cgmatrix

Simple matrix library for computer graphics in Rust

About

cgmatrix is a matrix library intended to use with OpenGL and WebGL. Matrices are represented as float arrays that can be directly passed to OpenGL and WebGL.

Usage

Add cgmatrix in your Cartgo.toml file.

[dependencies]
cgmatrix = "0.1"

And, in your rust code:

fn main() {
    let camera = cgmatrix::viewing_matrix([0.0, 0.0, 200.0], [0.0, 1.0, 0.0], [0.0, 0.0, 0.0]);
    let theta = 0.5;
    let mv_matrix = cgmatrix::matmul(cgmatrix::rotate_x(theta), camera);
    println!("{:?}", mv_matrix);
}

API

Following methods are supported in cgmatrix:

Matrix creation

• zeros()
• identity()
• rotate_x(theta)
• rotate_y(theta)
• translate(x, y, z)
• scale(sx, sy, sz)
• viewing_matrix(eye, up, target)
• orthogonal_matrix(left, right, top, bottom, near, far)
• perspective_matrix(fov, aspect, near, far)

Matrix multiplication

• matmul

Vector operation

• cross(v1, v2)
• normalize(v)
