Abstract :
This paper reports on a visual simulation system that supports GIS-based realistic modeling and real-time rendering of forest scenes. Geometric models of trees are automatically generated according to inventory database and pre-designed template models. A combined image and geometry representation method for 3D tree model is given with a specific level of detail algorithm for ensuring real-time frame rates. We have tested and evaluated the system in applications of walkthrough simulation and forest fire visualization.
