摘要

Many fields in science and engineering are utilizing virtual reality as a tool which allows them to accomplish tasks that would otherwise be elusive due to cost, safety, etc. Specifically, the use of haptics, or force feedback, has become an ever increasingly popular tool in virtual reality. In order for haptics to be valuable, in many cases the accuracy of what the user feels is of paramount importance. To achieve such accuracy, virtual reality simulations must be capable of achieving three goals-real time performance, physical accuracy, and volumetric modeling. This dissertation introduces a methodology, called the Atomic Unit Method for achieving real time, physically accurate, volumetric virtual reality simulations. It works by dividing objects into a lattice of discrete volumes, which pass information to each other about force and displacement. The effects of forces that have been sent through this lattice are then aggregated to achieve global behavior based on local behaviors. To achieve this local behavior, an object oriented approach is utilized wherein each discrete volume is represented by an object.; The methodology is implemented in an idealistic setting, and also using real world data. The performance of this approach is validated both numerically and with human subjects assessing the sensations it produces haptically.
