I've seen some of the 3D (not 2.5D) laser engraving artwork and I'd like to try my hand at it.
But I can't seem to find much written on the subject, and not quite sure the methods used, software, etc. If anyone has any specific info, links, etc. I'd appreciate.
I realize it's 256 shades of grey to give varying depth. But are they starting with something like Blender/Bryce and going from there? Is it something more 3D CAD? Something else?
The closest I've found is this:

Unfortunately, it doesn't show the original image/artwork that was used to create the greyscale one.
