euler

An experimental mathematics library for computer graphics.

Project ideas

• Wrapper around cgmath, solving the most common tasks quickly.
• Specifically for 3D computer graphics.
• Layout and handedness follows OpenGL conventions.
• No distinction between 'point' and 'vector' types.
• No need to import traits or modules for most functionality.
• GLSL-like constructors for vectors and matrices.
• All angles are in radians.
• All types are base f32. Only f32 and f64 bases are supported.

Demonstration

Unprojecting a ray

let projection = mat4!();
let inverse_projection = projection.invert();
let ndc = vec2!(-0.5, 0.5);
let eye = inverse_projection * vec4!(ndc, -1, 1);
let view = euler::Trs::new(vec3!(1, 0, -1), quat!(1, 0, 0; std::f32::consts::PI / 2.0), vec3!(1.0)).matrix();
let inverse_view = view.invert();
let world = inverse_view * vec4!(eye.xy(), -1, 0);
let ray = world.xyz().normalize();
