I'm currently transforming some objects to make them appear far away using a PerspectiveTransform . 我目前正在使用PerspectiveTransform变换一些对象，使它们看起来很远。 This works well, but I have no way of knowing where on the screen the object is displayed. 这很好用，但是我无法知道对象在屏幕上的何处显示。 The x and y coordinates are the coordinates of the object if it were at z=0 . x和y坐标是对象在z=0处的坐标。 How can I compute the display coordinates of my component? 如何计算组件的显示坐标？

What about the flash.display.DisplayObject 's localToGlobal and globalToLocal methods? 那flash.display.DisplayObject的localToGlobal和globalToLocal方法呢？ Each takes a point from the first space and returns a transformed point in the second space. 每个都从第一个空间获取一个点，然后在第二个空间中返回一个变换的点。

EDIT: 编辑：

Also see the local3DtoGlobal and globalToLocal3D methods for 3D transformations. 另请参阅用于3D转换的local3DtoGlobal和globalToLocal3D方法。
