I’m trying to generate individual ice floes for a small low-poly game. I thought I could do this based on a cylinder, but unfortunately I don’t have the experience to know what values I need to use. Or is there a better way? let icefloeGeometry = new THREE.CylinderGeometry(0.3, 0.3, 0.5); // so…

[image] mindthegap: Or is there a better way? A cylinder is a good starting point. You might want to modify its vertices in order to make it more irregular.

Where can I find an introduction to vertices? I’m not sure which coordinates I would need to edit to, for example, pull a point slightly outward.

let icefloeGeometry = new THREE.CylinderGeometry(0.3, 0.3, 0.5,12,12); let vertices = icefloeGeometry.attributes.position.array; for(let i=0;i<vertices.length;i++) vertices[i]+=(Math.random()*.1)-.05; //Add some randomness to all verts icefloeGeometry.computeVertexNormals();

I’m not sure whether there are tutorials, maybe there are some somewhere. Most people learn by experimenting. Later on, I might draft a quick demo with the cylinder. Meanwhile, it might be possible to use convex geometry instead of cylinder. Edit: here it is with a cylinder, the low-poliness can be…

thank you very much, I will look into it in more detail

It could work like this, it doesn’t have to be interactive, but you can define the points.
