Re: [PD] GEM - edge blending and polygon smooth

hi peter,

great!!! please let me know when you are finished with this toolkit - and yes, probably we could talk german also :)

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)

i have to say, vvvv is much more advanced in this case.

cheers,

rainer

Hello Rainer! i suppose i could talk in German to you, , but anyhow: as cyrille mentioned, there is a thread regarding softedge of images. in fact, i just finished a multiscreen/projector toolkit with pd, even though vvvv seems more natural for that. i will release this toolkit, which is basically a set of abstractions within the next 3 to 4 days officially(still working on the documentation) the toolkit is basically built around openGL shader, which are managing the imagewarping. so maybe that toolkit would be what you are looking for, so a little patience :) peter

hi,

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.

at this point the first question appears: is there an object in GEM to adjust gamma and can elevate blacklevels ???

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???

thanks & best regards,

rainer

p.s. i´m still on GEM 0.90
