Examination for realization of Virtual Environment using data of power plant

Abstract

Various techniques to create virtual environment using design data of power plants are presented.
In order to realize interactive operations on virtual environment, it is necessary to achieve the real-time processing of drawing and interference check. However, real-time processing is very difficult in the case of large-scale and complicated buildings like power plants, because of the large number of shapes.
In this paper, we propose the abbreviation drawing technique that changes the drawing area dynamically to keep the drawing time constant, and the fast interference check technique that utilizes the hardware projection processing. And it is confirmed that the processing can be realized within 200 msec by applying the prototype system to real power plants.
Moreover, we propose the navigation technique that enables users explore inside of the complicated virtual power plants and show the rapidness and effectiveness of the technique.
