hi,
about this thread comparing PDP and Gridflow, there's one thing good into having typed data is that they don't need expensive conversion whenever you want to use them in an i/o operation.
and i care about performance...
recently, a video artist also told me : "mm, jitter, yeh, that's about doing abstract math with images but i don't actually need to do that" ( and me neither ) so i don't think i'll go that way...
but, it's good to have different and complementary tools... so, stop the war.
cheers, sevy
