Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Using simplex noises and a circular mask for map generation
This is the simplex lib I use in JS https://github.com/jwagner/simplex-noise.js

do games like minecraft start wrapping their "infinite" world at some point?
I was curious about whether simplex noise would repeat so I looked at the library I use, jwagner's simplex-noise.js. And it does. But … simplex noise wraps at a boundary that does not line up with your pixel/block grid. So it won't match exactly. Here's a test program:

Show HN: Checkers Twist – The game Checkers/Draughts/Dames on an irregular grid
- some corners will connect less than 4 tiles. This does the opposite of the previous point, as this removes diagonals. This limits your moves in a specific direction, but can also protect you from your opponents. It's the kind of features that can be used both as a defense and as attack.
And the boards are procedurally generated, so you can play unique games each time (or you can re-use the same boards if you like). It is done with my engine Polygonjs ( https://polygonjs.com/ ), and if you're curious about how the grid is built, here is an example scene you can play with: https://polygonjs.com/gui/irregular_quad_relaxation/edit .
The game is not free on Steam/iOS, but the demo has no time limit, it just gives you a handful of boards to play with.
I hope that's fun!

On the importance to make games during the game engine's development
That's the path I took with Polygonjs ( https://polygonjs.com ), and a game I've just released ( https://polyreplay.com/minesweepertwist ), with more coming shortly.
But it didn't start like that. It only started as a tool I could use to deliver client projects, as I was trying to become a freelance for interactive 3D scenes for the web.
Project after project ( some examples here: https://polygon-lab.com/ ), I could improve Polygonjs. Then I found clients who would be interested enough to buy licenses, and would give valuable feedback which would help the project grow even more.
And a few clients asking for not just interactive sites, but also games. This pushed Polygonjs further, and after several games released, it definitely qualifies as a game engine.
So this is generally an advice I give to people who want to become freelancers. Build a tool that solves a problem in your space, as this gives you an edge, and you'll also get the chance to confront that tool to reality, which will help it - and you - grow. This becomes a virtuous circle very quickly.

how can I convert a 3D model into an SDF, a signed distance field
You can have a look how I do it in Polygonjs (which is a node-based design tool based on threejs), in this example scene.

ThreeJS capabilities
If you're familiar with Houdini, I invite you to try Polygonjs, which is based on threejs and inspired by Houdini. You can basically build threejs in a procedural way, with just nodes.

I’m starting to get into generative media and visual making and I want to know what software to use other than touchdesigner.
You could try Polygonjs. It's inspired by Houdini, so has a lot in common with TouchDesigner (it's fully node-based, you can create audio reactive apps), and it works on the web, which makes scenes very easy to share.

Help me out ya’ll. Spline 3D vs Dora 3D?
Can I invite you to try Polygonjs as well?

Sdf – Generate 3D meshes based on SDFs
you can generate an SDF from a mesh with [Polygonjs](https://polygonjs.com). Here is an [example scene](https://polygonjs.com/examples/bynode:mat:raymarchingbuilder...).
It won't generate a function, though. Instead it creates a 3D texture which is used inside the raymarching material. In my experience this is much more performant, and also art-directable.
(disclaimer, I'm building Polygonjs)

Need help for job
It sounds like you need a dynamic system that runs in the browser. Maybe try Polygonjs ( https://polygonjs.com )? The the 3rd interactive scene on the front page gives an idea of a dynamic model. I run it, if that of interest, happy to give more examples

Vegetation modelling tool
If you ever wanted to do a vegetation modelling tool for the web, I invite you to try it on Polygonjs, it has a lot of similarities with Houdini (node-based, procedural modeling, HDA system, etc) and is all web/realtime. And open source.
