I think I would be concerned with the word "Cheap" sometimes you get what you pay for. Look at the low bid on the space shuttle challenger O-rings.

Dear Jeffrey I am also in Jewellery industry and we have some applications like producing stamping moulds from a grayscale bitmap.


We are using ArtCAM, Cimagraphy, Quickshape, Unigraphics and Mechanical Desktop for these applications which fits to application.


Yes you are right that some of the details are lost during the transformation of the datas but with some small modifications you can achieve good results. We are nowadays making the ancient Greek Gods as pendants.


This software that you have mentioned using CAT scans or MRI is a software of Materialise. I have not been able to try it yet but I saw some very succesfull sterolitography models of human being organs.

I gave this quite a bit of thought several years ago in order to create 3D medallions of baby portraits (I'm a jewelry manufacturer). I even did several tests using various techniques and got some decent results, but they took a LOT of work to produce so I gave up on it as too costly.


Heightfield bitmaps don't work very well unless they incorporate intelligent depth algorthms based on 3D facial features, unless of course you desire a highly foreshortened and flattened 3D image (like that on a coin but not nearly as nice). I don't think the software is written yet to do what you want unless you want to spend a bunch of money to adapt existing facial reconstruction software, and I'm way out of my league even mentioning something like that! (I think that kind of software uses point clouds from CAT scans or MRI)

Dear Dan,


For this kind of application you can use may be the software Artcam. Artcam can make 180 Degree models maybe you can split your digititized photo in 4 pieces and then after modeling you cam export them out as an .stl file and join them in any other software.


There are many other softwares like ArtCAM those can make models from grayscale .bmp files.

Does anyone know of a process or software that would take a digital image (photo) and somehow result in a 3D solids / model? The application is based around a request to take a digital picture of a human head and create a 3d model.


Thanks for your help.
