dc.description.resumo | This work presents a tool to recreate hydrographic networks for 3D virtual scenarios using Geographic Information System (GIS) data. A vector description of the hydrography and a raster description of the terrain are used as input. The vector data is subdivided using a spatial hashing technique and the river data structure is modeled as a graph from where the water surface mesh is generated. The geometry is sent to GPU from where footprint textures and associated shaders are employed to allow terrain shape modi cation and texture mapping, producing various river feature elements. The solution is primarily targeted for simulation systems, but the concepts can be applied on 3D games or virtual environments in general. Results show a simple yet e cient process that provides quality visuals. | por |
