Abstract

The visual hull is widely used to produce three dimensional models from multiple views, due to the reliability of the resulting surface. This paper presents a novel method for efficiently evaluating the exact view-dependent visual hull without using approximations. Methods for selecting intersections and ordering them via the cross ratio are presented. Results show the high quality of the surfaces produced using this method.
