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 not really into blinking Christmas decoration but this framework makes a lot of sense 😄 thank you for sharing!

@geekmomprojects That's so clever. Presumably you've got it hooked up to a webcam we can't see?

@sarajw yes, exactly

@geekmomprojects @sarajw how do you take note the webcam position and viewing direction? Is it all automatic?

@f4grx @sarajw the mapping code takes care of it all. I just have to set the camera up at a few different angles and run the mapper. No manual measurements required.

@geekmomprojects is the code yours or someone else?

@RueNahcMohr it was written by @themariday , and is far more clever than anything I could do. The first post in the thread links to the code repository.

@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.

@geekmomprojects Oooh I’ve been looking for something like this to make mapping my tree for xlights easier and not have to do it by hand each year!! 💜

@geekmomprojects Wow, that's absolutely fascinating! :rainbow_heart_eyes:

I have not immediate application, as I'll be spending the holidays at my parents' who are still strong believers in sticking burning things (beeswax candles) into highly flammable things (half dry tip of storm damaged tree). What could possibly go wrong? 🙃
