Accurate thickness computation of a B-Rep model on the GPU
Résumé
In this paper, we present a technique that calculates the thickness of a B-Rep model.
This calculation is performed directly on trimmed NURBS and not on a triangular approximation.
We determine the thickness in parallel on GPU, by computing the radius of maximal spheres contained within the B-Rep model.
The results are presented by a color-coded thickness map. A detailed study of our results
demonstrates a very important gain in stability, precision and computation time compared to others approaches.
