Finally got around to Pixel mapping my friend's Pixelblaze-controlled Christmas tree using @themariday 's video pixel mapping tool (https://github.com/TheMariday/marimapper), and it was fantastic! I could never have mapped the 600 LEDs on this tree without it.

Here's a short clip of the mapping in progress. The mapping code locates individual pixels by lighting them one at a time to create a 2D map then combines several 2D maps taken from different angles into the final 3D map.

@geekmomprojects So once you have the LEDs mapped out you can control them dimensionaly? Like lighting flowing from the trunk out to the tips of the branches?

@virtualbri yes, the Pixelblaze controller combines the map with 3D patterns for a great effect. Here's a different 3D pattern running:

@f4grx @geekmomprojects @virtualbri

Do you take viewer submitted Python animations?

@geekmomprojects @virtualbri how do you create the map? Is it simply a case of being very specific about how you drape your chain of lights around the tree?

@Workshopshed @virtualbri no, my friend put the lights on the tree in a pretty arbitrary fashion, and I used video-based mapping code that works with the controller (see the first post in this thread for details) to determine their positions afterwards.
