does anyone has an idea, how apple implemented
the zooming effect in the dock or the slide show
screen saver?
It is actually two OpenGL planes with the images as texture moving in
3D space. I have never used OpenGL, but I'm told this should be a
fairly simple task to implement.
In the case of the screensaver, yes, it's OpenGL-based (which is why
it's so slow on computers that Apple didn't bother to supply HW GL
acceleration drivers for), but I remember reading that the dock uses
some sort of custom algorithm that they were going to open up as a
public API but haven't gotten around to yet.
