Backface highlighting

Hi,

I have to be very pecise about normal directions for game programming, It's always a lot of work getting normals corrected after work - don't know why they are not correct btw, but that might be my fault.
The normal vertices are sometimes a bit difficult if you have slim objects, the normals of the oppositing surfaces point out, making it look as if it were good.

Now, if you could offer a more, where you draw only the front faces (GL_FACE_CULL), and then draw all the backfaces, with inverted material color, it would be very obvous to see which triangles are still wrong order. Do you know what I mean? Could you implement such a mode?

Best regards,
Gernot
