Abstract :
We present a method for computing normals and colors from multiple sets of photometric data that are consistent with each other and an underlying lower resolution mesh. Normals are computed by locally adjusting the light source intensities using data from the underlying mesh. Colors are derived from the photometric calculations, and are adjusted by a global color registration, analogous to global geometric registration
