Hi,
If I understand you correctly, I think what you are looking for is a
reflection. "Mirroring" in 3D doesn't seem to me to be a readily identifiable
concept. What I see is a 2D reflection of the 3D object based on my viewpoint
and the visual projection to that point. To reflect an object you multiply the
coordinates by an identity matrix where the diagonal element of the desired
reflection plane is set to -1 vice one. For example, to reflect an object
about the x-y plane (meaning z values are reversed) multiply by:
| 1 0 0 0 |
| 0 1 0 0 |
| 0 0 -1 0 |
| 0 0 0 1 |
Reflection about other planes is similar and of course you can build compound
reflections also.
Hope this points you in the right direction - Good luck - Gary Graf
