摘要
Abstract
Fog effect can enhance the realism and distance of scene. Linear, exponential and exponential-squared fog parameters are enumerated in Direct3D, and they make the real-time rendering rapid and convenient, however, the various transformations of fog are limited by the only three parameters. Fog factor is the key to define the formula of parameters, and vertex shader has the ability to render vertex separately. This paper discusses a way to reconstruct the formula of fog factor by combination of the features above, gives an example, which can implement the fog effect according to the altitude of scene, the distance between observer and scene and the density of fog. Experimental results show that the restriction of original parameters can be improved in this way, and fog effect in reality can be imitated freely.关键词
