Romulus isboundary representation (b-rep)solid modeling software, released first in 1978 by Ian Braid, Charles Lang, Alan Grayer, and theShape Data team inCambridge, England.[1] It was the first commercialsolid modeling kernel designed for straightforward integration intocomputer-aided design (CAD) software. Romulus incorporated the CAM-I AIS[2] (Computer Aided Manufacturers International'sApplication Interface Specification) and was the only solid modeler (other than its successorsParasolid andACIS) ever to offer a third-party standard application programming interface (API) to facilitate high-level integration into a host CAD software program. Romulus was quickly licensed bySiemens,Hewlett-Packard (HP), and several other CAD software vendors.
