Detailed Description

This effect makes surfaces appear bumpy. Children nodes must use two textures, one for diffuse color and one for the normal map (which can be created from a height map with tools like nVIDIA's normal map generator). Furthermore, tangent-space basis vectors must be created and assigned to each Geometry; this can be done quickly by calling BumpMapping::prepareChildren(). Note that both diffuse and normal map textures must have corresponding UV maps defined in Geometry objects. This effect defines a preferred technique which uses ARB vertex & fragment programs, and a fallback technique which doesn't use fragment programs. The latter is more limited though since it can't handle ambient and specular components.
