Implementation of a raytracing renderer in C++

Raytracing in C++

This is a personal project in which I incrementally build a raytracer, that I started to learn modern C++ and computer graphics. Going back at it from time to time !

Running the project

• Requirements : CMake, Make, a modern C++ compiler (tested with G++ >= 9), OpenMP library (for multithreading).
• Generate the Makefile by doing :

  $ mkdir build
  $ cd build
  $ cmake ..

• You can then compile and run the project with :

  $ make raytracer
  $ ./raytracer

If you want to change the rendered scene, you can do so in src/main.cpp.

Features supported

• Global illumination via path tracing
• Area lights
• PBR material (inspired by Disney's & Blender's Principled Material although much less complete) supporting diffuse, metal, refractive and emissive
• Multithreading (using OpenMP)
• Importance sampling (for diffuse BRDF and area light sampling)
• Firefly removal
