应BETVTOR伟德app邀请，新加坡国立大学苏州研究院陈朝成教授来公司讲学，欢迎大家参加。
题目：图形处理及几何学
时间：2014年10月13日9：30分
地点：BETVTOR伟德app会议室（南一楼西433）
概要：GPU图形处理器现已不仅局限于其原有的功能，在显卡上也得到了广泛的运用。在商业应用上，它执行了综合的并行计算，从而可以以低成本最大化的提升处理速度。计算几何学研究几何对象的运算，应用于科学计算及娱乐（例如在游戏中的地形模型及冲突检测）方面。此次讲座将首先回顾GPU编程及计算几何学的基础知识，其次探讨运用图形处理器来解决及加速处理几何方面的难题（如凸核、泰森多边形、狄洛尼三角剖分等等），还将探讨运用图形处理器在解决几何问题时面临的主要挑战。
主讲人简介:陈朝成教授，新加坡国立大学苏州研究院（新国大苏研院）常务副经理。他所主管的教育与培训部门为新加坡国立大学和世界各地的老员工举办学术交流活动，为中国老员工开展短期培训课程，并为高校、政府和企业提供高端培训项目（包括公共行政、社会管理、城镇规划建设、房地产分析等课程）。
陈教授也是新国大BETVTOR伟德app的一名教授，博导。先后两次获得新国大优秀教学奖。长期以来，他积极帮助员工扩展视野和提高能力，例如与BETVTOR伟德app员工会合作开展员工课外活动，以及为员工参与学院教研工作提供机会。在他近年任职BETVTOR伟德app副经理（主管研究生教育）期间，陈教授负责管理研究生的学习和福利，并为招收研究生和深入了解他国教育系统而频繁访问亚洲及欧洲地区。

Synopsis:GPUs (Graphics Processing Units) as in graphics displaycards have been used extensively, beyond their original purpose, to performgeneral parallel computations in industrial applications to achieve good speedup at a low cost. Computational geometrydeals with computation involving geometrical objects with applications in manyscientific computations as well as entertainment (such as terrain modeling,collision detection in games etc). In this talk, we review some simpleknowledge of GPU programming and computational geometry. Then we will discusssome of our GPU approaches to solve, with good speed up, geometry problems(e.g. Convex Hull, Voronoi diagram, Delaunay triangulation). We will alsoreview some general challenges in the area of applying GPU to solve geometryproblems.
