new test windows dll
by chris clepper 25 Apr '06

25 Apr '06

I just put up a new dll that hopefully does not need the extra runtime lib DLLs. Can someone try it? http://taproot.dyndns.org/~cgc/downloads/Gem.dll

anyone have a recent G5 OSX binary? WAS: testing the position of a gem chain
by B. Bogart 24 Apr '06

Thanks Chris, So its a new object, anyone have a G5 Gem binary that includes gemlist_info I can use? I tried both binaries on tigital's mac homepage, but I can get neither to load in PD. (no errors, just "can't load library") I'm running 10.3.9...

...just came across this project, and thought it might be helpful to look at for dealing with our windows video code: we're already on the same page as far as the osx code goes (it's based on daniel's "seesaw" code)... http://www.iua.upf.es/mtg/reacTable/PortVideo/ http://sourceforge.net/projects/portvideo/ jamie

building gem
by Tim Blechmann 11 Apr '06

hi all, building gem on gentoo fails, because of inclusion of GL/glext.h. on gentoo the locations of glext.h instances are: /usr/lib/opengl/nvidia/include/glext.h /usr/lib/opengl/xorg-x11/include/glext.h it might be better to add the GL path to the include folders and only include glext.h ... makes it more portable ... cheers ... tim -- TimBlechmann(a)gmx.de ICQ: 96771783 http://www.mokabar.tk A paranoid is a man who knows a little of what's going on.

OSX installation - PD CPU usage...
by B. Bogart 05 Apr '06

05 Apr '06

Hi Chris and Jamie, So I was able to downgrade quicktime to 6.5 by: Finding and installing the 7.0.1 reinstaller for 7.0.4 Finding and installing the 6.5.2 reinstaller for 7.0.1 You cannot install 6.5.2 from 7.0.4 directly. I tested 7.0.1 as well, and indeed it behaves exactly the same as 7.0.4 so those shark tests should be good fodder for apple to fix quicktime. Yes using qt 6.5.2 I can play my 16 clips simultaneously for days without the damn "mentor" getting in the way. I guess playing this many clips through quicktime is not often done, otherwise I would have thought the bug would have been found in 7.0.1 and not stick around to 7.0.4. Thanks for your help Chris, This thread is now resolved. .b.

How to change perspective Angle in Gem : WAS gemwin "view" message
by B. Bogart 04 Apr '06

04 Apr '06

Hey all, Anyhow I tried another approach to my setup so that all the three virtual cameras require the same lens, but alas it still does not work since the default lens of the camera does not match what I would like. A quick run down of what I'm doing: I have a (physical) space with three rear-projection screens. I want to have three gemwins (on different machines) that each sees the gemworld from the view of each of these physical screens. They are fixed in space, surrounding a room at angles (see attached filen which shows the view of the room from the top). Basically the virtual gem-space is then mapped into the physical space on multiple screens. (cave-like, but of course not a cube of screens) So its easy enough to get the camera to point at the center of each virtual screen, but the edges of the screen don't match the edges of the gemwin. (in the attached OOo diagram we should see only the red square in screen 2, and the green square in screen 3, but both the red and green squares are visible in both screen 2 and screen 3. Method-A and Method-B slides show the two options for the camera views, in option A the camera plane is parallel to the screen plane, but the distances from camera to screen are different. In method-B the camera is the same distance from all the screens, but for screen 2 and 3 the camera plane is not parallel to the screen plane. Also I included a few attached patches: virtual-camera-test2 is method-A virtual-camera-test3 is method-B. I'd really like to get this resolved, since we're hoping to do many gem-projects in this space with these three screens... Thanks all, .b.

Pix_levels
by Peter Forde 04 Apr '06

Does anyone have a simple explanation of how to control pix_levels. I don't understand the floor and ceiling stuff. Basically I need to kill the reds or greens in a particular gemhead. Similar to a channel mixer. Thanks Peter

rstp video in GEM
by Adrien Mondot 01 Apr '06

01 Apr '06

Hi here, I'm working on a live stage performance mixing juggling and computer arts, I've already worked a little bit with gem. For a project using a 100 fps IP-camera (check http://www2.elphel.com/index.html) , I'm looking for a way to use a streamed video in gem. Although I know it would be better to use pdp for this kind of stuff, most of the patch is already done in GEM (with a 25 fps DV cam), and it would be a pain in the ass to make it from scratch in pdp. The problem is : I can encapsulate the stream in a .mov file in order to make QT think it is a local file, but the pix_film object is unable to load the frame in it (while QT, Quartz Composer or other QT-based application can do it). any ideas of a solution ? I'm using a PowerBook G4 with OS 10.4.5, Pd-0.39-2 from Miller and GEM-CVS (11/05) To give an idea of what we are looking to do, here is a video of the patch with the DV-Cam http://video.adrienm.net/LaboReTime.avi PS : excuse for my poor english... _________________ www.adrienm.net "Et avec quelle quantité d'illusions ai-je dû naitre pour pouvoir en perdre une chaque jour ?"
