项目摘要

The objectives of this research effort are 1) to extend to motion and surfacedeformation the investigator's prior research in perceptually basedvisualization of texture, and 2) to develop a practical system based on thisapproach that will handle actual motion and deformation visualizationproblems. The method is based on the method the investigator has already employed withsuccess for texture visualization. The method will proceed in a number ofstages. First the computational paradigm used in the investigator's texturesynthesis system will be adapted to surface deformation. Then an initial setof texture attributes that are potentially of perceptual significance will bedefined. This set will form the foundation for a library of applicativefunctions that will be implemented. Users will compose these functions tocreate visual syntheses of specific types of naturally occurring motion andsurface deformation. Those functions discovered to be useful for this processwill form the basis of a perceptual attribute taxonomy. This taxonomy canthen be used to form a systematic parameterized approach to realisticvisualization of surface deformation. The new contributions will be a taxonomy of perceptually significant motionand deformation operations, and a working system of perceptually based userinterface for visualizing motion and surface deformation. A key result willbe that the user of such an interface will be able to specify and controlhighly realistic visual simulations without having to be overly concerned withdetails at lower levels.

本研究工作的目标是：1)将研究者先前在基于感知的纹理可视化方面的研究扩展到运动和表面变形；2)基于这种方法开发一个实用的系统，以处理实际的运动和变形可视化问题。该方法是基于研究者已经成功使用的纹理可视化方法。该方法将分几个阶段进行。首先，研究者的纹理合成系统中使用的计算范式将适应表面变形。然后定义一组可能具有感知意义的初始纹理属性。这个集合将构成将要实现的应用程序函数库的基础。用户将组合这些功能来创建特定类型的自然运动和表面变形的视觉合成。那些被发现对这个过程有用的功能将构成感知属性分类法的基础。这种分类可以用来形成一个系统的参数化方法，以实现表面变形的逼真可视化。新的贡献将是感知意义上的运动和变形操作的分类，以及用于可视化运动和表面变形的基于感知的用户界面的工作系统。一个关键的结果将是，这样一个界面的用户将能够指定和控制高度逼真的视觉模拟，而不必过分关注细节在较低的水平。
