计算机图形学中逼真渲染的视觉保真度从根本上取决于我们如何对到达眼睛的光和物质之间相互作用产生的物体外观进行建模。本文综述了人体活体组织外观模型的研究进展。在计算机图形学已经研究的许多种类的天然材料中，活体人体组织，如血液和皮肤，最近受到图形学研究的越来越多的关注。关于这个主题已经有了一个初步的但实质性的文献，但我们也缺乏一个结构化的综述。我们介绍了一个分类的方法使用四种类型的人体组织作为分类器。我们展示了使用物理学和生物学的第一性原理作为建立模型的基础知识的解决方案的增长趋势。这些生物物理方法提供的视觉结果的有机质量主要取决于生物物理成分与光相互作用的光学特性。除了图像制作，这些模型还可以用于预测模拟，在许多其他领域具有潜在的影响。
The visual fidelity of realistic renderings in Computer Graphics depends fundamentally upon how we model the appearance of objects resulting from the interaction between light and matter reaching the eye. In this paper, we survey the research addressing appearance modelling of living human tissue. Among the many classes of natural materials already researched in Computer Graphics, living human tissues such as blood and skin have recently seen an increase in attention from graphics research. There is already an incipient but substantial body of literature on this topic, but we also lack a structured review as presented here. We introduce a classification for the approaches using the four types of human tissues as classifiers. We show a growing trend of solutions that use first principles from Physics and Biology as fundamental knowledge upon which the models are built. The organic quality of visual results provided by theseBiophysicalapproaches is mainly determined by the optical properties of biophysical components interacting with light. Beyond just picture making, these models can be used in predictive simulations, with the potential for impact in many other areas.
