Guys anyone know an opensource solution for doing this?

I’d say the logic behind making litho panels would be a good place to start as that converts contrast to depth/height map then it would be off to a Cam software to do a 3d profiling path with a heavy offset between passes… I don’t doubt all the tools need are in the open source area right now but i haven’t seen them together. I would love to see someone with more skills than my self put something together for this.
Look at Makeangelo . I’m willing to bet that code could be modified to achieve this.
GIMP (GNU Image manipulation program) has a newsprint filter that can do dot and line halftones. I’ve been experimenting with some custom software for generating line images, but using Aspire for the CAM processing.
Here’s what I would consider using. (DXF Halftone)
I’ve downloaded the software but haven’t gotten around to using it yet.
Inkscape is another free one that filters images and output dxf
I’ve played around with this software but never gone as far as to mill it on my CNC.

+Peter van der Walt I think tha would result in narrow dark stripes or wide light stripes or somewhere inbetween and not get you an actual difference in brightness for an area. Z offset plus intensity on the otherhand would probably work. Note that I am assuming you mean for laser work. For CNC work, a Z offset plus some translucent dark stuff would work.
+Peter van der Walt fill the groove with stain and you could do it V bit or any other bit. Just substitute Z for S and do not use variable speed control. Solid black paint filling a V bit cut and then sanding the paint off the top surface will also work.
