向几何体添加细分 [英] Add subdivision to a geometry

问题描述

我正在尝试向这样的球体添加细分:

I'm trying add subdivisions to a sphere like this:

http://stemkoski.github.com/Three.js/Subdivision-立方体.html

这是我的代码:http://jsfiddle.net/mdrorum/HvFLw/

        <script src="http://mrdoob.github.com/three.js/build/three.js"></script>

            <script type="text/javascript">

            var camera, scene, renderer;
            var geometry, material, mesh;
            var smooth, subdiv, modifier;

            init();
            animate();

            function init() {

                camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 1, 10000 );
                camera.position.z = 1000;

                scene = new THREE.Scene();

                renderer = new THREE.CanvasRenderer();
                renderer.setSize( window.innerWidth, window.innerHeight );

                document.body.appendChild( renderer.domElement );

                geometry = new THREE.SphereGeometry( 200 );
                material = new THREE.MeshBasicMaterial( { color: 0x00ff00, wireframe: true } );

                mesh = new THREE.Mesh( geometry, material );
                scene.add( mesh );

                var smooth = mesh.clone();
                var subdiv = 3;
                var modifier = new THREE.SubdivisionModifier( subdiv );
                //modifier.modify( smooth );


            }

            function animate() {

                requestAnimationFrame( animate );

                mesh.rotation.x += 0.01;
                mesh.rotation.y += 0.02;

                renderer.render( scene, camera );

            }

        </script>

这很好用，但取消注释://modifier.modify( smooth );

This works fine, but uncomment: //modifier.modify( smooth );

什么都没发生.:(

如何添加细分?

推荐答案

您正在尝试修改 mesh.你需要修改一个geometry.

You are trying to modify a mesh. You need to modify a geometry.

modifier.modify( geometry );
