mesh

A Rust workspace for 3D triangle mesh processing, providing tools for mesh repair and shell generation.

Crates

mesh-repair

Triangle mesh repair utilities:

• I/O: Load and save STL, OBJ, and 3MF formats
• Validation: Detect holes, non-manifold edges, inconsistent winding
• Repair: Fill holes, fix winding order, weld vertices, remove degenerate triangles

use mesh_repair::Mesh;

let mut mesh = Mesh::load("model.stl")?;

// Check for issues
let report = mesh.validate();
println!("{}", report);

// Repair and save
mesh.repair()?;
mesh.save("repaired.3mf")?;

mesh-shell

Generate shells around 3D meshes using SDF-based offset:

• SDF offset: Voxelize mesh, compute signed distance field, extract isosurface
• Variable offset: Per-vertex offset distances via interpolation
• Shell generation: Create inner/outer surfaces with rim closure

use mesh_shell::{apply_sdf_offset, generate_shell, SdfOffsetParams, ShellParams};
use mesh_repair::Mesh;

let mesh = Mesh::load("model.stl")?;

// Apply SDF-based offset
let params = SdfOffsetParams::default();
let result = apply_sdf_offset(&mesh, &params)?;

// Or generate a complete shell (inner + outer + rim)
let shell_params = ShellParams::default();
let shell = generate_shell(&mesh, &shell_params)?;
