Computer graphics has made great advances in producing realism and detail in synthetic scenes, yet these techniques have not been applied to scientific visualization. A realistic-looking 3D scene is immediately and viscerally apprehended, which promotes understanding of its contents. Fidelity of shading is important to a person viewing an already-familiar architectural environment. Such fidelity is even more important for a person viewing the complicated and unfamiliar geometry of isosurfaces and field lines that reveal the features in a dataset resulting from computational simulation or from physical measurement. This project will develop global illumination techniques for isosurfaces and field lines in 3D data, with applications to medical data and engineering data.

计算机图形学在合成场景中产生真实感和细节方面取得了巨大进步，但这些技术尚未应用于科学可视化。一个逼真的3D场景是立即和发自内心地理解，这促进了对其内容的理解。对于一个人来说，观察一个熟悉的建筑环境，阴影的保真度是很重要的。这种保真度对于观察复杂和不熟悉的几何形状的等值面和场线的人来说更为重要，这些几何形状和场线揭示了计算模拟或物理测量产生的数据集中的特征。该项目将开发3D数据中等值面和场线的全局照明技术，并应用于医疗数据和工程数据。
