I amazed of someone’s work: Ray Tracing In Console  
You can check his/her work on [youtube](https://youtu.be/QkETiyYWh2o)

The code is made in C++ so i try to port it into under processing environment and made some modifications.

Nb: Dont ask me how it works, simply, i dont know. Just sharing other person work tho.

Cool by the way you can use built in processing `constrain` function instead of clamp. Also did you know about Thomas Diewalds [pixelflow](https://github.com/diwi/PixelFlow) library, which has some stunning examples albeit using GLSL.

I knew, just forgot to adapt that part with the processing since previous code works with double and constrain works with float.

Pixelflow? hmm seem interesting to give it a try!

Previously people use Sunflow library for static raytracing [here’s](https://twitter.com/monkstoneT/status/1007966712447295488) something I created earlier with PiCrate (ruby-processing on for raspberrypi)

I wrote a Raytracer with Processing, too. Twice. Just to teach it better: [https://youtu.be/9NJ7sW\_3qt8](https://youtu.be/9NJ7sW_3qt8)
