Abstract
A method for modeling an object with a polygonal mesh includes obtaining a closed-surface polygonal mesh and positioning the closed-surface polygonal mesh relative to the object. A ray is projected through a point-of-interest on said closed-surface polygonal mesh. The existence of an intersection point between said ray and a surface of the object is determined and the location of the point-of-interest is adjusted in response to the existence and location of the intersection point. The projecting is repeated for a plurality of points in the closed-surface polygonal mesh in order to approximate the object.
