Modeling Of Molecular Visualization And The Software Implementation

With the development of bioinformatics and bioinformatics database, molecular 3D structure visualization plays a more and more important role in the analysis of bioinformatics. Protein molecular visualization software HJMV is based on a 863 program —— Bioinformatics Secondary Database of Proteins related with Selenium, providing with a platform for interactively viewing the 3D structure of molecules in various modes.The development of visualization system is always the process of filtrating the original data, mapping, rendering and displaying, and receiving feedbacks. HJMV molecular visualization software also includes the modules of PDB File Loader, Molecular 3D Structure Scene Graph Building and Rendering, and Main Event Handler.The 3D structure of protein molecule is stored in the PDB file in a special format, which could be loaded and understood by HJMV software. For the hiberarchy structure of molecules, HJMV builds the scene graph of molecule by geometry modeling based on Java and Java3D, displaying the structure of molecule by rendering the scene graph according to the structure information. The motion modeling of molecule meets the needs of interactive operation for the molecular coordinate transformation, such as rotation, transformation and scale. HJMV is published by being embedded in the web as an applet, and integrated in the Bioinformatics Secondary Database of Proteins related with Selenium.High performance is needed because of the large amount of atoms and the real-time interactive operation. Several improvements are made for the two problems of stronger loading function for large molecule and shorter response time for interactive operation. After tests, HJMV performs better than the similar molecular visualization software on the same platform.
