<![CDATA[Measure Color but in several instances?]]>Hey, can someone help me with this one? I'm pretty sure this is possible and maybe even easy, but this has stumped me for a bit.

Let's say I have a simple video feed of a thunderstorm but I would like to capture the color of the video to pass this info to DMX and to lighting fixtures. This I have actually accomplished, but is there a way to somehow map this data for a set of, say, 10 fixtures? As in the video is split in ten strips and each of them send the "measure color' data to one fixture? My idea is to spread a number of fixtures on the floor and have the light "simulate" the visual effect of the thunderstorm.

If you want to control 10 fixtures, you need 10 Measure Colour Actors, each set to a different portion of the incoming video feed. Each one will give an average colour for that particular area of the image.

The RGB values can be sent on different channels of DMX to your lighting fixtures, or converted to HSB and sent, if your lights prefer this mode.

There is a tutorial for using LED strips if you look at the tutorial part of the website and then under interface/sensors. It is a tutorial for mapping video to pixel strips through the Artnet add-on modules. It works well once you get your head around the workflow.

You might want to have a look at the Color Matrix Send actor. It pairs with Matrix Value Receive actors to map video to lighting through ArtNet Send addon.

Best wishes
