<p>Large point clouds from radars and these-dimensional scanners are commonly used in Archaeology. However, in most cases these models cannot be properly integrated and used in software such as heritage management due to its large size. Therefore, some tools to make this management easier and optimize the processing are needed. In this work, we propone the integration between OpenVDB and GRASS in a C++ module to combine the widen functionality of GRASS GIS with the 3D models management efficiency of OpenVDB. Specifically, this application is used to combine the topographic information of a city with the 3D models of the most significant buildings. This application can be useful for both current cities as well as for virtual reconstruction of existing villages in the olden days and currently disappeared. </p>

<p>Thanks to the development of the new technologies, virtual museums have incorporated new contents that make the transmission of the knowledge easier. These new elements should be included considering not only technical features but also usability and simplicity requirements for end users. In this paper, we describe the evolution of the main technologies utilized in the creation of virtual Museums, specifically those which generate 3D content. We also describe how to include these new contents in order to obtain a successful result. Finally, we compare virtual Museums with another traditional ways of transmitting knowledge such as, real museums, books, and magazines.</p>
