A raytracing program built from scratch in C language, using MinilibX minimal graphics library, with pseudo-xml files as input, a dynamic render realtime viewer, and the ability to save bmp at your resolution of choice, and the ability to render on multiple devices for faster distributed rendering.
This project's main goal is learning raytracing from scratch, making a simple pseudo-xml parser expandable by design, and distributing computational tasks using C sockets to implement cluster rendering.
- Simple shapes : sphere, cone, cylinder, ...
- Complex shapes : hyperboloid, torus, hollow cube, ...
- Shading : diffuse, specular, transparency, reflection, refraction
- Mappings : diffuse, specular, normal, transparency, reflection.
- Manipulations : plane cut, object limiting, texture cutting.
- Anti aliasing : 1x 2x 4x
- Smooth shadowing
- Parallel light
- 3d red-blue stereo rendering
- Mandelbulb fractal
make -C ./libs/MinilibX ; make
Open the scene specified in the gui view
./rt scene_file.xml
Render the scene to the bmp file
./rt --no_window save_file.bmp scene_file.xml

The GUI mode gives you the freedom of moving the camera, enabling and disabling some effects and saving the result to a bmp.
