Hi NinjaCross,
That a pretty interresting subject, i''had think alot about mirror surface (texture).
In real life, a mirror reflect light with the same angle as received light.
''\'' is the light
''/'' is the reflected light
''/'' is the normal of the plane
a = b; that''s always true !!!
So, using those law of light. I thought, why not trace a ray to the middle of the reflecting plane, that will give us a ray that goes where the light is coming to our eyes. So i thought using another camera behind the mirror (the camera is positionned on the projected vertex), and use the mirror as a clipping plane (frustum clipping).
But, maybe the speed will not be very high, anyway their other way i was thinking implementing mirror surface. But this give some basic. Thought around that, you will figure.
Here a clue, take a mirror. Put it in front of your, And turn around !!!! And analyze what is going on.
Good Luck, Happy Coding ...

well, if you''re using portals, it''s pretty trivial. a mirror is just like a portal, but instead of extending the view into the next room or sector, it reflects it back into the current one. same math, same concepts.

Hey, I didn''t talk about Unreal
Anyway, I don''t like Unreal, even if it''s a good game :o)
I mean, the direct3D version doesn''t work and the OpenGl looks like half a frame per second ... (I don''t understand that !!)
Anyway, I played it over to a friend, it''s a good game... and no, I never looked into the unreal wads
