## Abstract

The primary focus of this work is to experimentally explore a method for determining three dimensional surface shape from intensity information. A method is developed, using existent theory, for determining the shape of visually textured surfaces exhibiting varying degrees of specularity. The photometric~ is extended to four source photometry as the basis for this work. The reflectance map approach for determining surface normals is shown to be of 1 ittle value in this context and a more direct method of computing these normals is used.
