What are the coordinates of a display object that has been transformed with a PerspectiveProjection?

Question

I'm currently transforming some objects to make them appear far away using a PerspectiveTransform. This works well, but I have no way of knowing where on the screen the object is displayed. The x and y coordinates are the coordinates of the object if it were at z=0. How can I compute the display coordinates of my component?

Answer 1

What about the flash.display.DisplayObject's localToGlobal and globalToLocal methods? Each takes a point from the first space and returns a transformed point in the second space.

EDIT:

Also see the local3DtoGlobal and globalToLocal3D methods for 3D transformations.
