i am surprised, that you got even a result with [translateXYZ]-[pix_draw]. something very important to know about Gem is, that you can work in two domains: in the openGl-domain, which is completely processed on the gpu (if supported by hardware and enabled) and in the pix domain, which is computed on the cpu. all objects of gem with pix_* in their name belong to the pix domain. what cyrilly is proposing , is to switch as soon as possible to the opengl domain in order to save cpu, since [pix_draw] usually is quite slow (with [pix_draw] you get the very same result while just burning some cpu cycles). > cyrille > > > > oh, and is there a way to plot large image files with [pix_texture]? > > i'm trying to do something like this: > > http://shiraklasmerphotography.com/Flash_Move/movement3.htm yeah, this is perfectly possible with the patch, that cyrille proposed. nevertheless, there are probably some hardware limitations. at least on my box, i wasn't able to texture a picture with a width of 3000px. i splitted it into 3 files à 1000px and textured them separately on three rectangles. let me know, if cannot figure out to do it, i can send you the patch. roman ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
