Ray Tracer Challenge

A test-driven implementation of a 3D ray tracer in C++.

Building

This project uses CMake for building. You'll need:

• CMake 3.10 or higher
• A C++17 compatible compiler
• Catch2 (header-only testing framework)

Setting up Catch2

Catch2 is a header-only testing framework. You can either:

1. Download Catch2 manually:

   mkdir -p tests
   cd tests
   curl -L https://github.com/catchorg/Catch2/releases/download/v3.5.0/catch.hpp -o catch2/catch.hpp

2. Or use CMake FetchContent: The CMakeLists.txt can be updated to automatically download Catch2.

Building the project

mkdir build
cd build
cmake ..
make

Running tests

cd build
./tests
