- Abstract:
-
We present an alternative way to calculate the next aproximate
point in marching technique for the computation of the intersection of
two parametric surfaces. Differing from the classical methods, our algorithm
is based on an aproximate 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.
