The Ray Tracer Challenge - 022 - Planes

Until now our only body type is a sphere. This episode we will introduce the next one: A Plane. Finally a real floor for our renderings.
Join me, while I implement chapter by chapter from the book "The Ray Tracer Challenge" by Jamis Buck in Rust a language completely new to me.
Come with me on the journey of learning the Rust programming language, while implementing a Ray Tracer in a Test driven fashion, to have fun and (hopefully) create some astonishing rendered graphics.
Let's study the inner workings of a Ray Tracer, and take a look under the hood of the Rust language, while taking on this challenge on a weekly basis.
All the code produced within this series is provided on github, for you to
follow along.

Hi Jakob, Great video!
I was able to intersect sphere and plane. But I am having hard time to visualize (understand) the logic for a cylinder. Any tips? And thanks again for the videos.

[@MrJakob]

I haven’t yet started implementing cylinder intersection yet. Therefore I did not think about this properly yet. Once I am at that point, I hope to come up with an understandable explanation ;). Should I fail at that, please feel free to ask the corresponding question again, at that point :).

Page 130 I get a massive shadow on the wall from the light. I tried to post a link but YT removed it I think

[@MrJakob]

Yes, TH-cam will remove posted links, as it assumes it is spam.
