View Full Version : Greyscale to 3D Software Needed

03-12-2009, 10:03 PM
I have an idea for a project that would involve taking greyscale images and creating 3D reliefs from them (basically take a headshot of a person, turn it into a greyscale image, and then use that to try and create something that looks like a nickel). If I can find something that would create a 3d file like a .stl or a .iges file that would be terrific.

Cam Bam will create the g-code from a greyscale image to carve a relief.

V-Carve is another product that does the same thing:


3D Grayscale Machining

PhotoVCarve automatically converts a grayscale image into a 3D height map that can then be carved.
The example below shows how the grayscale image for a 3D model can be converted to a 3D height map and machined using a Ball nose cutter.

CamBam Standard is free. :D

Vectric's PhotoVCarve almost gets it right but the tool paths generated are all straight line, sort of makes your images look like a fuzzy TV picture. Cambam looks interesting. I met Andy at the Austin Maker Faire year before last and really liked him. Very dedicated to his project.

Something I will be working on sometime this year is a plugin for CamBam that will generate spiral heightfields of photographic content. A spiral produces a much smoother surface for many 3D shapes because it has less visibly discrete steps than a sequence of parallel lines. It also is harder to discern most types of aliasing that can be a serious problem with an orthogonal array.
