rapier VS threlte

Ok, so this uses https://rapier.rs/ which is very cool

Rapier, alongside https://nalgebra.org/ (which it uses underneath) has seriously good documentation and some advanced features like cross-platform determinism (something made hard by the way floating point differs between platforms)

Code examples: see examples2d, examples3d-f64 and examples3d directories

What are the pros and cons compared to something like Rapier? When should one use Bevy XPBD instead of Rapier, or vice versa?

Still using Rust in a browser-based multiplayer party game I'm working on! I'm using Actix Web for the backend and rapier2d to handle my game's physics. I'm looking to make some more connections amongst the developer / gaming community through my game down the line.

I have noticed that Rapier 0.17 contains a RopeJoint struct, which constrains maximum distance between two dynamic bodies. It doesn't seem to have found its way into bevy_rapier3d yet so I haven't understood whether it supports (half of) my use case, and looking at the code (https://github.com/dimforge/rapier/blob/master/src/dynamics/joint/rope_joint.rs) I really cannot see how it is actually implemented and how I could extend it to also set a minimum distance, but this may be a place to start.

I was also frustrated with the kcc, so I opened a PR that fixes most of my issues: https://github.com/dimforge/rapier/pull/446

Likewise, see the js bindings of Rapier.

Maybe check out how Rapier does it. Rapier is likely the most advanced physics engine in Rust. (Though Embark Studios is doing some crazy stuff with ML physics.)

Thanks! Threlte is "just" offering a declarative way to express Three.js. If you know how the `` component and its props and event handlers work, you can use the Three.js documentation for everything else.

Apart from that with Threlte I personally practice documentation-driven-development, so ecosystem packages are exhaustively documented. If you're missing something, let us know via an issue[1] or on Discord[2].

Accessibility is a topic we didn't care enough yet to be perfectly honest. Accessibility doesn't stop at screen readers though, it's about contrast, size, colors, motion, reachability, and so much more that we cannot provide and are a consumer topic. Naturally WebGL apps suffer from being practically invisible to screenreaders. There are workarounds[3] but essentially this has to be solved by consumers of Threlte (devs) and hopefully by browser vendors at some point in the future.

more specifically it's using the svelte wrapper of three.js called Threlte: https://threlte.xyz/

Three.js is great when there is a layer between me and it's API. Been playing with https://threlte.xyz/ and really enjoying it.

Maybe try https://threlte.xyz/

Now this is a very high level overview and a lot of really important stuff is missing. Things like event propagation, pointermissed events, different event targets, a super clean syntax and more is all implemented in Threlte 6's interactivity plugin. Check out the code here.

GPT-4 is a fantastic tool for coding, really looking forward to using it with the latest Svelte docs. Perhaps consider adding the documentation for Threlte?

) with complex functionality, since the app needed a graphics pipeline and I wanted to write one up myself. The next page I made did not need a pipeline, so I opted to use Threlte (a Svelte version of react-three-fiber) to make the code simpler to write and easier to maintain. If a scene you want to create has a lot of different meshes, materials, animations, etc. you might be best off using Blender to get it looking perfect. You can export from Blender as .gltf files which can be imported into Three. If you want a more specialized solution, I'd need to know your use case a little better. How are you building the scenes?

Hey, awesome work! Check out gltf.report for a quick and easy tool that can resize textures, prune objects and weld/simplify geometry. I’m not sure what Threlte version you’re using, but starting from Threlte 6 which is coming in the next weeks we’re recommending @threlte/gltf for the best possible gltf workflow. Check out our Discord if you need any help!
