//! Geometry foundation for SolidCraft: 2D/3D vectors, sketch planes, axis-aligned boxes,
|
|
//! triangle meshes with their measures (volume, area, centroid), and freeform surface maths
|
|
//! (B-spline basis and NURBS surfaces in [`bspline`], one-surface fills of closed loops in
|
|
//! [`fill`], T-splines in [`tspline`]). Units are millimetres.
|
|
//!
|
|
//! This crate has no knowledge of sketches, documents or a modelling backend; every other crate
|
|
//! builds on it.
