Well, I have set out to search for the holly grail as it would seem... My aim is to turn our wedding photo's to a 3D Surface file for machining.
I thought of starting simple (Bmp/jpeg of objects) and moving to Complex (tif /gif portrates)
so the aim:
Convert BMP's to grey scale
Modify the number of colours to give the correct pospective
Asign a value or weight to the shade of grey
create a polygon mesh to render
ability to add curves to corrctly define shape ? (maybe an option)
add a surface to mesh
increase resolution
save as DXF or other CNC format.
when it came to portrates I had thought of applying a standard Mesh to indicate the main features of a face and give the colours / shades points of reference with respect to the rest of the facial features
anythoughts ideas or code would be great as I have little experience but willing to learn
