[size="4"]I want to make glass posteffect like in ogre demo.
Unfortunately I did find nothing. Maybe there are some papers or shaders.
Also, it is interensing to know the principle of this effect.

Glass effect (Ogre)
in this screen u see a simple refraction shader, it is really just simple phisics.
http://en.wikipedia.org/wiki/Refraction
What u need:
u probably don't need a perfect phisic simulation so u can cut some corners.
Just google for refraction shaders(like in water rendering)

What u need:
- surface normal(in,out)
- light direction
- thinkness of material
