Working on extending the [Zdog](https://zzz.dog) library, adding some new types and tooling, patching bugs I run into on the way. All the quirks inherit from it being based on (and rendering to) SVG. SVG is Y-down, Zdog only adds Z-forward. SVG only has layering, so Zdog only z-sorts shapes as wholes. Perspective distortion needs more than dead-simple affine transforms to properly render beziers, so Zdog doesn't... - Source: Hacker News / 18 days ago

Some time ago I found zdog - it's a lightweight 3D javascript engine, for canvas or SVG. If you check out its site, you'll see it described as pseudo 3D. What does that mean? Basically zdog holds a model of 3D shapes, but renders everything as 2D flat shapes. - Source: dev.to / about 2 years ago

For some reason could not paste more links into my last comment so here are some other thoughts on things to do too. Zdog: Https://zzz.dog/ This one is a way to do vector pseudo 3d illustrations on the web, but it mostly just has a simple rotation not much beyond that. Source: over 2 years ago

Hi, I am trying to make a 3D editor for the Zdog library. Source: almost 3 years ago

For this project, I'm tinkering with ZDog (https://zzz.dog/) a nifty little flat-shaded pseudo-3d engine for the browser, written in Javascript. It's pretty simple as 3d engines go, but as one might expect, it's heavily structured around OOP and mutable objects, and makes extensive use of Javascript prototypal inheritance.

The Immutable.js README has a much more complete description of immutability and why you might want to use the library. Also worth mentioning that Immer is an alternative which is a bit easier to get started with. - Source: dev.to / over 2 years ago

You could create explicitly immutable references and state by using a tool like Immer.js or Immutable.js and do something like your example using their API. Source: almost 3 years ago

There are also libraries such as Immer and Immutable that were created to make our lives easier while dealing with immutability in JavaScript. - Source: dev.to / over 3 years ago

Use persistent immutable data structures (as implemented in, for instance, mori or Immutable.js) to represent the state. As much as possible, push calculations into referentially transparent functions (i.e., input depends purely on output) which take persistent data. Write the interactions with the real world in imperative style. Source: over 3 years ago
