Just came across this really cool video from Tsoding, where he explains how computers produce 3D graphics.
TLDR, the main takeaway is as simple as this formula:
(x, y, z)
x' = x/z
y' = y/z
But he also dives into concepts like the rotation matrix, drawing vertices and edges, and how you can create a super simple 3D engine using HTML context and display a penger model. The source code is also out for anyone who wants to play with it.
I've always wondered how computers process 3D, and why different 3D softwares have a differently oriented axis, and this answers a lot of those questions for me. Would highly recommend anyone working with 3D with a nerdy itch for algorithms to check out this video!

I had a random idea: what if I built a 3D Taekwondo game that runs entirely in the browser? 🥋
Well… I actually went and built it 😂
Introducing DOJANG — a little side project that started as an excuse to explore 3D development and turned into a surprisingly fun game.
You can:
- Spar against AI opponents at different difficulty levels.
- Practice Taekwondo techniques and combinations.
- Compete using arcade or Taekwondo-inspired scoring rules.
- Work your way through belt progression.
- Play on desktop or mobile.
It's built with React, Three.js, TypeScript, and a lot of experimentation with animation, physics-like combat interactions, and game mechanics.
This was a fun opportunity to step outside my usual product and interface development work and explore a completely different kind of interaction design.
There's still plenty I'd love to improve, but that's part of the fun of building things.
Anyway, enough talking. Go throw some kicks 😂

Would love to hear what you think (and whether you can beat the black belt 👀).
sharp minds build great projects
Complete Book Design - Start Your Business
I have designed a complete business guide from zero to success. I have done the cover design with the title 'Start Your Business' using the 'gold' color and designed it to inspire. The book also provides a step-by-step business plan from a beginner's guide to a completely successful business. I also used proper images that are relevant to the topic. I provided illustrations, charts, and diagrams to help with understanding. I have designed this book to give entrepreneurs a smooth experience.
wow very nice work
