Something wrong with "earcut"?

[ecojust]

Is there something wrong with “earcut” ???

Babylon.js Playground

In this PG , if you change line 15 createMesh1 to createMesh2,

you can find that , If the points given are in the xoz plane, the graph cannot be drawn correctly

Or maybe Earcut has some rules that I don’t know about

Or you could help me fix the case

Earcut is an external library so I’d recommend asking there mapbox/earcut: The fastest and smallest JavaScript polygon triangulation library for your WebGL apps (github.com)
