A CPU based path tracing renderer engine implemented in C++
This project aims to explore and demonstrate the fundamentals of ray tracing — generating images by tracing the path of light as rays, handling reflections, refractions, shadows, etc.
At present, this implementation supports:
- Basic ray–sphere intersection
- Basic ray-box intersection
- Phong shading model (ambient, diffuse, specular)
- Shadows (shadow rays)
- Reflection & recursive reflection
- Refraction / transparency (Snell’s law)
- Multiple light sources
- environment color
- Anti-aliasing (supersampling)
- Acceleration structures (BVH)
You can (or plan to) extend it with:
- Triangle intersections
- Mesh importing
- Moving the code to the GPU
- C++ compiler
- Vulkan SDK
- CMake
Here’s a sample of how to build and run the project:
# Clone the repository
git clone https://github.com/stefanbusoi/RayTracing.git
cd RayTracing
# (If using CMake)
mkdir build
cd build
cmake ..
make- Walnut
- Dear ImGui
- GLFW
- stb_image
- GLM
