Practical Ray Tracing of Trimmed NURBS Surfaces
https://www.cs.utah.edu/gdc/publications/papers/raynurbs.pdf
implementation in general ray tracing programs. 1 Introduction The modeling community has embraced trimmed NURBS as a primitive of choice. The result has been a rapid proliferation in the number of models utilizing this representation. At the same time, ray tracing has become a popular method for generating computer graphics images of geometric ...
Optimizing Ray Tracing of Trimmed NURBS Surfaces on …
https://onlinelibrary.wiley.com/doi/10.1111/cgf.14410
Ray tracing of NURBS surfaces has not been widely used in industry due to its computational complexity that hinders achieving real-time performance in practice. We propose novel methods achieving faster point location search needed by trimming in the context of ray tracing trimmed NURBS surfaces.
(PDF) Direct and fast ray tracing of NURBS surfaces
https://www.researchgate.net/publication/232644373_Direct_and_fast_ray_tracing_of_NURBS_surfaces
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 …
A new method for speeding up ray tracing NURBS surfaces
https://www.sciencedirect.com/science/article/pii/S0097849397872639
INTRODUCTION It is known that ray tracing is a time-consuming method for the generation of realistic pictures. Its history, theory and capabilities have been well documented [1]. In this section several topics involved in the paper are briefly outlined below. 1.1.

Real-Time Ray Tracing - API support for this area was announced in March 2018, too late for inclusion in the book, so we wrote an additional chapter about the subject as a whole. Its hyperlinked bibliography is available. …

In this paper, a new algorithm with extrapolation process for computing the ray/surface intersection is presented. Also, a ray is defined to be the intersection of two planes, which are non-orthogonal in general, in such a way that the number of multiplication operations is reduced.
NURBS, ray tracing, and radiosity.... [Archive] - Sharky Forums
https://www.sharkyforums.com/archive/index.php/t-80028.html
I wonder when, or maybe the better word would be IF, a graphics card for games would ever be designed around real time NURBS, ray tracing and radiosity rather than the scanline, matrix approach of current cards. Imagine the graphics possibilities in games that were based on a real time NURBS, raytracing, radiosity engine!!! That would be unbelieveable!

Real-Time Ray Tracing (too old to reply) Vasco Alexandre da Silva Costa 2015-02-19 05:14:44 UTC. Permalink. Hello, I was reading your mailing-list archives and noticed you guys are ... polygonal, NURBS, volumetric, etc), but you basically have it right. We do support Boolean combinations of any solid entity type against any other. This involves ...

NVIDIA's Real-Time Path Tracing Takes Ray Tracing Graphics …
https://www.techeblog.com/nvidia-real-time-path-tracing-raytracing-graphics/
There’s ray tracing, and then NVIDIa’s new path tracing, which is touted as of the largest breakthroughs for real-time graphics in many years. Put simply, this graphics technology is the most accurate way of rendering, but also computationally intensive due to the simulation of light/material interaction through many bounces.
