I currently setup gl for 2D this way: I tried to setup it for 3D.. but no vertices are rendered! What is wrong?! Thank you very much for your help!(: Riddle
Gl.glViewport( 0, 0, screen_w, screen_h );
Gl.glMatrixMode( Gl.GL_PROJECTION );
Gl.glLoadIdentity();
Gl.glOrtho( 0, screen_w, screen_h, 0, -1.0, 1.0 );
Gl.glMatrixMode( Gl.GL_MODELVIEW );
Gl.glLoadIdentity();
Gl.glClearColor( 0.0f, 0.0f, 0.0f, 0.0f );
Gl.glViewport( 0, 0, _window.Width, _window.Height );
Gl.glMatrixMode( Gl.GL_PROJECTION );
Gl.glLoadIdentity();
Gl.glMatrixMode( Gl.GL_MODELVIEW );
Gl.glLoadIdentity();
Gl.glClearColor( 0.0f, 0.0f, 0.0f, 0.0f );
Gl.glClearDepth( 1.0d );
Gl.glEnable( Gl.GL_DEPTH_TEST );
Gl.glDepthFunc( Gl.GL_LEQUAL );
Gl.glHint( Gl.GL_PERSPECTIVE_CORRECTION_HINT, Gl.GL_NICEST );
