Vector2

• A lightweight, header-only C++ class for handling 2D vectors. This class provides the basic functions to understand how the Vector2 class works with basic functions like distance and distance squared to dot product and similar

Quick Test

#include <iostream>
#include "vector2.hpp"

using vec2 = geom::Vector2;

inline void test_length()
{
    vec2 test_vec(3.0f, 4.0f);
    println("Test Length");
    print
    (
      "x: {:2.2f}\n" 
      "y: {:2.2f}\n"
      test_vec.x, test_vec.y
    );
    println("Length: {}", test_vec.length());
    println("Length Squared: {}", test_vec.length_squared());
}

int main()
{
    test_length();
    return 0;
}

compile and run

g++ -Wall -Wextra -Wpedantic -std=c++23 test_vector2.cpp -o run && ./run

Vector3

• A lightweight, header-only C++ class for handling 3D vectors. This class provides the basic functions to understand how the Vector3 class works with basic functions like distance and distance squared to dot product and similar

Quick Test

#include <print>
#include <format>
#include "vector3.hpp"

inline void test_length()
{
    vec3 test_vec(3.0f, 4.0f, 1.0f);
    println("Test Length");
    print
    (
      "x: {:2.2f}\n" 
      "y: {:2.2f}\n"
      "z: {:2.2f}\n", 
      test_vec.x, test_vec.y, test_vec.z
    );
    println("Length: {}", test_vec.length());
    println("Length Squared: {}", test_vec.length_squared());
}

int main()
{
    test_length();
    return 0;
}

compile and run

g++ -Wall -Wextra -Wpedantic -std=c++23 test_vector3.cpp -o run && ./run
