Communication

• If you have a bug or an issue, please contact us.

Installation

SSH

G++ 20+, LibConfig and SFML are required to build Raytracer.

git clone [email protected]:UwUClub/RAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAytracer.git raytracer

HTTPS

Use any tools that can clone by HTTPS, use https://github.com/UwUClub/RAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAWAytracer.git

Compilation

Using the script

./build.sh

or

bash build.sh

If you have some errors but the compilation works, please ignore them.

Usage

./raytracer <config_file>

Quick Start

./raytracer tests/test.json

Plugins

A list of plugin are implemented, those are dynamic libraries. You can theorically add your own plugins to the project. Just drop the .so in the plugins folder And implement our Api.hpp, to let our library handler load it.

Config file example

camera :
{
  resolution = { width = 1920; height = 1080; };
  position = { x = 0; y = -100; z = 20; };
  rotation = { x = 0; y = 0; z = 0; };
  fieldOfView = 72.0; # In degree
};

primitives :
{
  # List of spheres
  Sphere = (
    { x = 60; y = 5; z = 40; r = 25; color = { r = 255; g = 64; b = 64; }; } ,
    { x = -40; y = 20; z = -10; r = 35; color = { r = 64; g = 255; b = 64; }; }
  ) ;
  # List of planes
  Planes = (
    { axis = "Z" ; position = -20; color = { r = 64; g = 64; b = 255; }; }
  ) ;
};

lights :
{
  ambient = 0.4; # Multiplier of ambient light
  diffuse = 0.6; # Multiplier of diffuse light

  # List of point lights
  PointLight = (
    { x = 400; y = 100; z = 500; }
  ) ;
};

• camera : Indicate that we are creating a new camera
  • resolution : Two int representing the resolution of the camera
  • position : The position of the camera in a 3D world
  • rotation : The rotation (orientation) of the camera in a 3D world
• primitives : Indicate that we will create primitives
  • THE FIELD HERE DEPENDS OF WHAT YOU HAVE IMPLEMENTED
• lights : Indicate that we will create the lights
  • ambient : The multiplier of ambient light
  • diffuse : The multiplier of diffuse light
  • PointLight or DirectionalLight : Indicate the type of light we will create
    • x : The x pos of the camera in a 3D world
    • y : The y pos of the camera in a 3D world
    • z : The z pos of the camera in a 3D world
