Picture Relief Map

Here is a picture relief map, usually called a lithopane: aer_1948.stl.

Lithopanes are inverse relief maps and the fortran program used to make relief maps, see thing:110173, was easily modified to make lithopanes. The program takes a grayscale negative in raw format and outputs an openSCAD program. When the openSCAD program is executed a lithopane is produced.

The source code and input file are included.

Makerbot has a lithopane tool that turns any photograph into a lithopane - see t
