Away3D 4.x 更改投影中心

如何使用 perspectiveLens 更改 Away3D 中的投影中心。

我知道可以使用标准 flash 3d 库来完成，使用：

root.transform.perspectiveProjection.projectionCenter = new Point(center.x, center.y);

但是在查看 Away3D 类时不存在这样的函数。
away3D是否通过其他方法实现了这一点？

How to alter the projection center in Away3D using a perspectiveLens.

I know it can be done with the standard flash 3d library, using:

root.transform.perspectiveProjection.projectionCenter = new Point(center.x, center.y);

But no such function exists when looking into the Away3D classes.
Does away3D achieve this by using another method?

Object3d 或任何从它衍生的东西确实有“pivotPoint”。

但通常您只想移动相机。

camera.z = -1000;
camera.x = 500;
camera.y = 500;

// after moving the camera you'll want to re-orient towards your scene.
//for instance to look at the origin:
camera.lookAt( new Vector3D(0,0,0));

编辑：
如果您只是想旋转一个对象，请尝试 pan()、pitch() 和 roll()。

Object3d or anything that descends from it does have 'pivotPoint'.

But usually you'll just want to move your camera around.

camera.z = -1000;
camera.x = 500;
camera.y = 500;

// after moving the camera you'll want to re-orient towards your scene.
//for instance to look at the origin:
camera.lookAt( new Vector3D(0,0,0));

edit:
If you're just trying to rotate an object try pan() pitch() and roll().
