manifold3d

Safe Rust bindings to the manifold3d geometry kernel for constructive solid geometry (CSG).

This crate is a facade that re-exports manifold-csg. Both crates expose the same API — use whichever name you prefer.

Migrating from 0.0.x

If you were using the original manifold3d 0.0.x (by @NickUfer, transferred to this project), the API has changed significantly. See the migration guide, which is structured for AI-assisted migration.

Notable changes:

• Newtype wrappers (PositiveF64, Point3, Vec3, Matrix4x3, ...) replaced by plain primitives (f64, [f64; 3], [f64; 12])
• manifold3d-macros crate removed — warp/set_properties callbacks are now closures
• Method names aligned with the manifold3d C API (new_cuboid → cube, convex_hull → hull, etc.)
• nalgebra_interop feature renamed to nalgebra
• No export feature (upstream removed MeshIO in v3.4.0; use a dedicated mesh I/O crate)

Quick start

use manifold3d::{Manifold, CrossSection, JoinType};

let cube = Manifold::cube(20.0, 20.0, 20.0, true);
let hole = Manifold::cylinder(30.0, 5.0, 5.0, 32, false);
let result = &cube - &hole;
