Open-source mesh engine written in Rust programming language.

It could be useful for mesh modification, processing, fixing, etc.

https://crates.io/crates/meshmeshmesh

Run the following command:

cargo add meshmeshmesh 

• Triangle/Ray intersection
• Mesh/Ray intersection
• Face normals calculation
• Area
• Finding non-manifold edges
• Is connected
• Mesh -> Graph
• ... and more ;)

• Mesh welding
• Split by angle
• Normals flipping
• Mesh planar simplify
• Mesh deduplication

• 3D Polygon triangulation with holes

This library works natively on .bim file format, which is open minimalist text mesh format described here: https://github.com/paireks/dotbim

Example for loading dotbim scene:

use std::fs; use serde_json::from_value; use meshmeshmesh::*; fn import_scene_example() { let path = "File.bim"; let read_file = fs::read_to_string(path).unwrap(); let json: serde_json::Value = serde_json::from_str(&*read_file).unwrap(); let input_scene: scene::Scene = from_value(json).unwrap(); //... }

There are many ways to export or convert into this file format using tools described here: https://github.com/paireks/dotbim?tab=readme-ov-file#apps-supporting-bim

meshmeshmesh is using:

• iTriangle (https://github.com/iShape-Rust/iTriangle) for triangulation / tesselation.
• serde & serde_json (https://github.com/serde-rs/json) for json serialization / deserialization.

meshmeshmesh is under the AGPL-3.0 license.
