Trying to think of a way to map an image onto a grid of layers or objects, like the QC example, “Image Texturing Properties Grid.qtz” (which uses javascript and an iterator). Any ideas? Can the art-net stuff do this?

Not sure if I understand completely what you want to do, but it sounds like you could just make a grid list, then use the Process List node along with the Sample Colors from Image node to turn it into a color list. The Art-Net nodes can output the color data to physical (or visualized) LED strips and the likes.

That’s something to start with, thanks, Magneson!
I’m using the @smokris (<–should be smokris) technique from https://community.vuo.org/t/-/5078 to make a grid, and Crop Image + Sample Color from Image to get image colors for the grid. So far only very “low res” matrices can come close to keeping up with a video. Is there any way to up the performance?

Why do you crop the image? I think you should also put a hold node between the movie frame and the crop/sample color node triggered by the Process Item output port.
Yep, removing the crop is an immediate performance improvement. Not sure why I thought I needed that… Thanks, Magneson!
Alastair, build a game of life in Vuo!

Very interested in this direction with the LED matrix! We are currently trying to figure out the serial data stream to address WS2812B LEDs and would like to build and test pixel arrays in vuo. Nice work @jersmi
too many other things I want to build in Vuo first when I get a chance.
I was just considering the problem this week when looking at a representation of Conway’s Game of Life on Wikipedia. Some of Kineme forum members used to fret about not being able to do this sort of thing in realtime in QC back in the dayz. Splitting an image into a colour value matrix to apply to objects would be a lot of fun.
Thanks for posting your composition @jersmi
