Normal shader

A glass facade modeled with planar geometry and tempering distortions added with a normal shader

A normal shader alters the surface normal of a geometry, as a function of the original normal and shading parameters (UV coordinates, world-space position, etc...). For instance, it may be used to model small distortions over a glazing, without the need to distort the geometry.

This shader alters the surface normal based on a height field, given as a grey scale image.

This shader alters the surface normal based on an image giving the normal vector in tangent space coordinates.
