人体皮肤真实感实时渲染研究

人体皮肤是一种高度散射的半透明材质，与光线之间的交互过程很难建模和模拟，因此皮肤的真实感实时渲染比较困难。从基于模糊化处理的渲染、基于纹理空间的渲染和基于屏幕空间的渲染等三方面，对皮肤真实感实时渲染进行综述，详细分析了每种方法实现的思路和原理，方法之间的改进和差异，对各种方法的优缺点和适用范围作了总结和比较等，最后给出了将来研究的方向。

Research for Realistic Real- time Rendering of Human Skin

Human skin is a highly scattering translucent material, and the interaction between skin and light is difficult to be modeled and simulated, so realistic real - time rendering for human skin is very challenging. This paper discusses three aspects such as rendering using blur processing, rendering in texture space and rendering in screen space, and gives a sum- mary of realistic real - time skin rendering. Each process of rendering is analyzed in details, and its improvement and difference is discussed. Also, the paper describes the advantages and disadvantages of various methods, and compares dif- ferent application scope. At last, the paper gives the research direction in the future.
