I love these projects. I did a related project where I created a single, solid object that has 4 different silhouettes/shadows from 4 different angles in the same plane. Using more view angles than dimensions makes the problem much more complex. I suspect it is not possible to do this purely programmatically so I did it by hand had to smudge the letters to get everything to work out.

Thanks for sharing. Yes, what we found is that multiple input images often are not consistent with each other (i.e., no physical volume that can satisfy the constraints from all the views). We thus start with a set of consistent voxels and connect them so that the projections are as similar to the inputs as possible.

ZKM in Karlsruhe, Germany has an exhibition called Open Codes, where they have used a single solid object to generate all letters in the alphabet using projections.

There supposed to be a spiral encoded in the first chapter of genesis. And the spiral itself encodes the alphabet the encoding of the spiral is written in. Very quine like ability. I am not familiar with any other alphabet achieving this. http://meru.org/letteressays/letterindex.html

Here he breaks down the encoding. It's basically: the first verse of genesis + the order of the alphabet = a structure. https://www.youtube.com/watch?v=OJGW2UANWRE
