gltfjsx VS use-cannon

Hello! I loaded a model using https://gltf.pmnd.rs and it displays correctly, but there are weird gaps that you can see through on the edges. This is a Next.js project with ts. I'm using @react-three/fiber and @rect-three/drei to use three.js in react. I'll attach the file that creates this object, but if there's anything more you need, just ask me. Here's the file that contains the code of this object:

Then we need to generate a react component that will contain the markup of this model to add it to the scene. Let's use the official resource from the @react-three/fiber developers.

especially for what you describe above. it can lay out a glb model declaratively, the whole scene is yours to control. watch the first video here https://github.com/pmndrs/gltfjsx and then use that tool:

stuff like this doesn't have to be keyframed, you can just rotate model groups. im sure this will be overwhelming atm but if you have the time watch the video there https://github.com/pmndrs/gltfjsx models in threejs are blobs, they are not meant to do anything. people traverse them and create mutations. but that tool puts the entire model scene under your control, every node in its graph is declarative now, to my it dynamic is trivial at that point.

the second practically doesn't exist in vanilla three. a gltf is a blob that you throw into the scene. pair three with react and blender will be a lot more useful: https://github.com/pmndrs/gltfjsx (watch the first video there)

I want to implement this for a gltf model loaded as a gltfx. MeshWobbleMaterial is not getting qpplied. i don't know what to where to add the component either. i have attached the code below,

Have you compressed your models with https://gltf.pmnd.rs ? ( sorry this is unrelated to your post ) or you could use https://github.com/pmndrs/gltfjsx ( same thing but you use it like an npm package )

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?

For this example we are going to use Reac Three Cannon a specific library to create physics. You can use Rapier, another cool library, but is under development right now.

"Cannon" is the rigid body physics engine who includes simple collision detection, various body shapes, contacts, friction and constraints.

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?

you use this library: [@react-three/cannon](https://github.com/pmndrs/use-cannon)

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.

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.

There’s https://github.com/pmndrs/use-cannon for R3F physics too.

physics are easy, here's a 60 loc arkanoid using use-cannon: https://codesandbox.io/s/sweet-babbage-66cd7
