我需要同步轨迹球控制和摄像头的定向光。

I need to sync trackball controls and camera with the directional light.

我的情况： INIT相机，灯光和控制一个空的场景。 加载bufferGeometry物镜，获得它的质心，并设置摄像机和控制位置和目标相对于所述物镜的质心。 基本上，我简单地设置摄像机的位置和controls.target有：

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 );

，其中位置是Three.Vector3 OBJ。

where position is a Three.Vector3 obj.

定向光有与控制自动同步。

Directional light has to sync automatically with controls.

我做到了用threejs R66：

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不再工作了。 有什么建议？

With threejs r69 does not work anymore. Any suggestions?

谢谢

使用点光源，而不是DirectionalLight的解决。

Solved using a pointLight instead a directionalLight.

变种POINTLIGHT =新THREE.PointLight（0XFFFFFF，1，100）; camera.add（点光源）;

var pointLight = new THREE.PointLight( 0xffffff, 1, 100 ); camera.add( pointLight );

感谢所有帮助

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 );
