Romulus (modelling kernel)

Romulus is boundary representation solid modeling software, released first in 1978 by Ian Braid, Charles Lang, Alan Grayer, and the Shape Data team in Cambridge, England. It was the first commercial solid modeling kernel designed for straightforward integration into computer-aided design software. Romulus incorporated the CAM-I AIS and was the only solid modeler ever to offer a third-party standard application programming interface to facilitate high-level integration into a host CAD software program. Romulus was quickly licensed by Siemens, Hewlett-Packard, and several other CAD software vendors.
