be happy to test it out. I was able to use opengl through p_GDIFunction in the past but all ability to draw custom graphics goes away when one turns on opengl in SC. Thanks. |
