Advanced Visualization of Crashworthiness Simulations using Virtual Reality Techniques

Regarding the increasing complexity of computer simulations on one hand and the development of computer technology in the last few years on the other hand, the demand on new visualization techniques to analyze the immense amount of data originating from scientific calculations has reached new dimensions. In the case of crashworthiness simulations, expanding the effectiveness of traditional post processing techniques is one key to achieve shorter design cycles and faster time to market. A very promising approach, that benefits from the recent progress in software and hardware technology, is the use of virtual reality techniques. At BMW, in co-operation with the University of Erlangen, we developed the software system VtCrash, that performs a three dimensional visualization and allows the user to observe, enter and manipulate the visualized crash in a virtual environment. A key feature of VtCrash is the possibility, not only to look at the simulation, but also to immerse into a scene th..

Video Integration of PAM-VIEW Visualization Results

A very efficient way to analyze computer simulations is to integrate the visualization of the results into video sequences. However, most postprocessors available today in the area of car crash simulations do not support the direct assembly of images into video. We have developed a software tool that allows for the annotation of images with text and graphics in connection with the PAM-VIEW 1 postprocessing system. It also supports the manipulation of the images and the archiving of image sequences as video clips. This is achieved using digital image capture, image compression and image manipulation facilities. The design and implementation of this software environment is described in this paper. 1 Introduction At BMW, the PAM-VIEW postprocessing system is used to analyze the results of car crash simulations. PAM-VIEW is capable to display animations of the visualization of these simulations. The integration of the images together with synchronized time varying text had been achieve..
