hi, i'm a totally newby to gem and pixel#world, but i have to do this exhibit with a friend of mine in which i'll play with pd and he's drawing on his mac with a graphic tablet (actually this is only one of the ideas).

Since i'm the only one who uses PD in the duo, i ask you:

• if it's possible to draw in pd as (or quite as...) in photoshop or similar?
• or better if there is a way to connect any osX drawing program to pd?
• there's a way to draw on a live cam-capture?
• and if there is a way to communicate (like netsend/netreceive) among the laptops?

thank's a lot for any advices

Here you go. Of course, with a tablet it could be much more involved. You could allow for the lifting and repositioning of the stylus, shape change based on pressure, color based on azimuth, etc.

This one contains a movie player, so you could do a similar w=thing with [pix_video] in place of [pix_film] for a webcam.

Look at pdp_pen object from pdp library (if u are not on windoz and use pd-extended you'll have it)

nestor, i've tried your etch-a-sketch: great work!!!
This is the patch i needed as starting point (now i'll try it also with [pix_video]).
Really thanks a lot.

husk, i appreciate your advice: maybe pdp_pen is better than the fake [gemtablet] given with gem. with some calm i will try it: only my alter-ego has a graphic tablet, so i'm pretty useless as tester...;(

due the richness of yours advices, i wait hopefully new ones.

The pleasure is all mine. You actually got me started down a new path with this question, I'm doing some further experimenting. I guess that is what is really great about this forum. One thing I DON't like about the patches I posted is that the framerate is limited by the grain-rate of the [gemmouse] object (which seems to send messages about every 20ms?) That is why the lines created 'trail' and have spaces between them. If your doing something abstract, that's kinda cool, but for representational sketching (as I'm sure your artist friend is used to) it doesn't work. I think the answer probably lies in [HID], so I'm gonna give that a whirl.

Here's another drawing patch, this time in double buffer mode.

WOW!!!!
i've no words. when i started this thread, my maximum expectations were some tips or hints, certainly not this.
i'll work hard as possible to use these hints as better as i can, i promise.

here my work in progress...

thanks to etch-a-sketch
