Continuing to think about the idea of parametric modeling and developing the previous idea: Parametric modeling from primitives (cube, sphere...) and animation I decided to do it through a function. Where the vertex ID will be passed at the input. And at the output it should return the vertices, …

I’m not native English speaker and I cannot understand what you try to do. It might be good to add an illustration of what you are trying to achieve, with arrows between input vertices and output vertices. Maybe if you build a DCEL over your mesh, you could easily traverse the net topologically (e.…

[изображение] We build a cube model. The function returns a sequence of pointers to the next vertex. We build triangles on them. 0 1 2 1 2 6 2 6 7 6 7 9 0 2 3 2 3 7 3 7 8 7 8 9 0 3 4 3 4 8 4 8 5 8 5 9 0 4 1 4 1 5 1 5 6 5 6 9 Yes, the problem is that even for a cube the code is too…

Hey just wanted to see if you are aware of three’s ParametricGeometry class? Here’s a sphere function (generated by gpt) function parametricSphere(u, v) { const radius = 1.0; // Radius of the sphere const phi = u * Math.PI * 2; // azimuthal angle (around the y-axis) const theta …

Whoa cool.. didn’t know about that class. TIL :smiley:

Here my parametric cube, maybe it helps you. Try with resolution 100, 200, 300. https://codepen.io/Spiri0/pen/zxxvqYb?editors=0010 I’ve been thinking about making this an official threejs example.
