bevy_stl

A STL loader for bevy.

STL is a very simple format, which supports only triangular geometry (positions + normals), without any color / uv / texture information.

It is supported as an output format by most CAD software.

Alternatives

• by default bevy can load glTF scenes, which is a much better choice if you are looking for a way to load more complex models / scenes, including materials, animations, etc.
• bevy_obj can load Wavefront .obj files, which can carry more information than STL (such as color, material, UV coordinates)

Usage

1. Add bevy_stl to your Cargo.toml
2. Add bevy_stl::StlPlugin plugin to the bevy App
3. Load STL assets by passing paths with ".stl" extension to asset_server.load(..)

Example

fn main() {
    App::build()
        .add_plugin(bevy_stl::StlPlugin)
        .add_startup_system(setup.system())
        // ...
        .run();
}

fn setup(commands: &mut Commands, asset_server: Res<AssetServer>, mut materials: ResMut<Assets<StandardMaterial>>) {
    commands
        .spawn(PbrBundle {
            mesh: asset_server.load("disc.stl"),
            material: materials.add(Color::rgb(0.9, 0.4, 0.3).into()),
            ..Default::default()
        })
        // ...
}
