Idea description

Many CAM applications can take a grey scale image and interpolate the color to a height map. This is useful for producing lithophanes. LinuxCNC has a image to gcode capability. It would be nice if FreeCAD could generate this information from an image plane attached to a base object.

Anything else?

I too have been trying to do this, without success. I can create a solid from a lithophane, using the Part workbench, but then I can't integrate it into a model for milling. I'm interested in creating plaques for house signs, which incorporate the name of the house together with a carved image. Is anyone else interested in doing this sort of thing?
