The evolution of virtual reality and 3D computer graphics has made digital visual simulation increasingly popular. Realistic visual simulation as in urban planning requires large-scale virtual environments using a large number of objects and space expansion. In such large systems, it is difficult to get information on the overall view and status using conventional representation. Effective representation and interaction must be considered for objects in a large-scale virtual environment. We propose large-scale 3D virtual environment interaction using multiview representation incorporating local and global views. Local view displays the detailed environment and global view provides a simple small-scale model of the environment giving users an overall view and status. Gesture interface enables them to directly interact with the model using natural and intuitive actions.
