In this paper we propose a technique for computing the ray caustic distance parameter on an arbitrary convex surface described by Non-Uniform Rational B-splines (NURBS) surface representation. The ray caustic distance parameter is essential for evaluating the UTD surface diffracted fields that are diffracted from a convex surface. Examples validating the accuracy of the numerical approach proposed are presented.
