Abstract
A method of automatically generating lighting data for a three-dimensional computer generated entity is described. A mesh representation of at least a part of the entity is received and simplified by removing vertices from the mesh. For each vertex in the simplified mesh, a plurality of rays are propagated from the vertex and a cone-shaped region is then defined for the vertex using those of the plurality of rays that do not intersect with the simplified mesh, wherein the cone-shaped region is defined in terms of a vector and an angular parameter. An angular parameter and a vector for each vertex in the received mesh is then calculated by interpolating the angular parameters and vectors for each vertex in the simplified mesh and lighting data is output, the lighting data comprising the angular parameter and vector for each vertex in the received mesh.
