Cartografia Histórica em 3D e Realidade Virtual: uma metodologia de baixo custo

The purpose of this article is to develop a methodological workflow, using low-cost solutions to carry out parametric three-dimensional modeling of buildings and objects belonging to historical-cultural and material heritage. In the context of Historical Cartography, the objective of this work is to promote the dissemination and preservation of Historical Heritage through the use of Virtual Reality, thus providing an interactive, immersive and dynamic approach. As an example, a military building was used, which was built in the 19th century. This building was modeled in 3D based on its original topographic plant and implemented in Virtual Reality for visualization. The applied methodology used cartographic data obtained from the original topographic plant of the building and current scenario photographs, to respectively generate the parametric three-dimensional model and its texturing, in order to resemble the original structure. From the 3D model of the building, a Virtual Reality application was created for the Android system, using the Unity graphics engine and programming tools from the Google API console. The obtained results were adapted for visualization and navigation with the aid of a low-cost virtual reality glasses solution.
