个人简介

1984年,贾金原教授毕业于内蒙古大兴安岭师范学校数学班,然后在林区中学任教(职业高中数学)四年。工作业余时间顽强自学,于1988年考入吉林大学数学研究所(计算几何专业)硕士研究生。1991年,来辽宁石油化工大学计算机工程系任教(讲师)。 1999年去香港城市大学计算机科学系访学,从事分布式虚拟现实,开始接触Web3D。2000年在香港科技大学计算机科学系攻读博士学位,2002年获得德国DFG Fellowship支持,赴Max-Planck- Institute Fur Informatik作访问学者,从事特殊曲面求交几何计算的研究。 2004年博士毕业之后,来到吉林大学珠海学院工作,筹建软件研究所,任常务副所长,开始从事WebVR应用与研究,提出了一整套轻量级WebVR应用开发模式,并成功地研发了多个网上虚拟互动展示系统。2007年作为学科带头人被同济大学软件学院引进,筹建图形图像研究中心,采用应用驱动的研究模式,坚持学术研究与工程应用两条腿走路的方针,作为顾问参与了网上虚拟上海世博会的建设工作,开始全面突破Web3D关键技术,针对一直困扰Web3D的数据瓶颈、网络传输瓶颈与网页渲染瓶颈这三大关键问题,提出了一整套轻量级Web3D虚拟世界的研究框架与理论。在学术上,带领团队分别在图形学、多媒体、虚拟现实、仿真、计算机网络、Web Services等与Web3D相关领域的权威期刊上发表了多篇高质量论文;在工程应用上,成功研发了若干典型示范轻量级Web3D系统,并在业界引起很大关注。并被多家高校与企业聘为特聘教授、首席科学家、学术顾问等职,基于所研究的轻量级Web3D关键技术,研发了轻量级3D场景的轻量化、流式化、细粒度化预处理管线,进而打造了轻量级Web3D素材库及基于草图的在线Web3D模型搜索系统。同时由将大规模虚拟场景的渐进式传输机制与对等传输机制有机耦合起来,有效提升移动互联网加载3D模型大数据的性能。最后基于云烘焙的轻量级Web3D渲染引擎将Web3D在线渲染效果大大提升。值此互联网+与VR+时代,项目团队先后研制各种“互联网+VR=WebVR”、“互联网+Game=WebGame” 与“互联网+BIM=WebBIM”示范型应用均在行业中引领最新技术潮流。 获奖经历 2017年,以《轻量级WebVR大规模可视化服务支撑平台》获得中国虚拟现实产业科技创新奖 2017年,同济大学优秀教师 2013年,上海科技进步一等奖(与上海博坤信息技术有限公司联合获得) 2007-2012年,连续六年获得同济大学优秀毕业设计指导教师
