We investigate the problem of determining visible regions i n two or three dimensional space given a set of obstacles and a moving vanta ge point. This is of importance in several fields of study including renderi ng n computer graphics, etching in materials construction, and navigati on. Our approach to this problem is through an implicit framework, where the o bstacles are represented by a level set function. An efficient generic mul tiscale level set method is developed to generate the… CONTINUE READING
