Crate mesh_geometry

mesh-geometry

High-performance, no_std-compatible geometry primitives and metrics for spatially discrete meshes.

Features

• Core types: Point2, Point3, Vec2, Vec3 with arithmetic, dot/cross, and conversion utilities.
• Cell metrics: triangle/quad area, centroids, tetrahedron/hexahedron volume, face normals, projected area.
• Geometry queries: point-in-polygon, ray-triangle intersection, point-to-cell distance.
• Advanced utilities: Jacobians, AABB, 3D affine transforms.
• no_std compatible (default: std enabled).
• Comprehensive documentation and examples.

Example: Compute Cell Volumes

use mesh_geometry::{Point3};
use mesh_geometry::tetrahedron_volume;

let a = Point3::new(0.0, 0.0, 0.0);
let b = Point3::new(1.0, 0.0, 0.0);
let c = Point3::new(0.0, 1.0, 0.0);
let d = Point3::new(0.0, 0.0, 1.0);
let vol = tetrahedron_volume(a, b, c, d);
assert!((vol - 1.0_f64/6.0_f64).abs() < 1e-12_f64);
