Animation Techniques

Q In the PowerBook section of the Company Store demo, how do you get the animated Apple to move within the screen of the interactive PowerBook as you twirl it around?

A We shot several frames at each camera position, rather than just one. The paperblock Apple was actually displayed on the PowerBook's screen while we shot it. The camera took one image for each paperblock-Apple position. QuickTime VR takes care of the animation for you.
For more information, see points 8 and 9 of "Converting Objects" in Chapter 4 and "Creating Special Effects in Objects" in Chapter 19 of the QuickTime VR User's Guide.
