Usage

var removeOrphanVertices = require('remove-orphan-vertices');
 
var mesh = { 
  cells: [
    [0, 2, 3]
  ],
  positions: [ 
    [0, 0, 0],
    [1, 0, 0], // <- unused
    [1, 0, 0],
    [0, 1, 0],
    [0, 0, 0]  // <- unused
  ] 
}
 
mesh = removeOrphanVertices(mesh.cells, mesh.positions);
 
console.log(mesh);
