so i am building yet another dome.
this time its aluminum 2v dome like this: 2V Geodesic Dome Calculator » Domerama
most rods will have leds on them.
to make my life easier i wrote an opensCAD script to print me the coordinates of each pixel
you can find the script here:
it consists of an array with joint locations and a function called rod() that takes 3 parameters
(array[x,y,z]) start, (array[x,y,z]) end, (int) pixelnum
it draws a line with pixnum spheres evenly distributed and prints each pixels location on the console so you can use it in the pixelblaze mapper.
i use it for a dome, but you can use it for ANY geometry that can be described in vectors.
of course its CC-0 so have fun and remix.
