On ray tracing parametric surfaces

Web14 de out. de 2016 · In this paper, we present a novel geometric method for efficiently and robustly computing intersections between a ray and a triangular Bézier patch defined over a triangular domain, called the hybrid clipping (HC) algorithm. If the ray pierces the patch only once, we locate the parametric value of the intersection to a smaller triangular domain, … WebAbstract. This paper presents a new approach for ray tracing parametric surfaces. Instead of performing the computations in object space, the intersection search is more efficiently …

WebTo intersect a ray with this surface, you have to find the roots of a polynomial of degree 18. There is no formula for these roots -- you have to find them by numerical methods. In fact, there are mathematical results ( the Abel-Ruffini theorem) telling us that there can never be formulae for roots of equations beyond degree 4.
