Layout requirements of a 3D molecular editor specified with DEViL3D

Abstract

Our generator system DEViL3D generates 3D visual language implementations with a specialized structure editor as its front-end. An important example for 3D languages are the “ball-and-stick” models of molecules. The layout of molecules is particularly important as it has to match chemical rules. This showpiece shows, how language designers who want to specify a molecular editor with DEViL3D are able to specify such layout rules by using the concept of spherical coordinates.
