How to load ply files dynamically rather than go and change source code everytime?

            loader.load( 'model/S002_001.ply', function ( geometry ) {
                geometry.computeVertexNormals();
                var material = new THREE.MeshStandardMaterial( { color: 0x0055ff, flatShading: true } );
                var mesh = new THREE.Mesh( geometry, material );
               // mesh.position.x =  -0.2;
                mesh.position.y =  0.45;
                mesh.position.z =  0;
                mesh.rotation.x = - Math.PI / 2;
                mesh.scale.multiplyScalar( 0.6 );
                mesh.castShadow = true;
               // mesh.receiveShadow = true;
                scene.add( mesh );
            } );

//here instead of loading file statically.can i change the file path in runtime?

You can wrap this code in a function with some parameters of the path, position, rotation, scale and material.
