   Thanks for the tutorial, unfortunately it does not work for me. All I see is white background with a red cross of which I don't know where it comes from... Thanks for any help...

   Strange, I've added a menu in the top of the window and now everything works perfectly :) thx for the tutorial. Without it I would never start. We Polish used to say "The first step is the hardest"

   the solution i know is:

       CheckForIllegalCrossThreadCalls = false;
   

   which is simpler

   private void OpenGL_Start() { if( this.view.InvokeRequired) { ThreadStart aDelegate = new ThreadStart(this.view.Refresh); for( ; ; ) { Thread.Sleep(1000); if( !thrOpenGL.IsAlive ) return; this.Invoke(aDelegate); } } else { for( ; ; ) { // infinity loop for rendering Thread.Sleep(1000); this.view.Refresh(); } } }

   (sorry for not marking the code as code in the comment above...)

   Hi Johnny, Still there? I know it's been a while since 2003... But if you are still around, or anyone else, I have a question:

   How do I draw two separate sets of drawing in parallel? I want to draw an Anaglyph. Let's say, a blue cube and a red cude. each in a different color and at a slightly different angle acording to two POV (points of view).

   Any suggestions?

   All the best. Amir

   Hi All, I ran into some trouble with the thread above, but, I found a solution... Aperantly, while using Visual Studio 2008 such a cross thread action is considered unsafe. Anyway, the "Invoke" method can take care of that with just a few lines of code:

   private void OpenGL_Start() { if( this.view.InvokeRequired) { ThreadStart aDelegate = new ThreadStart(this.view.Refresh); for( ; ; ) { Thread.Sleep(1000); if( !thrOpenGL.IsAlive ) return; this.Invoke(aDelegate); } } else { for( ; ; ) { // infinity loop for rendering Thread.Sleep(1000); this.view.Refresh(); } } }

   The 'if' statement check to see if the action is done on the current thread or not and uses the "invoke" when necessary.

   I hope I saved someone the 60 minutes it took me... ;-)
