A system and method for generating new appearances of an object from a plurality of pre-defined appearances. The invention applies to a plurality of attributes for each appearance. A user may interactively specify a proportion (or weight) in which each of the pre-defined appearances is to be combined to generate a new appearance. An embodiment of the present invention then combines the attributes of the pre-defined appearances according to the respective weights to generate a new appearance. The present invention may be used to generate new expressions of a face by using pre-defined expressions such as an angry face, a happy face, a surprised face, and a sleepy face. Position and color attributes may be morphed efficiently and quickly. According to further enhancements, texture and the surface normal vector may also be morphed efficiently and quickly, even at real time frame rates. The present invention is also used to emulate or approximate representative lighting from several light source on the look of an area.
