   Perspective with quadrics is backwards
  Well here is the other thing about OpenGL I'm baffled with.  Whenever I place quadrics into a scene the perspective with them only turns out backwards.  By that  I mean that instead of perspective lines converging in the distance, they spread out.  This causes the objects to appear larger the farther away from you they are.It seems as if the z dimension calculations are reversed.  Is this a bug or programmer error of some type?  It happens with all code examples I've every tried.Philip   
  Post code. Although it sounds a bit like a combination of incorrect backface colling settings and you expecting the Z-axis to go in the other direction. However, if it's only for quadrics and everything else works as expected, then I don't know without more information.   ;  Depth testing may also need to be enabled.
