Study on Landscape Simulation for Large-sized Buildings

点击翻译按钮获取中文摘要

A landscape simulation system on a graphic work station has been developed, with which we can construct large-sized buildings efficiently in a virtual space. In addistion, some fundamental software in order to manipulate virtual objects have been developed.(1) Landscape generationSeveral parts in a virtual town such as trees, buildings and roads are designed directly in a 3-D space in this system.(2) Walk through the planned landscapeWe can walk through the planned area freely. A high speed rendering engine in a Graphic work station helps generating real time 3-D images when the viewing direction is changed.(3) Data management for landscapeLandscape data are efficiently managed and transferred from data generation system and walk through system. The landscape data include object shape, texture, object group information, rendering attributes, and so on.(4) Fundamental manipulation functions in a virtual spaceFundamental manipulation functions are necessity in order to make a landscape planning more freely. We have developed several interactive manipulation functions for this purpose.
