cadcore-math

Fundamental math primitives for the cadcore CAD kernel.

Zero external dependencies. Everything in cadcore is built on top of this crate.

Types

Constants: EPS, PI, TAU.

Usage

[dependencies]
cadcore-math = "0.1"

use cadcore_math::{Point3, Vec3, UnitVec3, Mat3, Frame3};

// Build a right-handed frame from an origin and a Z axis
let origin = Point3::new(1.0, 2.0, 0.0);
let axis   = UnitVec3::try_from_vec(Vec3::new(0.0, 0.0, 1.0)).unwrap();
let frame  = Frame3::from_origin_z(origin, axis);

// Vector arithmetic
let a = Vec3::new(1.0, 0.0, 0.0);
let b = Vec3::new(0.0, 1.0, 0.0);
let c = a.cross(b);       // (0, 0, 1)
let d = a.dot(b);         // 0.0

// 3×3 rotation matrix
let rot = Mat3::rotation_z(std::f64::consts::FRAC_PI_2);  // 90° around Z
let v   = rot * Vec3::new(1.0, 0.0, 0.0);                 // (0, 1, 0)

// Interval utilities
use cadcore_math::Interval;
let i = Interval::new(0.0, 10.0);
assert!(i.contains(5.0));
let (lo, hi) = i.lerp_pair(0.25, 0.75);  // 2.5, 7.5

Part of cadcore

This crate is a building block. If you need the full kernel (sweep, STEP export), use the cadcore facade instead:
