- W99374211 abstract "This paper describes how typical vehicle simulations require numerical integration at an integration time step of no larger than 0.01 seconds, usually less than half that time. This does not leave enough time to carry out the complex calculations required for detailed collision calculations in real time. This paper presents a method that strikes a compromise, which, although not carrying all the detail necessary for very accurate collision calculations, allows useful simulations to proceed in real time. The method has three parts: collision detection, estimation of the momentum transfer expected to result from the collision, and application of forces to provide the desired momentum transfer. The method uses a common scene graph for collision detection, which allows the system to work with most of the common scene database formats without the need of specialized preprocessing. All of the collision detection and response calculations employ open-source code and are designed to work well at speeds required by real-time vehicle simulation. Examples based on the VDANL vehicle dynamics simulation illustrate the utility of the methodology." @default.
