...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....<br><br>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.<br><br>probably time to switch to vvvv and the multiscreen object/node/whatever...<br><br>thanks again,<br><br>ra<br><br><br><br>> Date: Wed, 16 Feb 2011 17:45:32 +0100<br>> From: ch@chnry.net<br>> To: jepoxy@hotmail.com<br>> CC: pd-list@iem.at<br>> Subject: Re: [PD] GEM - edge blending and polygon smooth<br>> <br>> hello,<br>> <br>> Le 16/02/2011 13:43, rainer _ a écrit :<br>> > hi,<br>> ><br>> > i´m currently working on a patch for a multiscreen / multiprojector installation. 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.<br>> ><br>> look at a thread named "soft edge" on this mailling list.<br>> there a mail I send at then end of december that offer a patch that can do this kind of soft edge.<br>> but you have to create only 1 windows that is on both screen.<br>> (so you only have 1 pd)<br>> <br>> > at this point the first question appears: is there an object in GEM to adjust gamma and can elevate blacklevels ???<br>> i think everything that concern pixel value should be computed in Gpu (so with shader) for performance reason.<br>> <br>> <br>> ><br>> > 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???<br>> i recently upload a Gem example for doing this.<br>> here it is.<br>> <br>> <br>> <br>> ><br>> ><br>> > thanks & best regards,<br>> ><br>> > rainer<br>> ><br>> > p.s. i´m still on GEM 0.90<br>> ???<br>> really?<br>> according to files date, this release was made in 2004.<br>> lot's of work have been made since.<br>> it's time to upgrade.<br>> <br>> c<br>> <br>> ><br>> ><br>> ><br>> > _______________________________________________<br>> > Pd-list@iem.at mailing list<br>> > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list<br> </body>
