CG visualization of large scale city planning needs a lot of scene data, and data input has been a bottleneck in CG simulation. This paper describes an interactive scene data input system for virtual scene simulation. This system provides the functions of terrain data editing, automatic generation of road description data, design and arrangement of buildings, arrangement of trees, generation of ground surface data, and arrangement of special shape data modeled by other CAD systems. With this system, one can construct city scenery in a virtual space directly within a short time, while evaluating it.
