raytracing

following the ray tracer construction kit

features

raytracing implementation from scratch. this means no dependencies (aside from std)! yes, there's a handwritten implementation of everything

• image output as .ppm in ./artifacts
• all the vector and matrix math derived by hand
  • ray intersection with spheres
  • ray intersection with infinite planes
  • (todo) ray intersection with meshes from .obj files
• light calculation with the phong reflection model
• optimization
  • (todo) multithreading for faster computation
  • (todo)
• my own handwritten "ababa" config language
  • tokenizing
  • AST
  • proc macro for structs (ok this is the only place i used dependencies LOL although tbf i could implement it by hand)
