Surface from array of vector3

Hello, I have an array of points, how can I create a surface from these points similar to this image:

surface
surface1024×1024 27 KB

The array may contain more points not only 4, I want to extrude this surface after that but I can’t find the approach to construct this geometry. Any help is appreciated.

Maybe this will help you? :thinking:

NOTE! .addAttribute is now .setAttribute

You can’t derive a shape like shown in your image from a bunch of arbitrary points in 3D space. Assuming you have an array of 2D points AND they sequentially define the contour of a shape, you can use this array of points to create an instance of THREE.Shape. This shape can then be used to create an instance of THREE.ShapeBufferGeometry or THREE.ExtrudeBufferGeometry.

Thank you! these examples are exactly what I’m looking for :ok_hand:. that’s a huge collection of useful examples.

I’m glad if it’s usable for three.js users. :slightly_smiling_face:
