Prefabricated shapes for the Glium OpenGL library.

The following shapes are currently provided by the library:

• Axes
• Cuboid
• Quad
• Sphere

Documentation can be found here: http://jbrd.github.io/glium_shapes

• Import the glium_shapes crate:

  extern crate glium_shapes;

• Build a 2x3x4 Cuboid with its centre-of-mass at the origin and draw it:

  let cuboid = glium_shapes::cuboid::CuboidBuilder()
               .scale(2.0, 3.0, 4.0)
               .build(display)
               .expect("Failed to build cuboid shape");
  frame.draw(&cuboid, &cuboid, your_shader_program, your_uniforms, your_draw_params);

• Examples for all shapes are provided. Just run:

  cargo run --example axes
  cargo run --example cuboid
  cargo run --example quad
  cargo run --example sphere

• Each shape is constructed using a builder object, which provides methods for customising your new shape

• By default, the geometry is constructed to suit the standard OpenGL context defaults:

  • Right-handed coordinate system (x = right, y = up, z = out of screen)
  • Front-faces taken to be counter-clock-wise

• By default, each shape is constructed with its centre-of-mass at the origin

Maintained but not actively developed. Will keep up-to-date with latest versions of rust and glium. Will add extra shapes when needed, and will happily accept contributions for extra shapes as well. Bugs will be fixed (please raise an issue if you find any!).

Contributions are most welcome! To reduce the feedback loop, please ensure you perform the following checks before contributing a patch:

• Ensure the project builds in debug: cargo build
• Ensure the project builds in release: cargo build --release
• Ensure the tests pass: cargo test
• Ensure the coding style is consistent (cargo fmt should yield no changes)
• Ensure cargo clippy --all-targets returns no warnings or errors
• Ensure cargo doc succeeds
• Ensure all the examples build and run successfully
• Ensure your name is added to the contributors list in README.md
