react-three-nurbs/dist/hooks/useControlPointDrag.d.ts

A React component library for NURBS (Non-Uniform Rational B-Spline) curves, surfaces, and solids in Three.js. Built with React Three Fiber, zero external NURBS dependencies — all math implemented from scratch. Boolean operations powered by OpenCASCADE WAS
