NURBS utilities in Rust.
Currently, only NURBS curve evaluation is complete. The evaluation uses a naive version of the de Boor algorithm. With this, it's possible to evaluate the 3D coordinates of a NURBS curve at any parameter value.
NURBS can represent conics with floating-point precision. This image shows a tesselated NURBS circle on the left and an SVG circle on the right:
NURBS are a generalization of Bézier curves, so they can exactly represent any order of Bézier curve. The image below shows an SVG cubic Bézier with a loop on the right and a tesselated NURBS representation on the left:
The library uses the "Rhino" form of NURBS curves, where there are two fewer control points than in "traditional" NURBS.
