3d Solid Representation and Visualization for Large Heterogeneous Sites with Urban and Rural Heritage - a Case Study
نویسندگان
چکیده
This article introduces usage of 3D solid modeling methods in order to represent and visualize highly complex environments such as large heterogeneous sites integrating urban and rural heritage content. The theoretical bases of a new simulation system implementing this approach will then be detailed. The article will present a case study concerning urban and rural sites 3D solid modeling for the state of Vermont. Finally, it will discuss the various challenges to face in order to extend this use case to other states. This approach virtually enables interoperability between the various sources of legacy data, federating them in a 3D Solid dataset representation, designed for large heterogeneous sites. The first part of the article focuses on theoretical problems: multi-model architecture problems, legacy digital representation and mathematical surface models applied to architecture. It then introduces the proposed approach in terms of geometric description and graphical rendering principles. Such theoretical bases allow defining new generation paradigms for the creation, management and deployment of large 3D Solid Datasets. The second part of the article presents the Virtual Vermont project, which implements the proposed approach, integrating within the same simulation environment various data sources, including heritage, GIS, infrastructure and enables a wide number of applications.

The center of Amman (Downtown) is one of the most marvelous sites in Jordan as it represents a wide range of heritage through time and space. However, the Downtown suffers from severe disorders in terms of negative urban development due to the cross cutting cultures between the past and present. Despite of its historical and cultural richness, several factors affected the architectural uniformi...

4d Reconstruction and Visualization of Cultural Heritage: Analyzing Our Legacy through Time
Temporal analyses and multi-temporal 3D reconstruction are fundamental for the preservation and maintenance of all forms of Cultural Heritage (CH) and are the basis for decisions related to interventions and promotion. Introducing the fourth dimension of time into three-dimensional geometric modelling of real data allows the creation of a multi-temporal representation of a site. In this way, sc...
متن کاملUsing Benthic Diatoms as a Bioindicator to Assess Rural-urban River Conditions in Tropical Area: A Case Study in the Sai Gon River, Vietnam
The changes in diatom assemblages along an urban-to-rural gradient were characterized to assess the ecological status of the Sai Gon River, Vietnam. Diatoms and physico-chemical variables were measured at 10 stations during dry and rainy season. One-way ANOVA showed that diatom metrics and physicochemical variables were significantly different (p < 0.05) between the upper course sites and both ...
