Hi, I am making a background for my website, and I would like it to be similar to: [image] With a wireframe load, I am getting: [image] Without wireframe, I am getting: [image] This is achieved using a simple smoothstep-shader where I take the y-coordinate of the vertex into account when creat…

Not that off-topic, as I used parts of three.js :sweat_smile:

Looks like it comes from this topic: Three.js + Delaunator The approach there uses an indexed buffer geometry, which is not suitable for the thing you want to achieve. I would cast the result geometry to non-indexed. And it needs to be done on every render. There are also options with fragment sh…

You are correct the initial Delunator comes from your post there. I see. If I understand you correct, you would simply take the meshIndices and pass them directly to a Shader instead of adding them to the existing point geometry using: g.setIndex(meshIndex); Would you still be able to use a THREE…

If you want just background, why not simply make it with canvas’ 2d-context. [изображение] Stuff used: Delaunaror, THREE.Vector2, THREE.Color, THREE.MathUtils, canvas.getContext(“2d”). Here, three.js used as a lib with helper classes/methods.

I have the feeling that a more faceted (flat shaded) appearance is needed? Something like this: Crystal planet [image]

You guys :sweat_smile: Good job both! I have other 3D objects in the scene, so maybe a combination of Pavel’s and Paul’s ideas will be the final result to avoid the 2D context but still get the desired effect. The idea is that this will be a backdrop running behind the other geometry. I am going to …
