GPU Algorithms for NURBS Minimum Distance and Clearance Computations
Speakers:
Adarsh Krishnamurthy
- University of California, Berkeley
Abstract:
We present GPU algorithms and strategies for accelerating distance queries and clearance computations on models made of trimmed NURBS surfaces. We provide a generalized framework for using GPUs as co-processors in accelerating CAD operations. The accuracy of our algorithm is based on the model space precision, unlike earlier graphics algorithms that were based only on image space precision. Our algorithms are at least an order of magnitude faster and about two orders of magnitude more accurate than the commercial solid modeling kernel ACIS.
