生成由参数表示其表面的几何体。
var geometry = new v3d.ParametricBufferGeometry(v3d.ParametricGeometries.klein, 25, 25);
var material = new v3d.MeshBasicMaterial({ color: 0x00ff00 });
var klein = new v3d.Mesh(geometry, material);
scene.add(klein);
func — A function that takes in a [page:Float u] and [page:Float v] value each between 0 and 1 and modifies a third [page:Vector3] argument
slices — The count of slices to use for the parametric function
stacks — The count of stacks to use for the parametric function
一个包含着构造函数中每个参数的对象。在对象实例化之后,对该属性的任何修改都不会改变这个几何体。
