euler

An experimental mathematics library for computer graphics.

Project ideas

• 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.

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, -1.0, 1.0);
let view = euler::Transform {
    translation: vec3!(1.0, 0.0, -1.0),
    rotation: quat!(1.0, 0.0, 0.0, PI / 2.0),
    scale: vec3!(1.0),
}.matrix();
let inverse_view = view.invert();
let world = inverse_view * vec4!(eye.xy(), -1.0, 0.0);
let ray = world.xyz().normalize();
