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.

开发了一个基于图形工作站的景观仿真系统，可以在虚拟空间中高效地构建大型建筑物。此外，还开发了一些操纵虚拟对象的基础软件。(1)景观生成系统直接在三维空间中生成虚拟城镇中的树木、建筑物、道路等景观。(2)步行穿过规划区我们可以自由地步行穿过规划区。图形工作站中的高速绘制引擎有助于在观察方向改变时生成真实的三维图像。(3)景观数据的管理景观数据是有效地管理和传输从数据生成系统和步行通过系统。景观数据包括对象形状、纹理、对象组信息、渲染属性等。(4)虚拟空间中的基本操作功能为了使景观规划更加自由，基本操作功能是必需的。我们为此开发了几个交互式操作功能。
