使用矢量3的参数几何

var restDistance = 20;
var xSegs = 15;
var ySegs = 10;

var clothFunction = plane(restDistance * xSegs, restDistance * ySegs, zSegs);
var cloth = new Cloth(xSegs, ySegs);

clothGeometry = new THREE.ParametricGeometry( clothFunction, cloth.w, cloth.h, true );

var clothFunction = function (u, v) {
                return new THREE.Vector3(restDistance * xSegs, restDistance * ySegs, 1);
            };
