Formal graph languages of shape
Patrick A. Fitzhorn · Artificial intelligence for engineering design analysis and manufacturing · 1990
The study of languages of shape is rich and interesting. One can develop formal grammars whose languages are non-realizable shape (nonsense objects), as well as grammars whose languages are classes of realizable shape. This paper develops several graph-based multi-dimensional languages that are complete in the physical solids. Thus, realizable shape is a language.
