Abstract

See full text

Light sources are simulated by using a surface normal perturbation method. A mesh representing the surface of an object and containing surface normals is provided. A light source vector representing the orientation of the surface toward a light source is generated. Based on light intensity adjustments input by a user, the surface normals are perturbed in a lighting equation to simulate a change in light intensity on the surface without rotating the surfaces relative to the scene.
