# Raytracing in 256 lines of bare C++
This repository is a support code for my computer graphics lectures. It is not meant to be the ultimate rendering code or even physically realistic. It is meant to be **simple**. This is a work in progress, I'll populate the project's wiki shortly.
This project is distributed under the [DO WHAT THE FUCK YOU WANT TO PUBLIC LICENSE](https://en.wikipedia.org/wiki/WTFPL) lincense.
If you are looking for a software rasterizer, check my other part of the lectures:
https://github.com/ssloy/tinyrenderer/wiki
In my lectures I tend to avoid third party libraries as long as it is reasonable, because it forces to understand what is happening under the hood. So, the raytracing 256 lines of plain C++ give us this result:

# Homework assignment
[homework_assignment branch](https://github.com/ssloy/tinyraytracer/tree/homework_assignment) contains all necessary stuff to easily add environment maps:

... and triangulated meshes:

All boring code (image/obj files serializer etc) is already added; to obtain the above image ot suffices to add 10-20 lines of code.
