Erratum: A Precision Controlled Surface-Surface Intersection Algorithm for NURBS

ACM Graphics has published an erratum for a precision-controlled surface-surface intersection algorithm for NURBS, a niche but important topic for high-end geometry work. For teams building CAD-like tools, procedural modeling, …

A Texture Lookup Approach to Bézier Curve Evaluation on the GPU

GPU curve evaluation just got a hardware-assisted twist: a texture-lookup method uses fixed-function linear interpolation to evaluate Bézier curves faster in compute-bound workloads. The same idea extends to Bézier surfaces, …

A Precision Controlled Surface-Surface Intersection Algorithm for NURBS

A new ACM TOG paper tackles one of the nastier CAD-to-runtime problems: robust NURBS surface-surface intersection. The focus is precision control, which matters when tiny numerical errors can wreck trimming, …

Spatially Accelerated Winding Numbers for Curved Geometry

Curved CAD-style geometry is finally getting a faster containment test: this paper extends generalized winding numbers to NURBS curves and trimmed NURBS patches without falling back to triangle-only approximations. The …

Explicit Inversion of Planar NURBS Curves

The recent paper on planar NURBS curves introduces a method for explicitly inverting these curves using rational splines. This breakthrough is particularly relevant for graphics programmers and designers, as it …
