nvec3

A simple, header-only C++23 library for 3D vector mathematics.

input.mp4

Features

• Intuitive vector arithmetic (+, -, *, /).
• Functions for dot product, cross product, magnitude, norm, lerp etc.

Usage

To use nvec3 in your project, simply include the src/vec3.hpp header file.

#include <print>
#include "vec3.hpp"

int main() {
    nvec3::Vec3 v1(1.0f, 2.0f, 3.0f);
    nvec3::Vec3 v2(4.0f, 5.0f, 6.0f);

    // Add two vectors
    nvec3::Vec3 sum = v1 + v2;
    std::println("Sum: {}", sum);

    // Calculate dot product
    float dot_product = nvec3::dot(v1, v2);
    std::println("Dot product: {}" , dot_product);

    // Calculate magnitude
    std::println("Magnitude: {}", v1.length());

    return 0;
}

Build

To build the demo programs located in the demo/ directory.

1. Build the sphere demo:

   mkdir build
   make sphere

   The executable will be placed in the build/ directory.

2. After you're done, you can clean the build directory:

   make clean
