Horizontal scrolling over pictures

vvvv beta general
#1

hi all

I have made a patch to scroll over pictures using a poti.
I render them on 5 quads and let the counter switch the pics when it is nog in view jet.
it all works but when I attach my dir-node to all the pictures (66 pics of 1024 x 768) the performance is VERY low.

I am not sure the quads are the right way to go, been looking to the slideshow patch and some other likely patches but cant really figure them out.

could anyone give me some advice?

Im working on a dual 2gig ram system and just purchased a radeon x1650 to speed up the performance

hope someone can give me some advice
attached my patch here

thanx in advance

ehm, you connected the counters to the BinSize pin of the GetSlice node… i guess you rather want to connect it to the Index pin.

furthermore it makes more sense to use only one FileTexture after the Dir (preloads all images) and use GetSlice (Node) to get the textures instead of switching the filenames (which causes a load on every switch).

There is certainly more than one way to achieve what you want.
The attached patch is only a quick (and probably buggy) hack but it should give you some ideas.

You should definitely learn (more) about spreads:
