CSG Ray-Marching

CSG Ray-Marching is a small educational/experimental renderer for Constructive Solid Geometry (CSG) scenes using Signed Distance Fields (SDF) and ray marching.

It lets you compose primitives with boolean operations (union, intersection, subtraction), apply transforms and render images with basic lighting. This project was developed during the STAG 2025 conference hackathon, focused on CSG and ray marching.

1. Libraries, and Requirements

Libraries Used

• etu-opengl for OpenGL rendering
• json for json loading and formatting

Software Requirements

• C++: >= C++23
• CMake: >= 3.20
• Compiler: GCC/Clang/MSVC with C++23 support

2. Install & Build

1. Clone the repo

git clone https://github.com/bigmat18/csg-raymarching.git
cd csg-raymarching

2. Configure and build

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --config Release -j

3. Run the demo

./build/hackmore

3. Results

The final scene is based on a model built by Davide Fantasia, inspired by “The Creation of Adam.” The scene is interactive and leverages the techniques mentioned above.
