Abstract In this paper we outline a geometric programming approach to the solid modeling of monuments and the virtual recon- struction of large-scale historical sites. The main concept at the base of this research project is the integration of ad- vanced modelling, simulation, virtual and augmented reality, serious gaming and tracking techniques in one centralized framework, where the security personnel is provided with decision-making tools integrating environment and behavior modeling, knowledge bases and sensor systems. In particu- lar, this paper discusses the current state of the geometric language PLaSM and its current interfacing to scripting and concurrent languages as Python and Erlang. Keywords: VR systems and toolkits (primary key- word); Cultural heritage; Archeology; Security and protec- tion. 1 Introduction TRS (Technology & Research for Security) is a spin-off com- pany of Roma Tre University, with entrepreneurship pro- vided by Theorematica spa and Invent sas. The spinoff has the mission of developing an innovative Platform for Intelli- gent Security of Critical Infrastructures, to assure high levels of awareness and security management of facilities and in- frastructures, like government buildings, historical sites, mu- seums, bridges, railways hubs, airports, etc. TRS is develop- ing ICT systems of a new generation, integrating preexisting security with novel capabilities beyond the present state-of- the-art, and including: behaviour and situation modelling, counter-measure assessment and evaluation, and security personnel training. Advanced modelling and simulation us- ing virtual-reality interfaces is the reference paradigm [2]. The spin-off project is funded by the Italian Ministry of Uni- versity and Research (MiUR). Fouders and shareholders of TRS are: “Roma Tre” Univer- sity, established in 1992 as the third state university of the capital city of Italy, that enters TRS through the CAD Lab of the Dept. of Informatics and Automation and the Mod- elling and Simulation Lab of the Dept. of Studies on Struc- tures. Theorematica spa operates management solutions for
