问题描述
我需要将轨迹球控件和相机与定向灯同步.
I need to sync trackball controls and camera with the directional light.
我的案例:用相机、灯光和控件初始化一个空场景.加载一个 bufferGeometry obj，获取它的质心并设置相机并控制相对于 obj 质心的位置和目标.基本上我只是简单地设置相机位置和 control.target :
My case scenario:Init an empty scene with camera, lights and controls.Load a bufferGeometry obj, get its centroid and set camera and controls position and target relative to the obj centroid.Basically I simply set camera position and controls.target with:
camera.lookAt( position );
camera.position = position;
controls.target.copy( position );
其中 position 是一个 Three.Vector3 对象.
where position is a Three.Vector3 obj.
定向光必须与控件自动同步.
Directional light has to sync automatically with controls.
我使用threejs r66做到了:
I did it using threejs r66:
function init(){
...
directionalLight.position = controls.object.position;
directionalLight.target.position = controls.target;
...
}
其中控件是一个 THREE.TrackballControls 对象.
where controls is a THREE.TrackballControls object.
使用threejs r69 不再起作用.有什么建议吗?
With threejs r69 does not work anymore.Any suggestions?
谢谢，

使用 pointLight 而不是 directionalLight 解决.
Solved using a pointLight instead a directionalLight.
var pointLight = new THREE.PointLight(0xffffff, 1, 100);相机.添加(点光源)；
var pointLight = new THREE.PointLight( 0xffffff, 1, 100 );camera.add( pointLight );
感谢大家的帮助
推荐答案
解决方案(感谢 WestLangley)是:
The solution ( thanks to WestLangley ) is:
var pointLight = new THREE.PointLight( 0xffffff, 1, 100 );
camera.add( pointLight );
