Will three.js Object3D.clone() create a deep copy of the geometry?

Question

I\'m loading models using the collada loader. The loader returns an Object3D, \"dae\", with many child meshes. I\'d like to instantiate the parent \"dae\" object many times

Answer 1

Here is a couple of function I use to clone object's materials deeply. You could modify this to your needs

Also consider this information : https://github.com/mrdoob/three.js/issues/5754

    /** Gives the aptitude for an object3D to clone recursively with its material cloned (normal clone does not clone material)*/

    THREE.Object3D.prototype.GdeepCloneMaterials = function() {
        var object = this.clone( new THREE.Object3D(), false );

        for ( var i = 0; i < this.children.length; i++ ) {

            var child = this.children[ i ];
            if ( child.GdeepCloneMaterials ) {
                object.add( child.GdeepCloneMaterials() );
            } else {
                object.add( child.clone() );
            }

        }
        return object;
    };

    THREE.Mesh.prototype.GdeepCloneMaterials = function( object, recursive ) {
        if ( object === undefined ) {
            object = new THREE.Mesh( this.geometry, this.material.clone() );
        }

        THREE.Object3D.prototype.GdeepCloneMaterials.call( this, object, recursive );

        return object;
    };
