HemisphereLightHelper

创建一个虚拟的球形网格 Mesh 的辅助对象来模拟 半球形光源 HemisphereLight.

例子

var light = new THREE.HemisphereLight( 0xffffbb, 0x080820, 1 ); 
var helper = new THREE.HemisphereLightHelper( light, 5 ); 
scene.add( helper );

构造函数

HemisphereLightHelper( light : HemisphereLight, sphereSize : Number, color : Hex )

light -- 被模拟的光源.

size -- 用于模拟光源的网格尺寸.

color -- (可选的) 如果没有赋值辅助对象将使用光源的颜色.

属性

请到基类 Object3D 页面查看公共属性.

# .light : HemisphereLight

被模拟的半球形光源.

# .matrix : object

请参考半球形光源的世界矩阵 matrixWorld.

# .matrixAutoUpdate : object

请查看 Object3D.matrixAutoUpdate. 这里设置为 false 表示辅助对象 使用半球形光源的 matrixWorld.

# .color : hex

构造函数中传入的颜色值. 默认为 undefined. 如果改变该值, 辅助对象的颜色将在下一次 update 被调用时更新.

方法

请到基类 Object3D 页面查看公共方法.

# .dispose () : null

销毁该半球形光源辅助对象.

# .update () : null

更新辅助对象,与 .light 属性的位置和方向保持一致.
