Our Envision application* includes slideshow functionality with wipes and dissolves using NSImage / Quartz drawing. We'd like to switch to either QuickTime or OpenGL to do these transitions more efficiently. So far, it seems like either system is capable of displaying two static images and doing a transition from one to another. iPhoto uses OpenGL; I'm not sure which Keynote uses for it's lovely 3D transitions.
My impression is most people prefer OpenGL for this sort of thing, but QuickTime may be a great deal easier to code to (and may well use OpenGl itself). So why not do things the easy way and use QuickTime?
Thanks,
Paul Collins
