The RayTracer is a 3D rendering engine that simulates the physical behavior of light to create photorealistic images. This project implements the ray tracing algorithm to generate renders of 3D scenes with complex visual effects.

• High-fidelity Rendering

  • Physically accurate calculation of shadows, reflections, and refractions
  • Anti-aliasing for sharper images
  • Support for different output formats

• Geometric Primitives

  • Spheres, planes, cones, cylinders, and triangles
  • Precise positioning and rotation of objects
  • Extensible system for adding new shapes

• Advanced Lighting System

  • Ambient light for global illumination
  • Directional lights simulating the sun
  • Point lights for localized sources
  • Soft and hard shadows

• Customizable Materials

  • Color and texture properties
  • Ambient, diffuse, and specular coefficients
  • Configurable reflection and transparency

• Modular Architecture

  • Plugin system to extend functionality
  • Clear and documented programming interface
  • Easy addition of new materials and primitives

macOS

brew install imagemagick

Linux

sudo apt update
sudo apt install -y build-essential libsfml-dev libconfig++-dev imagemagick

make

./raytracer scenes/demo.cfg

python3.10 create_animation.py [--shpere] [--cone] [--cylinder]

The RayTracer uses .cfg files to define scenes to render. Here is a simplified example:

camera : {
    resolution = { width = 0; height = 0; };
    position   = { x = 0; y = 0; z = 0; };
    rotation   = { x = 0; y = 0; z = 0; };
    fieldOfView = 90.0;
};

primitives : {
    spheres = ();
    cylinders = ();
    cones = ();
    triangles = ();
    planes = ();
};

lights : {
    ambient = 0.0;
    diffuse = 0.0;
    point = ();
    directional = ();
};

The project includes several predefined scenes that you can use to test the RayTracer:

• scenes/easy.cfg: Simple scene for beginners
• scenes/test.cfg: Test scene with multiple primitives
• scenes/demo.cfg: Demonstration of the engine's capabilities
• scenes/artistic.cfg: Artistic composition
• scenes/space.cfg: Space scene

The project also includes a web interface for testing the RayTracer online:

cd web
python app.py
