Research and realization of X3D-based simulation visualization supporting service

X3D is the open standard for real-time 3D communication, which integrated XML, Java and network streaming technology. And Grid technology tries to build the dynamic virtual organization based on distributed, heterogeneous and autonomous network resources for resource sharing and collaboration. X3D technology, grid technology and J2EE technology were integrated to construct the simulation visualization environment architecture and the simulation visualization supporting service. Different 3D models (such as airplanes, terrains, special effects, etc.) could be accessed, shared and assembled though Web browser. 3D visualization simulation applications could be customized for the fast construction of simulation virtual environment. The simulation visualization environment architecture and the key technologies of service realization were introduced in detail.
