    Is there a way to take multiple video signals using GEM, sample only portions of them then recombine them into a single frame.

    For example I need to divide video into 4 separate sections across the screen, think of layers stacked on top of one another. the video will be sampled from multiple input streams such as camcorders. each camcorder covering a zone in the stack of video.

    so simply put can you select a region in the gem output to display. something like a layer mask?

    Does anyone know if puredata has a port started or completed for the PS3?

    I know not many people would be doing this but I am interested in seeing how well this would work.

    I just wanted to share a 16-step midi-trigger sequencer. I might not look nice but it works.

    I have been trying to find the best way to do this simple thing and I am looking for advice. I have a sub patch called selectMode which has 2 signal inlets and 1 number or message inlet for selection. The two signal inlets use one of 4 signal mathematical elements +~, -~, *~,or /~.

    Now i have attempted to use a few options to use only one of the 4 mixed outputs. The most logical seemed to be polygate~. However, I had no luck with that. Is there any anything similar to this function which would allow me to select 1 of X inputs for output?

    I am experincing a horible glitch/pop sound with any OSC~ function I use. I have read this could be a result of the frequencies amplitude being beyond the capabilities of the computer audio card. I am using a G4 powerbook, with Mac OS X 10.4.11. This sound is not present during the use of noise~

    any help with this would be great.

    Well yes I need to take 3 video signals and stack a section of them to form one body or image.

    for this id use 3 separate gemchains
    everyone looking like:

    [gemhead]
    I
    [translateXYZ] -- 0 -1 0 for 1st, 000 for 2nd, 0 1 0 for 3rd
    I
    [pix_video] -- device 1 - 3 or so
    I
    [pix_crop] (if needed)
    I
    [pix_texture]
    I
    [rectangle]

    Sonsofsol regarding [pix_crop]I am having issues with setting dimensions and offsets as there is no information on the sizes. I find that I usually end up with a crop that does not fit to the dimensions required or is not in the proper offset. Am I correct in saying that the dimensions of the capture source are not the same as the rectangle and/or Gem window? If not how do I correct for this issue or does the placement of the [pix_crop] before the [pix_texture] correct the problem I was having?

    Well yes I need to take 3 video signals and stack a section of them to form one body or image.

    so divide the image plane into 3rd's and put them one on top of the other. The idea is to have a section for head, torso, and legs, so they will be stacked vertically.

    [gemframebuffer] i am assuming is the entire buffer for that video frame? So could you unpack it as raw YUV / RGB data and recombine the sections into one frame or is there an easier way to do this?

    So I had some ideas should I be drawing everything into one [rectangle]
    Is there a way of taking the stream of data and just displaying that in sections so part 1 is lets use an arbitrary value of 4000 pix then part 2 is 4000 then part 3 is 4000, but have them display as a a hole in one rectangle?

    I am having some real issues with this. First I can't open the patch as it crashes right away. I am on a mac so I don't know if that is the difference.

    In my existing patch I can not get pix_crop to work properly. I can get multiple input streams USB and Firewire to test for now until I can get 2 more firewire cameras. The patch seams to have all the info I need but I just can't seem to stack the video the way I need to or get the crop to work at all.

    Bellow is my semi functional patch. Some things are hood up and others not as I am in the middle of testing it. But if you have any suggestions let me know.

    thanks for the tips. I was expecting the need for firewire cameras for some reason and the fire-i boards look fantastic, and have some lens options which will really help out for this project, of course price is always an issue but there pricing isn't bad.

    I'll give [pix_crop] a try sounds like exactly what I need to use.

    Sonsofsol: how did the project handle the 4 input streams? Did you encounter any issues with delay or latency?
