reorderMesh optimal unique vertices for normal always facing outward.

[RyugaRyuzaki]

In threejs I have this :

const position = new Float32Array([....])
const normal= new Float32Array([....])
const index= new Uint32Array([....])

Those were not compressed or reordered.
Now i want to use

reorderMesh: (indices: Uint32Array, triangles: boolean, optsize: boolean) => [Uint32Array, number];

With output is the normal vector will be always facing outward likes these images .

How can i do it? Many thank!

Sorry, I'm not sure what you mean. reorderMesh has no relevance on the normal values, it only changes the order of vertices/triangles, and does so without changing the winding of triangles. If the screenshot you get is after reorderMesh, and it looks properly before it, then you have a bug in the code that calls it.
