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 .

2. Create a build directory.

mkdir build && cd build

3. Build the project.

cmake .. -GNinja -DBUILD_DOC=OFF -DBUILD_TEST=OFF

4. Run the raytracer with a provided scene.

./raytracer --config ../scenes/cornell.cfg > cornell.ppm
