摘要:

在满足虚拟游戏实时性要求的前提下,绘制具有一定视觉真实感的草地,以增强游戏场景的真实感.将草地抽象成一块均匀、连续的透明体,提出一种简化层状算法,利用图形处理器(GPU)支持功能,计算穿过草丛的光的能量衰减,高效地模拟草的自阴影效果,并通过加入Perlin噪声进一步增加草地阴影杂乱交错的效果.结果表明,该方法能以极小的性能代价绘制草地阴影,实现具有一定真实感的大面积草地的实时绘制.

Abstract:

A grassland rendering method for augmenting the realistic effects of visual scenes in 3D games was presented based on the prerequisite of real-time requirement of visual games.It abstracted the grassland as a uniform and continuous transparent body,and a simplified layered rendering algorithm was proposed.Taking the powerful supporting function of the graphic processing units,the self-shadow effect of the grass was simulated efficiently by calculating the optical energy attenuation which passing through the grass.Moreover,Perlin noise were multiplied to represented the disperse shadow resulting from interlaced grass,which augmented the render effects greatly.Results show that the method renders the grass shadow at very low costs,and generates large-scale grassland with realistic effects at real-time.
