报告题目：Computer Graphics as Tools for Artistic Design

摘要：Computer science has developed into a popular and relatively matured

discipline whose frontier research requires theory and technologies

from and has impacts on many other disciplines including science,

engineering, social science and arts. In this talk, we report a current

research project of ours in computer graphics.  We show how fundamental

concepts in classical mathematical theory are nicely applied in

computer graphics applications, which resulted in the first

topologically robust graphics modeling system, and graphics softwares

that are powerful and can be used to create topologically complicated

3-D graphics shapes. The graphics softwares have been successfully used

in architecture designs by architects, and in designing and creating

subtle and beautiful artistic patterns and figures by artists.

报告题目：fabrication-aware geometry processing

摘要：As the fast development of 3D printing technology, it is now possible

to produce 3D-printed objects with exceptionally high fidelity and

precision. However, it is lack of tools to predict or fast-preview of

the physical properties of the printed 3D objects, such as its

structure stability, motion. Fabrication-aware design technique is to

integrate simulation into geometry design so that the user can monitor

or control such physical properties during the design. It opens up an

interesting research direction for the user to explore design manifold

with the physical feasibility constraint.

报告题目：三维模型彩绘交互技术

摘要：三维模型彩绘是三维模型表面属性（如颜色、法向、置换贴图等）的交互式编辑

技术，是计算机图形学的关键技术之一。研究人员致力于研究自然高效的三维模

型彩绘交互界面，将三维模型表面属性编辑技术普及到普通用户。具体地，本报

告针对三维模型交互中经常遇到的遮挡难题，与指定纹理贴图约束众多的交互难

题，分别提出了可视性层次结构与基于笔画的局部参数化等解决方案，实现了高

效易用的三维模型彩绘交互界面。

报告题目：三维形状的对称性分析与应用(Symmetry in 3D Shapes: Analysis and Applications)

摘要：近年来，对称性分析与应用在计算机图形学和计算机视觉领域得到了广泛关注。

对称性是连接三维形状低层几何属性和高层语义信息的桥梁。因此，对称性分析

是形状分析的核心问题之一。本次报告将对三维形状的对称性分析做系统性介绍

，其中重点介绍对称检测的难点问题——内蕴对称分析。报告第二个部分将介绍

对称性分析在数字几何处理中的应用。

报告题目：Human Body Geometry and Motion Recovery from a Single Depth Camera

摘要：We present a full-body human geometry and motion recovery approach

using a single depth camera. We first build a prior template by

capturing a subject in a stationary reference pose in front of the

camera. Subsequently, intrinsic body shape is determined with the help

of the template using a modified parameterized SCAPE model, which is

also constrained according to height, weight, and gender. We replace

the pose variation deformation in the original SCAPE approach by linear

blending skinning (LBS) for speed; it also has simple implementation

and good deformation qualities. The parameters of LBS are learned from

a human body training dataset, and directly applied during motion

recovery. This modified SCAPE model allows a moving human body be

reconstructed in realtime from dynamic depth data.
