Three.JS wireframe material - all polygons vs. just edges
If you want to render a wireframe of a given geometry, you can now use this pattern:
var geo = new THREE.EdgesGeometry( geometry ); // or WireframeGeometry( geometry )var mat = new THREE.LineBasicMaterial( { color: 0xffffff, linewidth: 2 } );var wireframe = new THREE.LineSegments( geo, mat );scene.add( wireframe );WireframeGeometry will render all edges. EdgesGeometry will render the hard edges only.
Also see this related answer on how to render both a model and its wireframe.
