摘要

自1985年Peachey和Perlin在研讨会论文中介绍它们以来,体纹理已经成为一种流行的建模工具。它们不仅用于创建复杂和一致的纹理,还用于在各种材料(如石头)上渲染风化效果,Dorsey等人在1999年证明了这一点。虽然可以纯粹程序化地生成体纹理,但最近对2D纹理合成的兴趣激发了对从物理示例合成体纹理的兴趣。我将介绍一些应用程序,其中来自样本的体积纹理很有趣,一些估计它们的方法,以及一些评估合成体积是否正确的早期工作。Holly Rushmeier是耶鲁大学计算机科学教授。她目前的研究重点是形状和外观属性的扫描和建模,以及在文化遗产中的应用。她教授研究生和本科生的计算机图形学和可视化课程。她分别于1977年、1986年和1988年获得康奈尔大学机械工程学士学位、硕士学位和博士学位。在获得学士学位并于1983年返回研究生院期间,她曾在波音商用飞机公司和华盛顿天然气公司担任工程师。在获得博士学位后,她曾在佐治亚理工学院,国家标准与技术研究所和IBM T.J.沃森研究中心任职,然后于2004年加入耶鲁大学。她研究了许多不同的渲染问题,包括全局照明和色调再现。在NIST和IBM,她研究了从工程到金融等领域的各种数据可视化问题。她最近的工作主要是在获取生成逼真的计算机图形模型所需的数据领域,包括在IBM和埃及政府的一个联合项目中创建米开朗基罗的《佛罗伦萨圣母像》的数字模型和埃及文物模型的项目。1996年至1999年,他担任ACM Transactions on Graphics的主编,目前是ACM Publications Board的成员。她还曾担任IEEE可视化和计算机图形学交易的编辑委员会成员,她目前是IEEE计算机图形学与应用,计算机图形学论坛和ACM应用感知交易的编辑委员会成员。1996年,她担任ACM SIGGRAPH会议的论文主席;1998年和2004年,她担任IEEE可视化会议的论文联合主席;2000年,她担任Eurographics Rendering Workshop的论文联合主席。2005年,她担任IEEE可视化和3DIM会议的联合主席。她还曾在多个项目委员会任职,包括在SIGGRAPH、IEEE可视化、Eurographics、Eurographics渲染研讨会和图形接口委员会任职多年。

Modeling Volume Textures - Keynote
Since their introduction in semina1 papers by Peachey and Perlin in 1985, volume textures have been a popular modeling tool. Not only are they useful for creating complex and consistent textures, they are needed for rendering weathering effects on various materials such as stone, as demonstrated by Dorsey et al. in 1999. Wile it is possible to generate volume textures purely procedurally, recent interest in 2D texture synthesis from example has spurred interest in synthesizing volumetric textures from physical example. I will present applications where volume textures from samples are of interest, some approaches to estimating them, and some early work on evaluating whether the synthesized volumes are correct. Short Biography Holly Rushmeier is a professor of computer science at Yale University. Her current research focuses on scanning and modeling of shape and appearance properties, and on applications in cultural heritage. She teaches courses in computer graphics and visualization at both the graduate and undergraduate levels. She received the BS, MS and PhD degrees in Mechanical Engineering from Cornel1 University in 1977, 1986 and 1988 respectively.
