1. A method of processing a set of meshes, each mesh comprising data points representative of a corresponding surface, the method comprising the step of: generating consistent parameterizations for the meshes, the consistent parameterizations each having substantially the same base domain for at least a portion of the corresponding mesh; wherein the generating step utilizes a net tracing algorithm which involves determining for each of the meshes a net of paths having a connectivity substantially the same as that of the base domain within at least the portion of the corresponding mesh.
