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 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:
compilation
git clone https://github.com/ssloy/tinyraytracer.git
cd tinyraytracer
mkdir build
cd build
cmake ..
make
Homework assignment
homework_assignment branch 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.
