Alum: A Halfedge based Polygon Mesh Library

This library is inspired by OpenMesh, hence has an API very similar to that of OpenMesh. I love using OpenMesh in C++, and wrote this library because I couldn't find an equivalent in Rust. Huge thanks to OpenMesh and it's maintainers for the inspiration!

For now, the features of this library exist to serve my other projects. It has near parity with the OpenMesh/Core module, and new features will be added as required by my other projects.

Installation

This can be added to a Rust project as a dependency from crates.io with:

cargo add alum

Or by adding the following to your Cargo.toml:

[dependencies]
alum = "0.5.5"

Usage and Features

This library uses glam out of the box for geometric types such as points, normals etc. These are enabled by the use_glam feature and can be disabled if you don't want to use glam.

You can use this library with your own geometric types for points and normals etc. by implementing an adaptor that tells this library how to work with your geometric types. Read the documentation to learn more about this. These examples demonstrate writing custom adaptors and rendering and using various features of this crate together with three_d

This library also comes with a property system just like the one in OpenMesh, with some small improvements and differences. The properties are always synchronized with the mesh elements, through additions, deletions and garbage collections which result in reordering of elements. Unlike properties in OpenMesh, the properties here use interior mutability with RefCell<T> and enforce runtime borrow checking rules. Read the documentation to learn more.
