A scene graph based visualization method for representing continuous simulation data

This paper proposes a scene graph based visualization method that can verify time-varying continuous analysis simulation in a virtual reality (VR) environment by using the computer-aided engineering (CAE) data of structural analysis in product development. In previous research, the use of CAE analysis data has been problematic because of the lack of any interactive simulation controls for visualizing continuous simulation data. Moreover, the research on post-processing methods for real-time evaluation of CAE analysis data has not been sufficient. We therefore propose a scene graph based visualization method for representing continuous simulation data. The method can continuously visualize static analysis data independently of any timeline; it can also continuously visualize dynamic analysis data that varies in relation to the timeline. The visualization system for continuous simulation data, which includes CAE2VR Middleware that interfaces with various formats of CAE analysis data as well as functions for visualizing continuous simulation data and operational functions, enables users to verify simulation results with more realistic scenes.
