OB1- I saw the link, but never clicked.
ABF- Hidden surface removal is not a new idea. The techniques were developed in the 70s. It is simply impossible to create a 2D image with 3D objects any other way- you must find what objects are closest to the camera and draw them and that process is called hidden surface removal or visible surface determination. It's the same thing. Now maybe the older systems used a simple technique like a z-buffer instead of something a little more complex like a depth sort algorithm, but it is still hidden surface removal. If you want to learn about it, the best way I know is to read this book. It is the standard text in computer graphics, and is actually pretty easy to read.
