车削几何体(LatheGeometry)

创建具有轴对称性的网格,比如花瓶。车削绕着Y轴来进行旋转。

// iOS iframe auto-resize workaround 
if ( /(iPad|iPhone|iPod)/g.test( navigator.userAgent ) ) { 
  var scene = document.getElementById( 'scene' ); 
  scene.style.width = getComputedStyle( scene ).width; 
  scene.style.height = getComputedStyle( scene ).height; 
  scene.setAttribute( 'scrolling', 'no' ); 
}

示例

var points = []; 
for ( var i = 0; i < 10; i ++ ) { 
  points.push( new THREE.Vector2( Math.sin( i * 0.2 ) * 10 + 5, ( i - 5 ) * 2 ) ); 
} 
var geometry = new THREE.LatheGeometry( points ); 
var material = new THREE.MeshBasicMaterial( { color: 0xffff00 } ); 
var lathe = new THREE.Mesh( geometry, material ); 
scene.add( lathe );

构造器

LatheGeometry(points : Array, segments : Integer, phiStart : Float, phiLength : Float)

points — 一个Vector2对象数组。每个点的X坐标必须大于0。
segments — 要生成的车削几何体圆周分段的数量,默认值是12。
phiStart — 以弧度表示的起始角度,默认值为0。
phiLength — 车削部分的弧度(0-2PI)范围,2PI将是一个完全闭合的、完整的车削几何体,小于2PI是部分车削。默认值是2PI。

基于参数创建一个LatheGeometry。

属性

# .parameters : Object

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。
