Could Pixelmad control up to 60 Universes of DMX?
I just got the specs for a big LED installation in autumn 2005 on my desk.
I am working quite close with the developer of the LED panels and we came to the discussion how to control such a big LED setup.
I put pixelmad in the game not really knowing if it could handle an installation of that size (given a maximum of 40 Universes on the pixelmad-website) - but anyway I would not know any other control application to handle this...
Requirements for control software would be approx. 60 Universes of DMX and a pixel array of at least 200 x 200.
Question: Would pixelmad be the right software to control this? And what would be the hardware requirements for the mac running pixelmad...
Or would it help to have an array of pixelmad servers all getting the same commands but controlling other parts of the LED matrix... - if so what about syncing...
In my personal opinion there is no other way to treat an installation big as this other than as video data... Talking about preproduction in Aftereffects rather than programming content on site...
You could not come close to the same results using generic matrix effects - even given you have a console capable of controlling 60 Universes...
As said above all of this is in an early projecting state - this is just a technology check to see what is possible...

Fixture count and specs...
It will be an area of around 400 square meters lit by LED tiles 20 cm by 20 cm.
That makes 25 fixture per square meter and a total of 10000 fixtures - if you consider each tiles as a single RGB fixture - would be 2000 fixtures of you consider a row of five tiles as a fixture. Anyway it results in 30,000 channels of DMX that would be about 60 universes...
The pixel array size is still important as it will not be compact like a square but the fixture will be more distributed... My guess right now is an image size of 200 x 200 would be fine...
For now I will pass on the info that 60 universes are possible - that sure is a winning point :-)
I will get back to you as soon as I know some more...
Thanks so far,
Olli
Tested 240 Universes Pixelmapping...
Yesterday I tested a 240 universe Pixelmad patch. (1600 Fixtures)
For starters I just tested on my MacBook Pro - and it did not run stable...
Application freezes after a few seconds - even faster if you have the Pixelmixes window open.
Seems to be to too much work for the MBP - I will try it on my 8xCore as soon as possible.
