[PD] GEM - edge blending and polygon smooth

[rainer _]

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
