Abstract. X3D is currently the Web3D standard for modeling and rendering 3-Dimention visualization models on the Web. And Grid is the new-rising Internet computing technology to integrate and share different computing resources. In this paper, the simulation visualization environment architecture was built and the simulation visualization supporting service was realized by integrating X3D technology, grid technology and J2EE technology. It can support accessing, sharing and assembling different 3D models (such as airplanes, terrains, special effects, etc.) though Web browser. It also facilitates customizing 3D visualization simulation applications and the fast construction of simulation virtual environment. The simulation visualization environment architecture and the service realization method are introduced in detail. Keywords: X3D; simulation visualization; grid technology; Web3D.
1 Introduction The visualization technology is one of the important components of M&S supporting technology. 3-Dimension scene rending and driving is the common way in simulation visualization applications, which realize the 3D display in the runtime process of simulation. Simulation visualization supporting environment is a common framework to support the collaborative modeling and simulation of 3D visualization applications, depending on the different visualization needs in M&S applications. Grid technology is a new-rising Internet computing technology to build the dynamic virtual organization based on distributed, heterogeneous and autonomous network resources for resource sharing and collaboration. Globus Project is one of the most representative grid projects, and at present it provides GT4 (Globus Toolkit 4.x) to support building grid applications [1]. X3D is the open standard for real-time 3D communication [2]. Based on VRML (Virtual Reality Modeling Language), X3D integrated XML (eXtensible Markup Language), Java and network streaming technology. So it can achieve more effective 3D computing ability, rendering quality and transfer velocity. It also has such benefits as platform-independent, component-based, more extensible and so on. All these facts of X3D technology provides an effective support for the research and realization of Web-based simulation visualization supporting service. J.-W. Park, T.-G. Kim, and Y.-B.

In the traditional simulation visualization application, the sharing and reusing of visualization models are not enough. There is no common supporting environment for developing simulation visualization applications. And for each application which has different application needs the development process always begins from scratch. So in this paper, the simulation visualization environment architecture and the visualization supporting service were researched and realized by integrating X3D technology, grid technology and J2EE technology. It can support users to access, share and assembly
