vec3-rs

https://crates.io/crates/vec3-rs

This crate provides a simple and efficient implementation of 3D vectors in Rust, with various utility functions for vector manipulation and operations.

Features

• Represents 3D vectors in Cartesian space.
• Includes predefined constant vectors for X, Y, and Z axes.
• Supports basic vector operations such as addition, subtraction, dot product, cross product, etc.
• Supports all primitive number types.
• Provides methods for vector normalization, linear interpolation, and angle calculations.
• Allows fuzzy equality comparison within a specified epsilon.

Example

```rust use vec3_rs::Vector3;

fn main() { let mut v1: Vector3 = Vector3::new(1.0, 2.0, 3.0); let mut v2: Vector3 = Vector3::new(3.0, 1.0, 2.0);

// Basic operations
let sum = v1 + v2;
let difference = v1 - v2;
let dot_product = v1.dot(&v2);
let cross_product = v1.cross(&v2);

// Other methods
let lerp_result = v1.lerp(&v2, 0.5);
let angle = v1.angle(&v2);
let fuzzy_equal = v1.fuzzy_equal(&v2, 0.001);

println!("Sum: {sum}");
println!("Difference: {difference}");
println!("Dot product: {dot_product}");
println!("Cross product: {cross_product}");
println!("Lerp 50%: {lerp_result}");
println!("Angle: {angle}");
print!("Are they close enough?: {fuzzy_equal}");

v1.normalize();
v2.normalize();

println!("v1 normalized: {v1}");
println!("v2 normalized: {v2}");

} ```
