Preserving heritage sites of Dhaka City using 3D modeling and virtual reality technology

Abstract

This thesis presents a model that is aimed at preserving heritage sites of Dhaka by implementing 3D modeling and Virtual Reality technologies. The proposed model consists of reconstructed 3D models of historical establishments, a Virtual Reality application and a digital archive of the aforementioned 3D models. To implement the proposed model, three dimensional reconstructions of few prominent heritage sites are created by using 3ds Max. Then the 3D models are implemented in a VR environment so that users can explore the heritage sites and finally to preserve the 3D models, a digital archive has been created to store the 3D renderings of the heritage sites. The website shows 3D animation of the heritage sites of Dhaka such as the historic buildings of Lalbagh Fort, which include The Tomb of Pori Bibi, The Diwan-i-Aam and the Mosque, the structure of Shahid Minar and the model of the Greek Memorial. The Android application directs the user to view the three buildings of Lalbagh Fort in a VR environment. The experimental results demonstrate that the model is successful in utilizing 3D modeling techniques and Virtual Reality applications that can help to conserve the heritage sites of Dhaka
