Isadora 3 - Status Report from Mark



  • @mrtz said:

    Dear Mark,


    With regards to the $1500 PC you mentioned ”that leaves Apple in the dust”:  Can you please tell us which brand and model it is? If it is a Mini PC, is there one capable of 4 full hd outputs for projectors and a 5th one for a controlling screen?
    And one final question: I used a Radeon Vega 56 in a Sonnet 650 eGPU for the show, the four outputs worked but I had the impression that the card was not faster than my internal Macbook Pros Radeon 560X at all, maybe even a bit slower.
    However, I remember you said that Isadora cannot use the eGPUs additional power at the moment. But then I thought: it is not that the eGPU did not work at all, as the four outputs worked, it´s more that it just was not as fast as I had expected. Will Isadora 3 be able to take more advantage of an eGPU?
    Thanks,
    Moritz

     You have a GPU you know does 4 outputs and to get your 4+1 make sure the CPU you buy has an integrated GPU as you could then get your +1 output from the motherboard video output. The other option is to run 2x GPUs the second could be a really inexpensive one solely for the control screen.

    eGPUs are a bit of a waste of time as the TB3 bus speed is the limiting factor compared to a GPU attached to an internal 16x PCIe bus obviously if you are driving 4 screens at a decent frame rate that's a fair amount of bandwidth required plus overhead. You have to be careful too as these eGPU TB3 ports share the same PCIe bus, e.g. the new Mac mini has 4x TB3 ports but I'm told they all share the same 4x PCIe bus which makes a mockery of actually having 4 ports.



  • Massive work mark. I Can't wait to test it with my massive new config. I9 pc with Blackmagic Decklin 4k extreme 12g!!



  • These all new features are my dream!

    I can see a lot of possibilities now, good job team!



  • @mark

    It' look grate. I'm impatient to try. 

    Whishing you good job to achiueve this release.

    Best rgard

  • Thanks Mark. This is so exciting. there are features here we briefly talked about years ago now coming to fruition. I'm already planning my own projects but am also going to set up an immersion/interactivity research lab here in Shanghai based around this. The new pricing structure should also help broaden this into a full blown course. BRAVO!!

    Exciting.  @Mark, how did you get around NiTE's licensing restrictions, which prohibit using it with non-Primesense devices and prohibit redistributing it?

    Uh, well, I guess I wasn't aware of that particular restriction. From that license agreement:

    You shall not (and shall not permit third parties to): (a) integrate the NITE with any products other than the Authorized Hardware; (b) distribute the NITE in any manner; (c) use or make available the NITE pursuant to an open source license; (d) modify the NITE;

    There are other drivers out there (libfreenect2) that allow you to use NITE with Kinect 2, which is not a Prime Sense device, which is in violation of clause (a).

    Obviously Processing, NI Mate and others are distributing the library, which is in direct violation of the clause (b)

    I would guess that this github is in violation of clause (d) because it includes NITE.

    In other words, there Prime Sense (which was bought up by Apple) don't seem to be enforcing this or going after people. They don't even have a website anymore (the URL www.openni.org reroutes to Apple.) But, now that I'm aware of this, we may simply have to ask people to install NITE themselves if they wish to use that part of the system.

    We will investigate further.

    Best Wishes,
    Mark

    How can this be considered evidence of a current license? It appears to be linked to a the Internet Archive's capture of a discontinued Openni website dating from 2014. There appears to be no directly accessible current/active reference to the functioning Openni.org enterprise or the licensing agreement that is referenced in the archive.

    It appears a bit harsh to sign up to this form and drop what appears to be a redundant licensing clause without pointing to current information or specifications.

    Please correct me if I am wrong.

    best wishes

  • That's the most up-to-date NiTE licensing information available, since Apple took down the website.

    I just don't want to see TroikaTronix sued by Apple's less-than-magnanimous legal team — that would be bad for all of us.

    Well, I appreciate knowing this actually. We have to take care with these things. I mean, it super easy to install NiTE on MacOS using Homebrew, and just a tiny bit more tricky on Windows (though it could probably be handled by a script.) If we force the users to install it then I think we're safe. (Homebrew, by the way is another indication about this: https://github.com/totakke/hom...)

    Still, I'll write on the github for the Processing plugin I mentioned above and see what they say.

    Best Wishes,
    Mark
