A pseudo-immersive virtual environment - A framework for modelling sheet deformation

This paper presents a real-time, computationally inexpensive environment for accurate simulations of sheet materials on a personal computer. The approach described differs from other techniques through its novel use of multilayer sheet structures. The ultimate aim is to incorporate into the environment the capacity of simulating a range of temperatures. A pseudo-immersive "Window on World" (WoW) environment is used to handle the implementation of the real-time, aesthetically accurate deformation algorithm (MaSSE-Mass-Spring Simulation Engine). The motion of the sheet is controlled by simulated gravity and through its interaction with objects that have been inserted into a virtual room. In addition, the WoW interface is used to adjust environmental parameters dynamically and adjust the scene viewing perspective. An obvious use of the environment is centred on mechanical engineering-based real-time simulations of heat-sensitive sheet materials. This would allow for a wide range of applications in virtual manufacturing including the clothing industry and hostile environments. © Springer-Verlag London Limited 2004.
