I search the forum about the teapot or target's postion.
And I have a question.
How can I get target's screen postion?
I know that the camera have three-dimensional.
But on the screen's coordinate have the x and y axis. No z axis.
So I should convert camera's coordinate to screen coordinate? Right?
I study the ImageTarget example. But in that code I can't find any solution.
Dose anyone can help me?
