A virtual reality application for software visualization

Since a power network control system constitutes a large-scale computer network, intricate functions of software such as processing synchronization and data transmission among the constituent computers are required for improvement of system performance and efficiency. Methods for the support of overall large-scale system design are still scarce. Conventional text-oriented tools are insufficient to design, construct, and maintain large and complicated systems. As a means for solving this problem, an analytical method has been designed based on computer graphics visualization of static structural data and execution trace data of a software application´s functional units. Prototyping tools for the development of software, enabling the direct manipulation of graphical elements through user-machine interfaces based on virtual reality technology, have been developed
