Hi i have a scene where the object closest to the viewer gets at certain angles objects appear to disappear also obscure the view of other objects when they should not - i.e they are draw in front of or behind other objects when it should be the opposite also the also disappear at certain angles I have the following in my initOGL() glShadeModel(GL_SMOOTH); glCullFace (GL_BACK); glEnable( GL_DEPTH_TEST ); // Enables Depth Testing glEnable (GL_LINE_SMOOTH);//makes grids on floor look smooth glEnable (GL_POLYGON_SMOOTH); glEnable (GL_CULL_FACE); and in onPaint() i have glDepthFunc(GL_EQUAL); // The Type Of Depth Testing To Do glClearDepth( 1.0f ); // Set Depth Buffer to Max Dist. when cleared glClearColor( 0.0f,0.0f,0.0f,0.0f ); // Black Background glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); any ideas?

You probably want to use GL_LEQUAL not GL_EQUAL in your depth function.

See if that helps.
