Project mention: 3D and 2D: Testing out my cross-platform graphics engine | news.ycombinator.com | 2024-04-02
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)

Project mention: Egui 0.27 – easy-to-use immediate mode GUI for Rust | news.ycombinator.com | 2024-03-27
Thanks for the feedback!
It is definitely fixable. Take a look at https://github.com/emilk/egui/issues/996 for some examples of how others have styled egui, or try out https://app.rerun.io/
Styling is done with `ctx.set_style`, but creating a nice style isn't very easy at the moment (basically you'll have to tweak constants in code, and then recompile). I'm working on making it easier as we speak though!

... I remember inventing signals circa 2005 for a knowledge graph editor I worked on in GWT back when I didn't care about knowledge graphs. Not long after that I was using similar concepts to develop a complex Silverlight decision support application for sales territories.
I'm still a little appalled that people have forgotten how to make HTML form applications like we made in 1999 and frequently use React for things that don't really need it. React has, I think, one of the most elegant methods of implementing a widget set ever invented (sure beats XAML, FXML, Visual Basic, etc.) but it doesn't support a real answer to maintaining application state that would be adequate for applications as complex as RIAs made by early adopters in 2005.
My favorite use for React is
which works like a cross between VRML and Unity Framework. Here you can easily build a virtual world that people can experience with desktop, mobile and VR headsets. Something you can't do with HTML forms!
I have a few side projects based on HTMX but I am pretty sure we will see something like it but better soon. In particular back end frameworks need to be updated for the new reality. Often you have a "component" like a dropdown box which can either be drawn as part of a bigger page or updated on its own and you really need some way you can reuse the HTML template for those purposes and hopefully also reuse associated code that does database lookups and such.

Project mention: Show HN: Driftmania – an open source PICO-8 racing game | news.ycombinator.com | 2024-02-16
Nice work, gives me very Micro Machines vibes for the NES. The only thing I don't like about PICO-8 is that its completely closed source. An open source alternative that seems very promising is Pyxel. It has similar retro / pixel art limitations, a built-in sprite editor, music tracker, etc.

Bullet
Bullet Physics SDK: real-time collision detection and multi-physics simulation for VR, games, visual effects, robotics, machine learning etc.
For typical game physics engines... not that much. Math libraries like Eigen or Blaze use lots of template metaprogramming techniques under the hood that can help when you're doing large batched matrix multiplications (since it can remove temporary allocations at compile-time and can also fuse operations efficiently, as well as applying various SIMD optimizations), but it doesn't really help when you need lots of small operations (with mat3 / mat4 / vec3 / quat / etc.). Typical game physics engines tend to use iterative algorithms for their solvers (Gauss-Seidel, PBD, etc...) instead of batched "matrix"-oriented ones, so you'll get less benefits out of Eigen / Blaze compared to what you typically see in deep learning / scientific computing workloads.
The codebases I've seen in many game physics engines seem to all roll their own math libraries for these stuff, or even just use SIMD (SSE / AVX) intrinsics directly. Examples: PhysX (https://github.com/NVIDIA-Omniverse/PhysX), Box2D (https://github.com/erincatto/box2d), Bullet (https://github.com/bulletphysics/bullet3)...

To highlight this shift, we are introducing a new website which is now fully automated with Github. The paint is still fresh, but we hope to expand it with more information about the MonoGame Foundation, like how it operates, and how to join it or contribute.

assimp
The official Open-Asset-Importer-Library Repository. Loads 40+ 3D-file-formats into one unified and clean data structure.
Project mention: The Asset-Importer-Lib Minor Release Version 5.3.0 is out | /r/GraphicsProgramming | 2023-09-26 -
I love Go, yet I've never thought of it as a language with usable game engines. I'm extremely happy to find I was very wrong about that!
I'm woefully behind the curve on compiling to WASM, though, and I've yet to experiment much with tinygo so I have no idea how far I would get in creating a game people could enjoy in a browser without having to download a big bundle of assets. It's reassuring to see WASM mentioned explicitly as a compilation target [1] by Ebitengine though.
