Refraction

Author: Aras Pranckevicius

Description
Similar to the Glass shaders in Pro Standard Assets, but this refracts based on actual geometry (whereas Glass uses only a normal map). This is not true refraction, only something that distorts the image in a way that looks remotely like refraction :)

Works on vertex/fragment program capable hardware (Radeon 9500, GeForceFX, Intel 9xx). Requires Unity Pro.
