In this work we present a fast, efficient and robust algorithm to ray trace trimmed NURBS surfaces of arbitrary degree. Furthermore, our approach is largely independent of the number of control points of a surface with respect to the rendering performance.
A new method for speeding up ray tracing NURBS surfaces
https://www.sciencedirect.com/science/article/pii/S0097849397872639
The method proposed for speeding tip ray tracing NURBS surfaces can reduce both the iteration steps and arithmetic operations, thus much CPU time is saved. The new method is faster than the previous methods for which published …

Practical Ray Tracing of Trimmed NURBS Surfaces
https://www.cs.utah.edu/gdc/publications/papers/raynurbs.pdf
A system is presented for ray tracing trimmed NURBS surfaces. While approaches to components are drawn largely from existing literature, their combination within a single framework is novel. This paper also differs from prior work in that the details of an efficient implementation are fleshed out. Throughout, emphasis is placed on practical ...

Although ray tracing applications generate realistic images, and trimmed NURBS surface representation is common for computer aided design, they are not usually com- bined together. NURBS surfaces are not used as basic objects in ray tracing applica- tions, because finding ray-NURBS surface intersection is complex problem.
Accelerating Rendering of NURBS Surfaces by Using …
http://wscg.zcu.cz/WSCG2008/Papers_2008/short/F79-full.pdf
Obviously, ray tracing NURBS surfaces still can be considerably slower than ray tracing triangles. In order to further reduce the speed gap, we extended the existing system with a hybrid ray tracing module. This module will speed up the NURBS tracing process by completely avoiding acceleration data structure in- tersection tests for primary rays.
