hi peter,<br><br>great!!! please let me know when you are finished with this toolkit - and yes, probably we could talk german also :)<br><br>basic softedging with alphablending was not the problem in GEM - at least i stumbeld over the polygon/imagewarping/texturing problem. as i said - i´m not that much into gl coding. i wonder why there is no such basic object like "mesh" in GEM (i know there is mesh_square and ripple)<br><br>i have to say, vvvv is much more advanced in this case.<br><br>cheers,<br><br>rainer<br><br><br>> Date: Thu, 17 Feb 2011 21:59:52 +0100<br>> From: mail@petervenus.de<br>> To: jepoxy@hotmail.com<br>> Subject: Re: [PD] GEM - edge blending and polygon smooth<br>> <br>> <br>> Hello Rainer!<br>> i suppose i could talk in German to you, , but<br>> anyhow:<br>> as cyrille mentioned, there is a thread regarding softedge of images.<br>> in fact, i just finished a multiscreen/projector toolkit with pd,<br>> even though vvvv seems more natural for that.<br>> i will release this toolkit, which is basically a set of abstractions<br>> within the next 3 to 4 days officially(still working on the documentation)<br>> the toolkit is basically built around openGL shader, which are managing<br>> the imagewarping.<br>> so maybe that toolkit would be what you are looking for, so a little patience :)<br>> peter<br>> <br>> <br>> <br>> <br>> ---------------------<br>> Von: "rainer _" <br>> Gesendet: 16.02.2011 13:43:17<br>> An: pd-list@iem.at<br>> Betreff: [PD] GEM - edge blending and polygon smooth<br>> <br>> <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>> at this point the first question appears: is there an object in GEM to adjust gamma and can elevate blacklevels ???<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>> <br>> <br>> thanks & best regards,<br>> <br>> rainer<br>> <br>> p.s. i´m still on GEM 0.90<br> </body>
