should we open a new category there ? or maybe that already exists and i missed it ? anybody else on this list that has some GEM shaders to share ?
lot's have already been send on this list!
i will recheck the archives. still, i think a central spot on the web containing GEM-ready shaders would be great, instead of having to dig through mailing lists.
if i have the time and do some more research i guess i'll start one on github
i have the feeling that a lot of people using GEM "roll their own" shaders (i, for one, did) and it would be a great thing to join forces, so one doesn't have to reinvent the wheel when looking for a simple "brightness/contrast" shader ...
funny, this one can be found in pd/help/browser/Gem/exemples/10.glsl/01.simple_texture.pd
haha, right. bad example ;-) so make that "looking for a simple [threshold] shader" ...
it's quite easy to use shader from shadertoy, at least when it's a single pass rendering.
thanks, i will do some research
the resulting texture seems to be 1x1 dimension. i'm sure the error is somewhere in the .vert part.
or texturing mode (rectangular or not)
tried that already, but it must be something else. anyway, thanks for all hints !
best
