The document proposes a method for dynamically mapping raster data onto 3D geovirtual environments using projective texture mapping. This allows for real-time visualization of large, time-critical geospatial datasets. By partially decoupling geometry and appearance, the method enables dynamic multi-texture mapping, color transfer functions, and rapid configuration of different mapping options. The approach extends graphics APIs like OpenGL to perform per-fragment dynamic texturing via shader programs. This achieves interactive framerates even with multiple texture mappings. The method is demonstrated through examples including hierarchical data layer combination, object highlighting, and interactive digital map design.
