Gem: the nVidia bug with pix_film
by Etienne Desautels 07 Aug '04

07 Aug '04

Hello list, a few weeks ago, I ask you about the bug with pix_film and the nVidia cards. Cgc told me that it was a know bug and suggest me to buy an ati card. It could be an option but I would really prefer if I can use my nvidia card. As I say before, I don't have the bug with pix_movie and I can correct it with pix_film by turning off an on the rendering of the gemwin after the movie is loaded. Also, I don't have the bug with the 0.87 version of gem. In view of this facts I was thinking that it could be surely be possible to find a way to avoid the bug. I did a few test by modifying gem and recompile it but without any success. But I'm far from a C++/openGL/carbon guru. I would really appreciate some help on this subject! Maybe I'm wrong but I feel it's probably just a small difference in the way the video is transfer to a texture between pix_movie and pix_film that avoid the bug in pix_movie and when I think about it I start having problem sleeping! Thanks Etienne

Re: [PD] render big tifŽs with GEM

hallo, wow! as you mention it, i remember a friend of mine who did the same with a 3d software (educational version), where the outputsize was limited to 640 x 480. i do a sort of actionpainting in single buffered mode with pix_data and noish~ as xy animators. so probably i get an immense amount of animation data to record. and if i change the camera viewport i have to rebuild the whole image (in single buffered mode). but most probably your idea is the only way to 4 x 3 meter images ;) do you have a prototype of your "render engine" to share? cheers rainer > >hallo rainer, > >i've used a somewhat virtual, non-realtime workaround, which simply >involves recording the 'animation' as a list (or preset sequence), >splitting the desired output size into multiple screensized >sections, rendering each individual section out, and moving the >cameras viewport to the limit of the last section.. then it's just a >matter of stitching the final image together in an image editor.. >it's not pretty but gets the desired results.. not too useful if you >are after realtime interference (but hey, who will ever know if it >never actually moves?) > >ciao.. >dmotd > > > _________________________________________________________________ Tired of spam?

GEM writing pix to image files
by thewade 06 Aug '04

06 Aug '04

Hello list! Ive been looking for a way to write snapshots of the gemwin to disk. Can anyone tell me what object to use? Ive been looking through the manual, and there sems to be a pix_snap for converting a screen capture to an image, but not writing it to a file. I could not find the manual entry for pix_write. Thanks for your help. -thewade Also, when I make a gem object, right-click, and select help I get nothing. What path element should I fix to get this to work? (winXP)

Re: [PD] Pd 0.37-2 released and denormals
by musil＠iem.at 05 Aug '04

Hi Miller pd-0.37-2 works fine under linux and has no more denormal-phenomenon. But the Windows version is badly compiled. You didn't #define __i386__ , so pd.exe don't use the #define of PD_BIGORSMALL in m_pd.h and the denormals still bug the decay of feedback loops. 2 files for testing denormals are attached: test-denormals.pd + fdbkloop.pd cheers , Thomas.

render big tifŽs with GEM
by rainer _ 05 Aug '04

05 Aug '04

hi, i just ask myself if it is possible to render bigger tif's than screen resolution? just have made a test with [dimen 4000 3000( and pix_write. the size of the rendered pix is 4000 x 3000, but the gem-pixels are only at the part where gemwin is clashing with my screen. the rest is black. i think about making c-prints out of some single-buffered gem pixel stuff. so if it's not hi-res (72 dpi) i need big dimensions. is this possible somehow? thanks rainer _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

Gem: problem sending dialog to pix_video on os X
by Etienne Desautels 04 Aug '04

04 Aug '04

Hi, I tried to use pix_video on os X with firewire DCAM (Fire-i by unibrain) and it works very well but if I tried to send a [dialog] to [pix_video] to configure the cam, the dialog appears and then PD freeze. I have to quit PD by hitting control-c in the terminal. I'm using os X 10.3.4 with pd 0.37 and gem 0.9. I would really like to be able to adjust the settings of the cam. Any ideas ??? Thanks Etienne

libquicktime and pdp
by Pall Thayer 04 Aug '04

04 Aug '04

'lo all, I'm having problems. Trying to install pdp+pidip on my linux (fedora core 2) laptop. I installed libquicktime from an rpm package from freshrpms. All went as it should. But when I try to ./configure pdp, it says it can't find lqt_decode_video. I've looked all over and this doesn't exist anywhere on my computer. libquicktime is in /usr/lib and contains a few lqt_whatever but no lqt_decode_video. Anyone know what this all means and how to remedy the situation?
