i want to know how to make an effect as follow: make a mirror at the center of the scene,and leave a object(such as cube.etc.)at one side of the mirror,then i can move the camera,and when the camera stands in front of the mirror(the side of the object left in the scene),i can see the shadow of the object which is showed by the mirror. i know a way to make specular effects of slippy surface.that is: make another objects which is symmetric to this one,and place it to the another side of the slippy surface at an equal distance with the distance between the first object with the slippy surface,and then use the alpha blending to make people wrong impression that is like the specular effect. but it''s limited,because if the camera is moved to back of the mirror,u will the truth:a symmetric object is on the other side. So,is there a better way to make a more real mirror specular effect? thanks jerry2 Programming,make a whole new world.

The symetric method works, but its rather inefficient, yes ?
Check out NeHe`s tutrials.

i know.but what''s the efficient way of urs?

i can give you a general algorithimn for totally realistic mirroed textures.
But i doubt its real-time-able.
NeHe has a tutorial on it. There are probably a slew of other tutorals out there that i dont know of.
Personally im not interested a great deal, I`m not really interesed in the latest/greates 3d engine.
So go search.
