Update vertices of a sphere

[Necips]

Hello, I am trying my first steps with three.js and have encountered a first hurdle … It seems that “sphere.geometry.needsUpdate = true;” has an effect only the first time. Nothing happens with all further calls. What am I doing wrong?

My source code so far:

The goal: The vertices of the sphere should change constantly.
The gravitation()-function works as you can see:

Try verticesNeedUpdate instead, needsUpdate does not exist.

I discovered the shape of a sea shell.

Another sea shell mesh:

SeaShell Mesh from point array? extrude along path?

I have and algorithm that generates seashell geometry in Python. I’d like to rewrite it in three.js and generate many different types of shells on the web. I’ve searched this forum and Stackoverflow and am still not sure. Can Three.js create a complex mesh from a generative point array? I’ve looked at BufferGeometry and it doesn’t look like it can, but I’m not sure. My algorithm generates points from curves, (“cross sections”, “ellipses”, “ribs”) along a spline. It’s kind of like extruding a s…
