Why react-three-rapier does not use worker like use-cannon
I'm using rapier physics lib in my own project, and i did that using workers too, i refered this repository https://github.com/pmndrs/use-cannon and when i saw the similar project to use physics lib into react-three-fiber but with rapier https://github.com/pmndrs/react-three-rapier, i notice that they don't use workers... There is some reason to not use workers with rapier? Weren't we supposed to use physics on workers for performance reasons?

How to prevent camera from entering cubes
I'm trying to build a maze using react-three/fiber and react-three/cannon. I've added first person controls using this Minecraft Sandbox and a layout very similar to the example on the react-three/cannon Github page, just with more boxes acting as walls. But, instead of stopping at the boxes/walls, the camera moves directly in and through the larger ones and tumbles over the smaller ones. Any idea how to prevent this?

Challenges of a web VR throwing game
Since I'm a big Poimandres fan I looked into react-xr, and it was very easy to get a first WebXR project up and running. Unfortunately, there are many dependencies in the ecosystem which slowed me down: react-xr is built on top of react-three-fiber which is built on top of Three.js, and physics is enabled by use-cannon which is built on top of cannon-es. For a long time I was running into issues and helping fix them with a couple of pull requests, and ultimately it was preventing me from working on the actual project. Still, Poimandres is a great community and I got a lot of inspiration from the content being shared in the discord.

[AskJS] Why don't they make JavaScript multi-threaded?
I'd be really curious to hear how you'd refactor a library like use-cannon? The primary challenge with it's development is exactly the issue that the other commenter described: building the API bridge between the WW and the main thread. I have been thinking about this for at least a full year and I haven't come up with a better way to structure the code - yet this seems like an ideal use case for a webworker.

Implementing Bloom Effect with Mapbox and Three.js
Regarding the optimization of the effect, I found an issue on the three.js GitHub repository: https://github.com/mrdoob/three.js/issues/14104 The alpha channel issue seems to be a difficult problem, which has been present since 2018. At the end of the discussion, a solution proposed by a contributor is not to modify the UnrealBloomPass but to blend the source texture and target texture in the shader.

React: A Mess That Shouldn't Exist In Web Development
Most of frontend libraries are made with Vanilla JS. An example of library that you might frequently use is "Chart.js". But React is not compatible with Chart.js so here it comes "React-chartjs-2" A wrapper library to work with Chart.js in React ecosystem. Oh you want to use "three.js" for some cool 3D? you will need "React-three/fiber". In my case, I need to implement "telegram-web-app", not so fast, I have to create my own wrapper to be able to use it.
