3D and 2D: Testing out my cross-platform graphics engine
I am glad people are working on it!!
Have you seen Kha by any chance? It has similar goals. I find it quite awesome, but it won't gain mass adoption for a bunch of reasons. https://github.com/Kode/Kha
Someone built an immediate mode renderer on top https://github.com/armory3d/zui, which is utilised by ArmorPaint https://armorpaint.org. I also use Zui for my own bespoke 2D game engine.
I find this tech and tooling really quite amazing (just look at how little source code Zui has) given just how small the ecosystem around it is. I think Kha really illustrates what can be achievable if the lower levels have robust but simple APIs, just exposing the bare minimum as a standard for others to build upon.
For the kind of project I work on (mostly 2d games), I think it would really awesome if your framework also supported low level audio, and a variety of inputs such as keyboard, mice, and gamepads. If it also had decent text rendering support it would basically be my dream library/framework.

Single Javascript calculation VS. doing calculation in shader?
So doing the calculation on CPU and including it with other uniforms is the best way to minimise overhead. Have a look at buffers rather than individually binding each variable. See https://github.com/Kode/Kha/issues/1365 for why UBOs are not available in WebGL 2.0.

Why Kha is discontinued? Seems like an active project on github.
Kha on haxelib was discontinued many years ago - we sadly now felt it was necessary to remove it entirely from haxelib because people kept using it despite the scary warning message it prints on every run. This "lib" now contains only this readme, please see https://github.com/Kode/Kha/wiki/Getting-Started for instructions on how to actually use Kha.

Heaps: A free, open-source and cross-platform game engine
I ported my https://rpgplayground.com from AS3 to Haxe. It was the most sane technology to replace Flash, because it came with some platform independent benefits (as opposed to coding straight in JavaScript)
Not using Heaps but https://github.com/Kode/Kha.
And I think you are indeed correct in your assumption, since I know plenty of others who made that switch.

Destroy my project. Why you would not use Notan? I'm looking for constructive criticism.
I'm looking to some other libs that inspired notan, like http://kha.tech " Ultra-portable, high performance, open source multimedia framework. " Or SFML " SFML provides a simple interface to the various components of your PC, to ease the development of games and multimedia applications. "

Flash Sucks –- But everything else sucks more (2011)
At its core the beauty of Flash was the extremely tight interplay between vector graphics in nested timelines, and the the programming environment. Many people compare Flash to Unity, but I really don't find the two all that comparable. You don't create your assets in Unity, and by the time those assets get into Unity you have lost most potential for dynamic behaviour. Flash's tight integration allowed for extremely fast iterations, and its hierarchal model was very flexible and allowed you to work very fast and creatively.
I'm surprised no one has had a good crack at re-creating the core functionality of Flash circa 2004, based on web tech, or something like Kha[1]. I've thought many times about starting such a project. I think the biggest challenges are developing a solid vector rendering runtime alongside the vector drawing tools, but just about everything else that ex-Flashers want can be reduced down to some pretty simple functionality. You could even forego all the cruft of the display list, the event model, etc, and just go with a simpler immediate mode renderer and I think you'd still be retaining those core components that made Flash special.
There are so many use cases (eLearning experience, Digital Signage, Touch Screen Kiosks) that Unity isn't particularly suitable for, and for which HTML/Javascript is just clunky, that such a tool could far better accomodate.

Voronoi, Manhattan, random
Bevy. A very young engine where you need to write the game entirely in Rust—that was appealing. But fatal flaws overshadowed everything: no editor, the engine brutally enforces the ECS approach, and the game's architecture must literally bend to fit this paradigm. So, you won't migrate to another engine at all—you just throw away all the code and start from scratch.

Web Game Engines and Libraries
Missing one of the best choices as long as "maturity" isn't on the top of your list: Bevy - https://bevyengine.org/
Game engine written in Rust, leveraging ECS in almost every place and way, with a really capable WASM export option. Wrestling ECS for the first time might take you some time, but in my experience helps you keep game code as clean and decoupled as game code could be.

3D and 2D: Testing out my cross-platform graphics engine
I don't see WASM/WebGPU changing anything when it comes to gaming, as an industry, personally. 3d visualizations and interactive websites? Yeah definitely a nice improvement over WebGL 2, if years late.
WebGPU is pretty far behind what AAA games are using even as of 6 years ago. There's extra overhead and security in the WebGPU spec that AAA games do not want. Browsers do not lend themselves to downloading 300gb of assets.
Additionally, indie devs aren't using Steam for the technical capabilities. It's purely about marketshare. Video games are a highly saturated market. The users are all on Steam, getting their recommendations from Steam, and buying games in Steam sales. Hence all the indie developers publish to Steam. I don't see a web browser being appealing as a platform, because there's no way for developers to advertise to users.
That's also only indie games. AAA games use their own launchers, because they don't _need_ the discoverability from being on Steam. So they don't, and avoid the fees. If anything users _want_ the Steam monopoly, because they like the platform, and hate the walled garden launchers from AAA companies.
(I work on high end rendering features for the Bevy game engine https://bevyengine.org, and have extensive experience with WebGPU)

What Are Const Generics and How Are They Used in Rust?

WebAssembly Playground
That's possible. I did spend quite a bit of time tinkering with compiler flags, and followed the recommendations.
Some notes I found just now seems to agree with my results, though: https://github.com/bevyengine/bevy/issues/3978#issuecomment-...

Immediate Mode GUI Programming
I cannot recommend immediate mode GUI programming based on the limitations I've experienced working with egui.
egui does not support putting two widgets in the center of the screen: https://github.com/emilk/egui/issues/3211
It's really easy to get started with immediate mode, it's really easy to bust out some UI, but the second you start trying to involve dynamically resized context and responsive layouts -- abandon all hope. The fact it has to calculate everything in a single pass makes these things hard/impossible.
... that said, I'm still using it for https://ant.care/ (https://github.com/MeoMix/symbiants) because it's the best thing I've found. I'm crossing my fingers that Bevy's UI story (or Kayak https://github.com/StarArawn/kayak_ui) become significantly more fleshed out sooner rather than later. Bevy 0.13 should have lots more in this area though (https://github.com/bevyengine/bevy/discussions/9538)

ECS, Finally
I've also been enjoying building My First Game™ in Bevy using ECS. The community around Bevy really shines, but Flecs (https://github.com/SanderMertens/flecs) is arguably a more mature, open-source ECS implementation. You don't get to write in Rust, though, which makes it less cool in my book :)
I'm not very proud of the code I've written because I've found writing a game to be much more confusing than building websites + backends, but, as the author notes, it certainly feels more elegant than OOP or globals given the context.
I'm building for WASM and Bevy's parallelism isn't supported in that context (yet? https://github.com/bevyengine/bevy/issues/4078), so the performance wins are just so-so. Sharing a thread with UI rendering suuucks.
If anyone wants to browse some code or ask questions, feel free! https://github.com/MeoMix/symbiants

Intel CEO: 'The entire industry is motivated to eliminate the CUDA market'
These days, some game engines have done pretty well at making compute shaders easy to use (such as Bevy [1] -- disclaimer, I contribute to that engine). But telling the scientific/financial/etc. community that they need to run their code inside a game engine to get a decent experience is a hard sell. It's not a great situation compared to how easy it is on NVIDIA's stack.
