Illustrative Deformation

说明DEFORMATIONProf。研究摘要：3D数据（来自3D成像、模拟、传感）在医学、生物学、工程学、心理学、安全与筛查、考古学等许多科学领域都很流行。然而，有效地探索三维数据仍然是一项具有挑战性的任务。特别困难的是规划一个复杂的3D程序，仅基于有限的交互可用，如旋转和切片。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一个过程或过程的阶段和结果。这些插图有助于揭示隐藏的特征或揭示物体不同组成部分之间的空间关系。这项研究涉及探索一套更“活跃”的3D可视化技术，这些技术可以模仿插图中的风格，并允许使用诸如切割、拉伸和剥离等操作来查询3D数据。这些技术是基于“说明性变形”的概念。说明性变形是一种非基于物理的方法，用于指定和实现可视化，其中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。变形是通过应用于3D数据集的图标操作符表示的，就像纹理应用于多边形模型一样。通过对新创建的表面进行反向渲染和正确的正常计算，可以以交互速度获得高质量的插图样图像。这项研究是调查，开发和验证三维交互范例通过说明性变形。

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.
