You mustn=92t call SwapBuffer inside your glDraw implementation.=20
OnPaint method in CsGL.OpenGL.OpenGLControl class, triggers SwapBuffer =
by
you:

/// <summary>

Context.Grab();
glDraw();
GL.glFinish();
SwapBuffer();

Hi.
sorry for my english...
Nice work all, but i still have some trouble implementing double-buffer
(openGL and not forms).
I've written my control class, overriden OpenGLControl, and overriden
glDraw.
I'm using the screenSetting as Forms, and when i past this.swapBuffer() =
in
the overriden glDraw, my screen is flipping whit writting my openGL =
render
and a blank form.
does anyone can help me, before i go back to c++ :)=3D
i'll send you what shoold be in cause:
-------------------------------------------------------
class ctrl: OpenGLControl{
...
public override void glDraw(){
GL.glClear(...);
...
this.swapBuffer();
}
...
public void Main(){
CsGL.Util.screenSetting sf =3D new ...
ctrl c =3D new ctrl();
ctrl.Parent =3D sf;
Application.run(sf);
}
}
