Overview

Format-neutral algorithms over polynomial and rational B-spline curves and surfaces: differential geometry, exact shape-preserving transforms (knot insertion, reversal, splitting, Bezier decomposition, degree elevation), tolerance-bounded knot removal and degree reduction, interpolation and lofting, certified projection, inversion and intersection queries, exact analytic curve and surface intersection, and verified periodic seams. Lossy operations measure their deviation and refuse above the caller's tolerance. It owns no importer, tessellator or file-format vocabulary, and it uses axiolid-evaluate for evaluation rather than reimplementing it.
