Real Time Modeling and Rendering of 3D Tree

摘要

In recent years, the virtual-reality simulation technology has developed so fast which has been widely used in military and people's daily lives, etc. As the essential element of the three-dimensional scene, modeling of trees becomes increasingly important. There are many methods for 3D modeling trees such as 3DMAX modeling, the bulletin board technology, the crossing panel and the LOD technology. However, these methods are not so effective either for the bad real-time performance caused by the large quantity of data or the unsatisfactory 3D effect. Therefore, this paper is aiming at proposing a 3D tree modeling method which was based on the combination of Fractal and Non-rectangular raster image technology.
