3D Data Progressive Compression: Summer of code 2006 LG3D^? proposal

Description

This idea is to solve the two challenges in the exhibition and publishing of huge 3D data: (1)the rendering efficientcy of the client's graphics hardware. (2)the storage capacity limit of the local machine and the bottleneck of network bandwidth. The work mainly focuses on the incorporation of geometry compression and data transmissin over the Internet in the web browser of the lg3d. The system will provide a high-efficient methods of compressing huge 3D data and progressive transmission it over the Internet without time-delay in the local web browser.

Derivables.

• Project documentation : source code, general description, design hints etc.

• Project Core: system functionality classes.

• Serveral demos: provide serveral examples(including models and other resources) for the demo.

Tentative Schedule

• (1 week ) Get used to the LG3D^? enviroment (0% completed)
• (1 weeks) System design (90% completed)
• (2 weeks) First iteration : geometry-driven compression coder implementation(90% completed) and fixing some bugs.
• (1 week) Second iteration: Progressive transmission implementation(90% completed) and fixing some bugs.
• (2 week) Third iteration: Intergrate it with lg3d.
• (1 week) Final iteration: Test and fix bugs.
• (1 week) Documentation : complete the documentation.

Total: 7-8 weeks

Background

• Education: * Ph.D., School of Computer Science & Engineering, Beihang University, September 2004 – present. * M.S., School of Computer Science & Engineering, Beihang University, July 2004 (granted to Ph.D in advance). * B.S., School of Computer Science & Engineering, Beihang University, July 2002.
• Experience: * As a team leader of DM Group in Virtual Reality Laboratory, Beihang University (the key laboratory of Education Ministry). * Research in the area of 3D mesh compression, Digital Geometry Processing (DGP), technologically paving the way for the application of funds from the National Natural Science Foundation of China. * Participate in the project of Virtual Olympic Museum run by the Ministry of Science and Technology and the Municipal Government of Beijing. As one of the 20 key projects for the 2008 Olympic Games, the aim of this project is to build a first-class world virtual museum, contributing to the Olympic of science and technology. I’m working as the student group leader in the overall design of this project and have finished the set-up of technology platform as well as 3D sub-systems “A Motion Capture Based Seamless Human Animation over the Internet: Virtual Long Jump in Ancient Greece”, “Virtual Wuqinxi”, “Virtual Skee”, “Virtual Badminton”.
