Generating indexed from non-indexed Geometry issue [SOLVED]

[Gangula]

The answer to this has been posted here:

BufferGeometry: toIndexed

Since i already posted the half snippet, this patches THREE.BufferGeometry with a function to create a indexed one from a non-indexed. A new BufferGeometry is returned. A indexed geometry reduces the data of all attributes and will generally perform better, also computeVertexNormals can be called only on indexed geometries to compute smooth normals.

Summary below:
Freystar has written a code that can be used to convert non-indexed to indexed geometry, BUT three.js has later implemented a method that can help with this called BufferGeometryUtils.mergeVertices() which is the recommended approach right now.

import * as BufferGeometryUtils from "three/examples/jsm/utils/BufferGeometryUtils.js";
