Abstract

We present an immersive visualization system for visual analysis of casting flow and solidification using a VR display. Metal flow and solidification are simulated using finite-difference (FDM) software. From the simulation results we extract the surface of the casting on a rectangular mesh and give each facet a color corresponding to the temperature at that position. We then transfer this color data to the original STL model of the casting. The surface of the STL model is first subdivided. Then, for each point on this fine mesh, the nearest point on the grid surface model is determined, and the color is transferred to the STL model. A Projection Table is used to display stereoscopic images of the model to provide an effective visual analysis environment.
