I want make a Object3D dynamically clipping another Object3D, not basic planes clipping. by the way, what is the proper way to remove a mesh(Object3D) from scene. The Docs hasn’t mentioned it, I think it’s essential for beginners. is this OK? scene.remove(mesh);

Hi! Are you looking for operations with geometries? Like “union”, “subtract”, “intersect”. If so, take a look at this forum topic Looking for Updated plug-in for CSG

Thank you. The running demo link is dead, so I don’t know if it’s what I want or not. I want the Object3D to be dynamically clipped, not permanently, like a animation effect. https://threejs.org/examples/?q=clip#webgl_clipping_advanced

Could you put more details to explanation of what you want to achieve? Explanatory pics and an editable live code example would be great.

something like this: [clipping]

Thank you very much, that’s what I want. But I know nothing about shaders, Threejs alone can’t do that?

no. Three.js can not do that by itself. You would need to write additional code or find a third-party project that implements those features on top of Three.js. I would suggest you re-think your approach, consider what your goal is, and look for alternative ways to achieve it, perhaps Constructive …

Thanks, I am reading The Book of Shaders

It’s not an easy topic to get into, but it’s a lot of fun. If I write a book about shaders, I’ll probably call it “Fifty Shaders”

@Usnul “Fifty shaders of grain” :smiley: :+1:

Specifically about spheres, take a look at this topic: In the Orb (Shaders)
