    摘要:

    基于毛发的多层纹理表达方法,提出一种毛发实时绘制方法.该方法充分利用图形处理器的绘制功能,不仅能对毛发进行高精度快速的光照计算,而且能够高效地模拟毛发间的自阴影效果以及物体其他部分在毛发上遮挡形成的软影现象,以增强毛发的真实感效果.实验结果表明,该方法能够实时处理中等规模的模型,这对于毛发物体在电影、游戏和虚拟现实等领域的应用具有重要的价值.

    Abstract:

    Based on the multi-layer textures approach, a new method of rendering real-time fur is proposed. The method takes full advantage of the new features of current Graphic Processing Units to compute the lighting of fur precisely and fast. More importantly, the self-shadow effect of fur and the soft shadow phenomenon over fur are simulated successfully, which enhances the rendering effects greatly. Experiments show that the method can deal with moderate models in real-time, which is very valuable for the applications of fur in many fields, such as cinema, video game and virtual reality etc.
