A PC-Based Platform for VR Development-PCVRS

摘要

This paper discusses a PC-based platform for Virtual Reality (VR) system development-PCVRS. Comparing with the same kind of systems abroad, this paper analyses in detail the features of PCVRS on interactive functions and opening capabilities. As for interactive functions, PCVRS added the "Pick & Play" interaction, supplied voice as an additional interacting modal and implemented multimodal interaction. The opening capabilities of the system is mainly showed by its support for VRML which is widely used as virtual reality modeling language in Internet. The ssytem even supplies abstract modeling data structure as a unfirom interface for various kinds of 3D scene data. By introudcing one of the applications developed on this platform, we also tested the performance of this system. The t est result shows that for those applications where scenes are not very complicated and the output requirements are not very high, PCVRS has a good interactive permance.
