| A displacement shader is one of four component shaders used to define an RH_MATERIAL. A displacement shader simulates the effects of small surface perturbations by modifying the surface normal vector that is applied to subsequent shading calculations. Also known as bump mapping, it provides visual effects such as roughness or undulations that are difficult or expensive to model discretely. | |||||
