摘要：Simulating the scenery of climate environment can consumedly enhance the reality of 3D GIS, which has been widely used in computer games, movies and visual simulation system, but until now there hasn�t been one effective solution to realize simulating climate environment when cruising the terrain in 3D GIS. In this paper, a simple method of climate environment emulating in transparent form based on DirectX is promoted. The basic concept of this method is imitating snowing by applying particle system, then updating the form using the graphics rendered and vitrifying the form utilizing Windows API. The result of the simulation shows that the method in this paper is simple to implement and can satisfy the requirement of real-time and reality.
