03 Feb '09

hello, can anybody please tell me how can i make this little script in Gem? this script is made in Mel , the maya embedded language, the idea to use the remainder operation or module "%" to create repetition at variable distances, we can use this to create rhythm or patterns.... thanks in advance for ($x= 0; $x<40; $x++){ if($x%5==0) continue; Sphere 2; translateXYZ ($x*2) 0 0; } Other question which other ways do there are to create patterns with module? thanks pun.

re all, maybe my pd has a problem with streaming. i used a giss.tv v4l2 patch [attached] my software is pd-extended 0.40.3-intrepid6. when i started the streaming, pd returned this: *** buffer overflow detected ***: pd terminated ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6(__fortify_fail+0x48)[0xb7da4558] /lib/tls/i686/cmov/libc.so.6[0xb7da2680] /lib/tls/i686/cmov/libc.so.6[0xb7da1d68] /lib/tls/i686/cmov/libc.so.6(_IO_default_xsputn+0xc8)[0xb7d17a18] /lib/tls/i686/cmov/libc.so.6(_IO_vfprintf+0x3733)[0xb7ced0c3] /lib/tls/i686/cmov/libc.so.6(__vsprintf_chk+0xa7)[0xb7da1e17] /lib/tls/i686/cmov/libc.so.6(__sprintf_chk+0x2d)[0xb7da1d5d] /usr/lib/pd/extra/pidip.pd_linux[0xb6e5802f] [0xa0c1e98] any sugestion? grettings. -- Ricardo Brazileiro ^ ~ http://rbrazileiro.info

Re: [PD] MetaVJ
by Ed Kelly 03 Feb '09

03 Feb '09

Hey, er...um... Well, I'm having an "interesting" year, so development is going pretty slowly!! But, I send you a zip of the MetaVJ without any documentation. I'm trying to finish the docs and new features for Metastudio 0.3 before I release MetaVJ - a bit busy with marking my students' work and...sand. Well good luck. I think mid February is probably the release for both Metastudio 0.3 and MetaVJ 0.1, but I might be jumping the gun again - things are afoot....! Best wishes - and please report any bugs - things that go uninitialized. i.e.: Something doesn't work before you hit a particular switch... Problems with PD-extended (but please, only the latest release version - 0.40.3) No video output (but maybe you need to try pdp_glx if you have a shared-memory video chip). I am not performing right now with it because my Dell, with the NVidia proprietary drivers crashes pdp when it's displayed on an external monitor/projector...can anybody tell me why? or how to fix this???

5.1 Surround Sound, vbap.
by narbino＠ucsd.edu 03 Feb '09

03 Feb '09

Hello- I am doing an installation with a reactable that I am building. The only difference is that I am making the glass table top spin. Depending on which way the table spins the noise will travel through 5.1 surround sound accordingly. Ex. if the table spins to the right the music will spin through the speakers to the right and if it spins to the left, music will also spin to the left. My question is: does anyone have a working 5.1 surround sound patch that I could look at? Someone suggested vbap. I also heard there is an object called pix_fiducialtrack or something similar? Does anyone know anything about this? I would really appreciate some information. Thank you -Natalie Arbino

Optimisation - Max & PD
by Daniel Bennett 02 Feb '09

02 Feb '09

There's been a lot of talk here of late about PD not being terribly well optimised in lots of ways - GUI drawing, and potentially other areas. I'd always assumed (naively) that being less impressive to look at, PD was probably quicker (in equivalent circumstances) than MAX. As such, (and not having much cash for high powered PCs or software) when I came to pick between MAX and PD, I picked PD. Was I wrong in assuming that PD runs more efficiently than MAX (specifically on XP)? I'm not sure I can afford MAX anyway, so the question is pretty much academic, but I'm interested to know peoples' thoughts on the matter. Especially as I've recently come up against PD's issues with Midi inputs on XP (screws my shutdown every time I try to use midi inputs). Ta Dan -- Geometer Magazine http://geometer.org.uk

dynamically altering GUI send/receive symbols
by Rory Walsh 02 Feb '09

02 Feb '09

Quick question: is it possible to dynamically alter the send/receive symbols for GUI objects? I know that one can change most attributes through various messages but is it possible to alter their send/receive symbols? Rory. p.s. It's been a few years since I posted any messages here. I hope everyone is keeping well!
