Display wireframe and solid color

Question

Is it possible to display the wireframe of the object and also the solid color of its faces on the same object? I found a way using a clone of the object and assign different materials e.g

var geometry = new THREE.PlaneGeometry(plane.width, plane.height,width - 1, height - 1); var materialWireframe = new THREE.MeshPhongMaterial({color:"red",wireframe:true}); var materialSolid = new THREE.MeshPhongMaterial({color:"green",wireframe:false}); var plane = new THREE.Mesh(geometry, materialWireframe ); var plane1 = plane.clone(); plane1.material = materialSolid ; plane1.material.needsUpdate = true; 

any thoughts?

To render both a model and its wireframe, you can use a pattern like this one:

// mesh var material = new THREE.MeshPhongMaterial( {     color: 0xff0000,     polygonOffset: true,     polygonOffsetFactor: 1, // positive value pushes polygon further away     polygonOffsetUnits: 1 } ); var mesh = new THREE.Mesh( geometry, material ); scene.add( mesh )  // wireframe var geo = new THREE.EdgesGeometry( mesh.geometry ); // or WireframeGeometry var mat = new THREE.LineBasicMaterial( { color: 0xffffff } ); var wireframe = new THREE.LineSegments( geo, mat ); mesh.add( wireframe ); 

The use of polygonOffset will help prevent z-fighting between the mesh material and the wireframe line. Consequently, the wireframe will look a lot better.
