The problem is the photo shows light/dark as the camera sees it, and doesn’t map that to height/depth.
The concept you need to look up is “photogrammetry”:
Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.
The term photogrammetry was coined by the Prussian architect Albrecht Meydenbauer, which appeared in his 1867 article "Die Photometrographie."
There are many variants of photogrammetry. One example is the extraction of three-d...
As-is, the photo can be used for a halftone:
This was announced/demoed in a limited way a while back — had occasion to reference it in a support ticket recently, so here’s the text from that:
We have a halftone generator which will accept black and white images, so you will need to convert any image into a black and white picture. That is the only type of picture the generator will accept. Help file: https://cutrocket.com/halftonehelp.php
Or, you could do a lithophane:
A lithophane is a thin plaque of translucent material, normally porcelain, which has been moulded to varying thickness, such that when lit from behind the different thicknesses show as different shades, forming an image. Only when lit from behind does the image display properly. They were invented in the 19th century and became very popular, typically for lampshades, nightlights, or to be hung on windows. They could also be given stands, to be placed in front of a light source. The longe The i...
If you want a 3D model and you can’t get a 3D rendering using photogrammetry you will need to draw the outline of each significant height/depth change and do it as a 3D model element in some suitable program, or create a complete 3D model.
