Video to light - Traditional Fixtures

DCMP

Hi all!

I'm looking to use Isadora to translate video to intensities of a matrix of traditional light fixtures. Im using the Lanbox as my DMX controller/interface, and will most likely use a wifi router that will be hard wired to one computer running the lanbox software, as well as a second computer running Izzy. So I will use the Artnet send actor. Does anyone have an example patch of how this can be achieved in Izzy?

Thanks and all the best!

@DusX Any tips?

Lanbox as my DMX

I don't have a Lanbox, so I can't comment directly on this. However, collecting color data from video is pretty easy, and I do this all the time, for many self running effects. "Measure Color" is your friend here. It allows you to look at a region of the video (left half, right half, maybe break it into row and columns) and get a RGB value for the region. So if you are controlling LED lighting you can set it to the same (or related) color. You can derive the brightness from the RGB values (use BT.709 formula) as well, if you just want to control the one value per output.

Hi,

I have some LanBox LCX Isadora resources that can be shared:

Izzy DMX_LanBox

records DMX states for RGBWAU light instruments and sends to LanBox Channels. You could combine this with a pixel map technique such as demonstrated in the example following:

Pixel map made by gertjan biasino would be useful. @GertjanB if I may be so bold to re-share the fine work of another Isadorable!

Best Wishes

I know I can't exactly be considered unbiased, but it's hard not to point out in situations like this how much I really love this community.

This is exactly why, when people contact me directly with questions, after I do my best to help (if I can), I also always add that they should go ask their question on the forum too. I may have ten years of high-level experience with this software but that's just a drop in the bucket when compared to the combined knowledge of the community as a whole.

Y'all are awesome <3
