Overview

This README provides essential information about the Raytracer project, a school assignment for the B4 - Object-Oriented Programming course (B-OOP-400). Raytracer is a program designed to generate images by simulating the path of light as it interacts with various geometries, producing realistic digital images.

Project Features

Raytracer boasts a range of features, allowing for flexible and extensible ray tracing:

  • Primitives: Supports basic shapes like spheres and planes.
  • Transformations: Includes translation capabilities.
  • Lighting: Handles directional and ambient lighting.
  • Material: Allows for flat color rendering.
  • Scene Configuration: Easily configure scenes with primitives, lighting, and cameras.
  • Transformation: Incorporates rotation features.
  • Shadows: Supports drop shadows for realistic scenes.
  • More Primitives: Implement triangles, and .OBJ file support.
  • Advanced Transformations: Explore scaling, shearing and transformation matrices.
  • Advanced Lighting: Experiment with multiple directional and point lights, colored lighting, and the Phong reflection model.
  • Advanced Material: Add transparency, refraction, reflection, and various texturing options, including file-based, procedural chessboard, and Perlin noise texturing.
  • Scene Configuration: Go further with scene-in-scene importing, antialiasing through supersampling, adaptive supersampling, and various optimization techniques like multithreading.

Scene Configuration

Configure your scenes using an external file. The provided example demonstrates the structure of scene configuration using the libconfig++ format.

For examples of scene you can find them in the ./scenes folder.

Libraries

The project makes use of the following libraries:

  • libconfig++ (for scene configuration parsing)
  • SFML 2.5.1 (for display)
  • C++ 20

Building the Project

To build the project install the dependencies listed above, then run these commands:

cmake . && make -j

A raytracer binary will be created To run it:

./raytracer [PATH TO THE SCENE .cfg FILE]

Project Structure

Here's a brief overview of the project structure:

  • ./include: Header files
  • ./scenes: Scene configuration files
  • ./screenshots: Generated image files
  • ./shared: Shared utilities
  • ./src: Source code

Conclusion

The Raytracer project provides a fantastic opportunity to delve into the world of raytracing and computer graphics. Whether you stick to the mandatory features or push the boundaries to create a photorealistic raytracer, this project allows you to explore the captivating realm of computer graphics and rendering.
