Abstract:


    Displacement Mapping [Cook 1984] is commonly used in commercial rendering software for adding surface detail. In contrast to Bump Mapping not only the normal is perturbed, the surface is modified as well. A given point P on a surface is displaced to a new point P’ in the direction of the surface normal of the point P, N scaled with the value stored in the Displacement Map:
