problem with [pix_mask]
by Jack 08 Nov '11

08 Nov '11

Hello, Is it normal that i get transparency when i use [pix_mask] in my example. It seems the white pixels from dancer.JPG are not enough white. Even with [pix_duotone] on dancer.JPG to get a white (1,1,1) and a black (0,0,0), it is still the same. Any idea to avoid this problem ? ++ Jack

pix_film inconsistency on out-of-range frames?
by Matteo Sisti Sette 28 Feb '11

28 Feb '11

Hi, If I connect [pix_film] to a white rectangle (via pix_texture), I've noticed that: - When I send pix_film a negative or zero frame number, it keeps showing the last valid frame it showed - When I send it a frame number greater than the number of frames the video has, the rectangle is shown solid white (I guess it means pix_film outputs an empty pix in this case). I don't know which of the two behaviors is best (I prefer the first one personally), however I think it should exhibit the same behavior in both cases... or not? I just wanted to make sure it is a bug before I file a bug report.

Category: Pixes (pix_ objects) Group: any operating system Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: pix_film prints an error msg if frame <0 but not if = 0 Initial Comment: This is a very minor issue, however... The right inlet of [pix_film] accepts a frame number which ranges from 1 to N if the video has N frames. If it receives a negative frame number, it prints an error message: error: [pix_film]: selection number must be > 0 To be consistent, it should print the same error message when it receives 0 as the frame number, but it doesn't. Indeed I thing the condition is actually that the frame be >=1 (consider floats!) Also I would suggest to specify in the help patch that the frame numbers start from 1 (unless I am the only one who would expect it to start from 0) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507079&aid=3195435&group_…

performance question with linux and nvidia
by cyrille henry 24 Feb '11

24 Feb '11

hello, i've got performance question regarding Gem an openGL. i made a test using an OS on a custom liveUSB, so that i can have the same software environment on 3 different computers: ubuntu 10.04, NVIDIA driver v270, pd vanilla 42.5, and Gem svn. this computer are: very old laptop: intel core 2 / GeforceGo 7700M old laptop: intel core 2 duo / Geforce 9650M gt new laptop: intel core i7 / Geforce GT 425M i made a test with glsl performance, and everything is normal : a newer computer is many time faster than the older. BUT, using a very simple patch (like attached), drawing only many time the same square, i can't see any really significant performance difference. how could that be? what can be the botleneck? (with "lighting 0", i can draw about 400 square before the fps goes down) but i've got a bigger problem : with "lighting 1", the 2 old laptop can draw about 10% less square (than with lighting 0). but the new one can draw only 3 times less square. So the new laptop is lot's slower than the old one when light is on. does anyone already experience something like this? any idea why, and how to solve this? thanks Cyrille

kinect camera object for Gem
by Hans-Christoph Steiner 19 Feb '11

19 Feb '11

Hey all, Joe Deken, the head of New Blankets, an NGO that's sponsoring some of my Pd work related to teaching, is interested in getting the kinect working with Pd. Anyone interested in hacking a gem object together? I know I can promise at least a long term loan of a kinect camera, more might be possible. [pix_kinect] would be awesome to have. .hc ---------------------------------------------------------------------------- "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

[pix_record] flip.
by Mathieu Bouchard 19 Feb '11

19 Feb '11

right now i'm trying [pix_record] and it seems to be recording everything upside down. This is regardless of the content of the upsidedown flag. [#to_pix] has an option to set the upsidedown flag. Toggling it causes [pix_texture] to flip the image, but [pix_record] encodes it upside down in both cases. It seems to be the same problem on both Linux and OSX. _______________________________________________________________________ | Mathieu Bouchard ---- tél: +1.514.383.3801 ---- Villeray, Montréal, QC
