摘　　要：为了在虚拟人体经络系统中模拟循经感传现象,提出了一种基于GPU的纹理混合技术,通过对三张不同色的纹理贴图进行采样,在GPU的像素着色器中根据混合公式合成最终的纹理,实现了循经感传动态模拟效果。程序设计结果表明:在不同的模拟参数下,系统都能够实时逼真地重现循经感传过程。因此采用多纹理混合技术来模拟感传是一个合理有效的解决方案。For simulating the sensation conduction along meridian （SCM） in virtual human＇ s meridians and collaterals system, in this paper it proposes a method based on GPU multiple texture technology. This method samples images from three different colour texture mappings, and synthesizes final texture based on mixture formula in pixeI shader of GPU, by which the SCM simulation effect is implemented. The programming results show that this design can reconstruct SCM reality real-timely with different parameters. This means that it is a rational and effective solution to use multiple texture technology in the simulation of the SCM.
