...wow! thats a a lot more sophisticated than my approach! thanks!!! unfortunatly i can´t get "02.nfp-help.pd" patch to run and i´m not that much into this gl objects....
what are the error?
don´t get me wrong - i can also run GEM 0.92.3. but since after 0.90 versions mark danks "counter" object disappeared for no reason i still use 0.90 mostly. later version breaks about 90% of my old GEM patches.
counter disappear because there is no reason to include it in Gem. you can make a counter abstraction in few minutes. there are plenty of them. c
probably time to switch to vvvv and the multiscreen object/node/whatever...
it's sad to hear that you want to switch to vvvv because of a missing counter. c

I know, probably vvvv is the better choice to do this - but first i want to try it with GEM. i started with two screens, two pd instances, two gemwins framesynced over netsend/receive on one machine. for edgeblending i use pix_takealpha and a matching tif with alpha channel. > > > look at a thread named "soft edge" on this mailling list. > there a mail I send at then end of december that offer a patch that can do this kind of soft edge. > but you have to create only 1 windows that is on both screen. > (so you only have 1 pd) > > > at this point the first question appears: is there an object in GEM to adjust gamma and can elevate blacklevels ??? > i think everything that concern pixel value should be computed in Gpu (so with shader) for performance reason. > > > > > > for a rudimental imagewarping i textured the whole thing on a 4-point polygon. the next problem: on excessive warping poor edges appears on texturing - i´ve tried polygon_smooth but it seems that it does not do anything...is there a more elegant way to get smooth imagewarping??? > i recently upload a Gem example for doing this. > here it is. > > > > > > > > > thanks & best regards, > > > > rainer > > > > p.s. i´m still on GEM 0.90 > ??? > really? > according to files date, this release was made in 2004. > lot's of work have been made since. > it's time to upgrade. > > c > > > > > > > > > _______________________________________________ > > Pd-list@iem.at mailing list > > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
