I currently have a set of vectors and would like to perform triangulation. I know there’s earcut but it only performs on 2D. My question is the following: if I have a custom shape or a set of vectors how can I get all… --- ## [3D triangulation](https://discourse.threejs.org/t/3d-triangulation/64420)

Hello, I implemented a 2D triangulation fonction using Earcut. This isn’t the result I want because I want to triangulate 3D polygons (because rotations etc are computed somewhere else in the backend and I can’t access … --- ## [Get non-triangulated faces when import 3D model](https://discourse.threejs.org/t/get-non-triangulated-faces-when-import-3d-model/50560)
