| Abstract: | Anyone who has attempted to do 3D GIS visualization has ultimately drawn the comparison with 3D games and wondered “Why can’t I make my scene look like that”. There are several reasons for this, but a primary reason is that GIS has never, until recently, leveraged the Graphics Processing Unit, or GPU. By taking advantage of the GPU, GIS visualization can experience the same exponential increases in performance and visual quality that we have seen in games for the last decade. This presentation will explain what the GPU is and how GIS and the Geoweb will benefit from it. Using the GPU, it is possible to create immersive virtual landscapes that include up to millions of 3D objects, interactive lights, and informative thematic overlays, with no need for complicated workflows or cache management. We will introduce a new 3D geospatial visualization application called Geoweb3d Desktop, which provides advanced GPU-based rendering tailored specifically for GIS. Large-scale, gaming-quality 3D urban or natural scenes can now be generated in minutes, through direct integration with ArcGIS and the Geoweb. A demonstration will follow showing how a large, high-fidelity scene can be constructed quickly and on the fly, directly from unaltered geospatial data. |
