    While I realize that Estlcam is very nice for generating toolpaths for designs that have been rendered in a CAD package or a vector drawing tool such as Sketchup or Inkscape, I’m wondering if there is anything out there that will help to generate a 3D relief image from a photograph, for example.  Estlcam apparently can handle that type of file as well.

    For example, in 3D printing you can take a photo and generate a “lithophane” that is meant to be viewed in transmission.  Is that just a sort of “negative” of a appropriate image for 3D carving?  It’s not clear to me if this is the case.

    Also, given that we have Estlcam, we don’t really need a complete CAM package, such as “Deskproto”, which can probably do the task, but has a signficant cost and seems to duplicate Estlcam.

    And, yes, I realize that Fusion360 can generate 3D relief images, as can Sketchup with proper extensions.  But, going from photo to 3d is still a different issue, I think, particularly in the world of “cheapware”…

    Estlcam has image tools, or you can generate a 3D printer stl of your lithopane and set up the mill path with estlcam.

    Nothing can create an accurate 3d model from a single image.  Lithophanes just interpolate black=thick white=thin, then ramps between for grayscale.

    For the lithophanes don’t you end up with an STL, that we could end up milling?

    Never mind I see what you are saying, it will not look right milled.
