Jord — Singularity-free 3D spherical geometry, navigation and kinematics

Title: [Showcase] jord — Singularity-free, vector-based 3D spherical navigation Hi everyone! I'd like to share jord, a pure Rust crate for 3D spherical geometry, geodesy, navigation and kinematics. Why jord? Standard latitude/longitude calculations suffer from singularities at the poles, discontinuities across the anti-meridian, and heavy trigonometric CPU overhead. jord implements Kenneth Gade’s n-vector representation, replacing spherical trigonometry with 3D linear algebra: Singularity-...
