fast resizing?
Feb 22nd, 2009, 5:48pm  
hey all,

i'm running a small GIF vj application based on my asus eee 900, and i'm getting an OK performance using low resolution (320x240). but if i scale up to my projectors lowest resolution 800x600, the framerate drops very much --- now i can live with the low resolution (the GIFs are already very lo-res) but i need high framerate.

is there a clever way to zoom a processing composition to fullscreen, which is FAST / lowlevel / openGL?

an example of the vj app running off a faster computer can be seen here: http://vimeo.com/2163427

the vj app is based on the gifAnimation library by extrapixel.

best,
jacob

oh, i should add that i tried making a PGraphics object for the gifs, drawing all my animations into that in 320x240, then scaling that to 800x600 when pasting it to the final composition. but this is REALLY slow, and also, it gives some graphics errors in the gif animations, along with soft / blurry resizing -- i want something that scales the pixels with hard edges, like the "nearest neighbour" setting in photoshop when resizing pictures....
