ILLUSTRATIVE DEFORMATIONProf. D. Silver, Dept. of Electrical and Computer Engineering, Rutgers, The State University of New JerseyResearch Abstract:3D data (from 3D imaging, simulations, sensing) is prevalent in many scientific fields such as medicine, biology, engineering, psychology, security & screening, and archeology. However, the effective exploration of 3D data is still a challenging task. Especially difficult is the planning of a complex 3D procedure based solely on the limited interaction available, such as rotation and slicing. In science, medicine and engineering, hand-drawn illustrations often include manipulating part of an object to depict the stages and the outcomes of a procedure or process. These illustrations help to uncover hidden features or reveal the spatial relationship between different components of the object.This research involves the exploration of a more "active" set of visualization techniques for 3D that mimic styles in illustrations and which will allow querying of 3D data using manipulations such as cutting, pulling and peeling. The techniques are based on the concept of "illustrative deformation". Illustrative deformation is a non-physically-based means for specifying and realizing visualizations that contain cuts, dissections, distortions, and various other forms of deformation that are not present in the original data. The deformation is represented through iconic operators which are applied to a 3D dataset much like a texture is applied to a polygonal model. By using inverse rendering and correct normal calculation of the newly created surfaces, high-quality illustration-like images can be achieved at interactive speeds. This research is investigating, developing and validating a 3D interaction paradigm through illustrative deformation.

图示变形教授D.银，部门电气和计算机工程，罗格斯大学，新泽西州州立大学研究摘要：3D数据（来自3D成像、模拟、传感）在许多科学领域，如医学、生物学、工程学、心理学、安全检查和考古学中很普遍。然而，对三维数据的有效探索仍然是一项具有挑战性的任务。尤其困难的是仅基于有限的交互（例如旋转和切片）来规划复杂的3D手术。在科学，医学和工程领域，手绘插图通常包括操纵物体的一部分来描绘程序或过程的阶段和结果。这些插图有助于发现隐藏的功能或揭示不同组件之间的空间关系的object.This研究涉及到一个更“积极”的3D可视化技术，模仿插图的风格，这将允许查询的3D数据使用的操作，如切割，拉和剥离的探索。这些技术基于“说明性变形”的概念。说明性变形是用于指定和实现包含原始数据中不存在的切割、解剖、扭曲和各种其他形式的变形的可视化的非基于物理的手段。变形通过图标操作符表示，该图标操作符应用于3D数据集，就像纹理应用于多边形模型一样。通过使用逆渲染和正确的法线计算的新创建的表面，高质量的投影图像可以实现在交互式的速度。这项研究正在调查，开发和验证一个3D交互范例，通过说明性变形。
