The Fundamentals Of Rotational Dynamics In 3D Rigid Body Simulation

In this article, I hopefully clear the most important parts in rotational dynamics related to 3D rigid body simulation and introduce them in an intuitive way, this is mainly for non-physicists (I'm not even a physicist myself, so that's that...), so if you're a physicist or already familiar with moments of inertia well, then I don't think you're going to get anything new out of this, otherwise then this is probably for you!

It's mainly focused on engineers and programmers, so there's not a whole lot of walls of math text and giggles, mostly focused on the very fundamentals and applications of them

The article is also mainly to make sure I have gotten certain concepts right for the most part, so there may be some mistakes here and there, be warned

The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

CUSTOM GAME ENGINES: A Small Study

WARNING: Article moved to separate repo to allow users contributions: https://github.com/raysan5/custom_game_engines

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like [Unreal](https:

	// This should serve as an reference implementation for common collision queries for games.
	// The goal is good numerical robustness, handling edge cases and optimized math equations.
	// The code isn't necessarily very optimized.
	//
	// There are a few cases you don't want to use the procedures below directly, but instead manually inline the math and adapt it to your needs.
	// In my experience this method is clearer when writing complex level queries where I need to handle edge cases differently etc.
