Title: Free-Form Curves and Surfaces
Lecturer: Thomas Sederberg, BYU, USA
Abstract: This lecture will review Bezier curves and surfaces, B-Spline
(NURBS) curves and surfaces, Subdivision Surfaces, and T-Spline surfaces.
Some of the beautiful mathematics behind these representations will be
presented, and students will obtain a working knowledge of the subject.
Title: Real-time texture synthesis, theory and
practice
Lecturer: Sylvain Lefebvre, INRIA, France
Abstract:
A major difficulty in building vast, rich virtual worlds is the large amount
of content that is required, in particular 3d meshes and textures. It is
therefore not surprising that researchers in computer graphics started to
consider methods to automatically generate this content.
Textures in particular have received much attention: Images of materials
tend to occupy a large amount of memory and their content is often of a
stochastic nature. On the one hand this randomness makes them hard to
compress efficiently as images, but on the other hand one can hope to
describe their content through algorithms. However, being able to compute
textures of a given appearance only partially solves the problem: The
generated data must also be available in a form allowing for high quality,
interactive rendering.
In this course I will describe the major challenges we are facing when
synthesizing content for virtual worlds. I will focus on textures,
describing the main families of approaches for their synthesis. After
introducing of the main formulations of the texture synthesis problem I will
describe state of the art algorithms for generating, at runtime, novel
textures resembling a single example image.
Title: What do we do with all the photos?
Lecturer: Prof. Jiebo Luo, University of Rochester
Abstract:
Today there are massive amounts of photos stored online or in
personalarchives. They are largely under-utilized once people have viewed
and shared them online. In this talk, we introduce a number of ways to
increase the values of such photos, including collaborative photo sharing,
multimedia reliving, and computational photography.
Title: 快速弹性形变物理仿真技术

Title: 3D打印中的几何问题
Lecturer: 吕琳,山东大学
Abstract:
3D打印是采用分层加工、迭加成形的方式逐层增加材料来生成3D实体的制造过程,由于无需机械加工或模具,就能直接从计算机图形数据中生成任何形状的物体,3D打印能够极大地缩短产品的研制周期,提高生产率和降低成本。近年来,3D打印技术发展迅速,应用领域不断拓宽,其中的几何问题因涉及到打印材料、打印时间、成型强度等各方面,受到了广泛的关注与研究。本次课程将介绍3D打印的主要方法与技术、重点介绍其中相关的几何问题,并讨论几何处理在模型内部结构优化、打印方向选择、多模型打印布局优化等方面的应用。
Title: 3D打印:三维智能数字化构造
Lecturer: 吴怀宇,中国科学院自动化研究所
Abstract:
3D打印以经过智能化处理后的3D数字模型文件为基础,通过逐层增加材料的方式来构造任意复杂的3D实体形状。不同于以往产品千篇一律的“大规模生产”模式,3D打印使得每个产品都能有所不同的“个性化定制”成为可能。其中,3D智能数字化技术是3D打印实现“低成本大规模定制”、区别于传统“昂贵费时的手工化定制”的基础和关键所在。本讲座首先对3D打印的原理、结构和工艺方法作了介绍,包括对十多种典型的成形工艺进行优劣分析和比较。另一方面,如何开发出能够激发用户个性化创造热情的“杀手级软件应用”,让广大用户能够“随时随地”创建出各种各样的3D数字化形状,将是引爆3D打印“无所不在地”(ubiquitously)走进千万家庭的关键之一。因此,作为本讲座的重点,将对个性化数字形状生成的各种智能方法进行详细阐述,包括个性化特征检测与匹配、个性化形状建模与扫描、个性化形状编辑与合成、个性化形状分析与处理、个性化形状检索等。

Lecturer:
宋鹏,中国科学技术大学
Abstract: 三维自锁结构(Interlocking
Structure)是一个由多个拼块组成的、可拆解和组装的三维几何模型。所有组装在一起的拼块相互锁住,使得整个模型非常稳固。三维自锁结构的应用非常广泛,包括三维拼图游戏、家具设计、三维打印等。目前生成三维自锁解构的方法主要基于手工设计,但该方法费时耗力且只适合少量拼块组成的模型。本课程介绍在给定三维形状上自动生成三维自锁结构的计算方法,以及该方法在实际生活中的应用。
