- Reflecting surfaces make everything more lifelike. Due to our previous work they aren't that hard to implement. Let's do it!
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.

Hey Jakob, keep them coming, your channel is gold !!
Thank you very much. I am sorry for not having released a new video in such a long time. There will be more in the future, that I can assure you. In the last two month I nearly didn’t have any spare time to work on this project. But I am seeing the light at the end of the tunnel. Therefore I hope there will be a new session out soon, covering refraction and there stuff like glass 😁
@@MrJakob Didn't wanted to pressure you! I know how hard it is to find time these days. I discovered the series last week and have watched most of it and really liked the approach/commentary and of course the project. I just wanted to show interest to motivate you! Take your time
Did rust speed up the render speed or is that just your Processor's FPU ?
The implementation is purely cpu bound, as none of the computation is done on the gpu. It would be possible of course to use the gpu to enormously speed up the calculation. The main speed bump for the implementation was to utilize all processor cores using the rayon library. There is a session about when I discovered that as well.
Will it be a raytracer or a pathtracer?
