ACMSIGGRAPG 2004 Talk: The introduction of programmable Graphics Processing Units (GPUs) and the addition of procedural shaders to the Web3D standard X3D provide us with new techniques to develop real-time Web based visualization. The only problem is we can not assume all the users in the same enviroments. That means different users might on different operating system, might use different venders graphics card. The fact is different vender's graphic card supports different shading languages. So what did we do is conversion. We created a platform for reading in different shaders in Cg, OpenGLSL, etc, converted it into XML format X3D, which can be shown on the web. When the user want to display the shader into their local machine, The converter will translate it to into the according shader format that supported by user's particular machine.

Siggraph talk ACMSIGGRAPG 2005 Talk: The topic is continuing the 2004 topic. We created a framework for translating the multiple language into diffrents format regard ing the user's hardware. In this paper we discuss the applications of these techniques to bioinformatics and chemistry visualization, specifically the visualization of large biomolecules. By using procedural shaders, we are able to produce higher quality visualizations with minimal performance penalty. We have developed methods to automatically convert from the standard bioinformatics PDB format to CML and then to X3D. The procedural shaders are automatically inserted during the CML to X3D conversion. This provides higher quality images and leads to future possibilities of more flexible and enhanced visualizations.

Siggraph talk MEC 2006 Talk: Create Molecular Models for Chemistry or Biology Classes Taking advantage of Web 3D and shader technology, we present an approch to create a real-time interactive and realistic image quality 3D molecular structure for Biologo and chemistry class. A web based Multi-user shared envirement for these molecular structure also will be shown.
