You need a depth map to get a true to life 3D engraving, but you can get interesting results using a regular grey scale images as well. Just keep in mind that the darker the color, the deeper it burns. These are the 3D posts I have bookmarked.

I have to re-visit the depth map file because both eyes should have been completely clear and the stitching over the mouth should be clear as well but that detail is so tiny it just got washed out in the laser process. Think I might try this again without defocusing at all so those details dont get burned out.

A little ways back I told @Jules I would do some Depth Map tutorials for the repository, and had started some basics. Then @dan released the Glowforge logo usage guidelines, so I decided to start fresh using the logo.
This is more of a conceptual approach than a specific How-To, because of the various methods and software to go about creating the artwork. Whether you’re using vector software like Illustrator, Inkscape, Affinity Designer or CorelDraw, or raster image editing software like Photos…
Sarbarmultimedia and @m_raynsford have some interesting tests at variable depth engraving. I won’t call it 3D because these are far from finished examples of what will be possible with 3D engraving enabled.
I’m curious, especially with @takitus chipping away at this feature on the Glowforge. I thought I would see how gradients in Inkscape worked, exported as a PNG with no processing. Just brought in to the UI, rescaled smaller and printed.
