Postdoc: Material Models for Computer Graphics

9806139麻省理工学院朱莉·多尔西博士后：计算机图形学的材料模型真实感图像合成是计算机图形学中最基本的问题之一，有着广泛的应用。图像合成中缺失的一个重要组成部分是气候变化的影响。计算机图形学中现有的材料模型假定材料处于原始状态，但很少出现这种情况。这项研究计划致力于开发适合图像合成要求的材料的计算机图形模型。这项研究将解决这个问题的三个关键方面：(1)材料的分类--将对各种材料进行研究，以便设计出专门针对计算机图形学的材料分类。(2)材料模型--将开发新的材料模型，它将能够维持一系列外观。(3)对象和材料的组装--将设计数据结构来处理复杂几何和材料的复杂组装。这位博士后助理将在麻省理工学院新的计算机图形学研究小组发展的形成阶段发挥关键作用。该助理将带来建模和纹理方面的专业知识，将在研究项目上与教师合作，并将为学生的研究提供领导。

9806139 Dorsey, Julie Massachusetts Institute of Technology PostDoc: Material Models for Computer Graphics Realistic image synthesis is one of the most fundamental problems in computer graphics with a wide variety of applications. An important component that has been missing from image synthesis is the effect of weathering. Existing models of materials in computer graphics assume that the materials are in pristine condition, which is rarely the case. This research program focuses on the development of computer graphics models for materials, which will be suitable for the requirements of image synthesis. The research will address three critical aspects of this problem: (1) Taxonomy of materials --a study of a variety of materials will be conducted in order to devise a classification of materials that is specific to computer graphics. (2) Models for materials -- new material models will be developed, which will be capable of sustaining a range of appearances. (3) Assemblies of objects and materials -- data structures will be devised to handle intricate assemblies of complex geometries and materials. The postdoctoral associate will play a key role in the formative stages of the development of the new computer graphics research group at MIT. The associate will bring expertise in modeling and texturing, will collaborate with faculty on research projects, and will provide leadership for student research.
