i posted this message a week ago but got no response, perhaps because
of the holidays. So, here i go again:
Does anyone know how to reproduce the fast image loading and scrolling
that iPhoto 4 has? I mean, displaying a low res version while
scrolling and resizing is one thing, but how does one implement this?
What could be the tricks behind this?
For now, I have created my own custom row/column view that works
great, like the way it was in previous versions of iPhoto, but i am
eager to learn the technique used to create that damn fast loading,
scrolling and even resizing.
Any suggestions or experiences?
I believe iPhoto uses OpenGL. During scrolling, output quality is
decreased so that rendering time is greatly reduced. It's probably
some trick with textures. Someone that actually has dealt with OpenGL
(I never have myself) will know for sure.
