Screen-space distortion

Add Comment! By David Rosen on March 12th, 2006

We can now apply distortion effects to anything; in this screenshot I applied a basic refraction shader to the player model! Screen-space distortion is much faster than cube map distortion, because we do not have to render the scene extra times.

This effect will be used for heat haze, water refraction, fire distortion, and so on.
