Simulation is a necessary tool if we are to understand better the complexities involved in cardiovascular transport. While some of the phenomena modeled can be described analytically, perusal of the equations alone often doesn't result in full appreciation of the model system. It therefore becomes pertinent to utilize computer graphics in order to enhance simulation of physiologic transport processes. Graphic representation not only facilitates interaction between the investigator and the simulation, it provides a juxtaposition of the model to the real system, as well as a simplification of relationships between various features of the model.Increased mathematical sophistication required in the investigation of cardiovascular transport phenomena often makes traditional graphic representation cumbersome. Therefore several different types of graphics have been utilized, including 2-, 3-, and 4-dimensional displays. The methods and algorithms for these displays have been generalized to make them easy to use over a broad spectrum of applications. In some cases we have generated motion pictures of sequential model solutions which have increased and accelerated model comprehension, as well as been valuable for teaching purposes.
如果我们想要更好地理解心血管运输中涉及的复杂性，模拟是一种必要的工具。虽然一些建模的现象可以通过分析来描述，但仅阅读方程往往无法充分理解模型系统。因此，利用计算机图形学来增强生理运输过程的模拟就变得很有必要。图形表示不仅便于研究者与模拟之间的交互，还能将模型与实际系统并列展示，同时简化模型各种特征之间的关系。在心血管运输现象研究中所需的数学复杂度增加，常常使传统图形表示变得繁琐。因此，人们采用了几种不同类型的图形，包括二维、三维和四维显示。这些显示的方法和算法已经得到了推广，以便在广泛的应用中易于使用。在某些情况下，我们生成了连续模型解的动态图片，这些图片增强并加速了对模型的理解，并且在教学目的方面也很有价值。
