Welcome to the community!
Great that you could adopt the tutorial in Odin! I just had a quick look at your repo and I have one suggestion for you: Odin has build in support for Array Programming so you do not need most of the helpers in your math package:
There is also a very good tutorial-series on building a software render completely in odin here: https://www.marianpekar.com
I hope you stick with Odin and enjoy the language as much as we do And do not hesitate to ask any questions.
