Module transforms 

3D transformation functions for computer graphics.

This module provides functions to create and manipulate transformation matrices commonly used in 3D graphics, including translation, rotation, scaling, and projection matrices.

Examples

use rs_math3d::transforms;
use rs_math3d::vector::Vector3;
 
// Create a translation matrix
let translation = transforms::translate(Vector3::new(10.0, 5.0, 0.0));
 
// Create a perspective projection matrix
let projection = transforms::perspective(
    45.0f32.to_radians(),  // Field of view
    16.0 / 9.0,            // Aspect ratio
    0.1,                   // Near plane
    100.0                  // Far plane
);

Functions
