I'm interested is there some GEM object that manage single pixels on gem window?
Single pixel manipulation
hi maretom, i'm afraid native gem is not the best for this kind of things. try explaining better what you're trying to do and we'll see if it's possible to work something out.
Hi Guido !
thanks for quick answer !
i was wondering is it possible to simulate that effect when you have bad signal on your tv tuner, when you are watching tv on your computer.
you know that distortion and mixing and boosting of the colours....but not over the whole picture, just in some spots....
that's definitely not an easy thing to do with gem itself. how good are you at programming? i would suggest to give a look at glsl pixel shaders.
i agree with you. definitely it's not an easy thing in GEM....
I'm not specially good at programming I just generally understood basic concept...what ever it means....
I'll take a look at glsl pixel shaders.
oh, it is open gl....
yes, yes, I understand i can do that there, but currently, don't have time to learn that.
i did a quick research and this shader for max 5 does exactly what you are asking. it's rough but i'm pretty sure it'll work in gem right away.
Thank you guido !
I see your picture, that is the thing i'm looking for...
just,..... I never used max, so I have to ask what to do with this link you send to me?
From what you said, i concluded it should work in gem, but I never did such a thing in gem.
glsl shaders are interesting also because they run more or less everywhere you have gpu support, doesn't matter if webgl, max jitter or gem.
i quickly ported that shader to gem, give it a try. it should work right away on osx (only tested on 10.6.8 with gem 0.93.3)
update: test image added to the zip file now
Hi guido !
Thanks for the effort !
I tried to load your patch, but only manage to load [pix_shader].
other patch [analogGlitch] closes the PD with message "...bla, bla, pure data has stopped working, close the program ..."
I don't know what to do, I have that problem with loading many other gem help patches....
I opened topic about that problem on this forum but nobody answers....hehehe....
looks like a bug, the best thing would be to write directly to the mailing list. gem developers are really active there and will get back to you in a short time. subscribe here.
please be as precise as possible when describing the bugs and include the output you see in the pd console, if any. also don't forget to add informations about your platform (os, pd version, gem version).
Thanks guido !
