Raw

raytracer

This project is a raytracer written in C++. The goal of this project is to implement a raytracer that can render scenes with spheres, planes, lights... The raytracer supports features such as translation, rotation, and drop shadows. The raytracer outputs the rendered image to a PPM file.

development

  1. Clone the repository.
git clone git@github.com:Jabolol/raytracer.git .
  1. Create a build directory.
mkdir build && cd build
  1. Build the project.
cmake .. -GNinja -DBUILD_DOC=OFF -DBUILD_TEST=OFF
  1. Run the raytracer with a provided scene.
./raytracer --config ../scenes/cornell.cfg > cornell.ppm
