Caminhando Sobre Uma Interse C~ Ao De Superf Cies Com Passos Circulares

This paper presents an alternative way to calculate the next approximate point in marching techniques for the computation of the intersection of two parametric surfaces. Di ering from the classical methods, the algorithm is based on the approximate osculating circle instead of tangent vector to estimate the next point. It provides closer estimation and a larger marching step in each iteration with relatively low computational cost.
