As one of powerful tools for the esthetic design in coastal space, where waves and their sounds have significant roles as factors constituting amenity of the space, a dynamic simulator of landscape and auditory environments has been developed, being based on Computer-Graphics techniques and incorporating a sound-processing system. To realize the simulator system on a work-station(20MIPS, 32Mb), several efficient softwares have been developed and integrated to reduce computational time and storage domain. One of the most outstanding improvement in software is made on the technique for breaking-wave expression by introducing ingeniously a bump-mapping CG technique with a simplified evaluation method of breaking wave field. The validity and applicability of the present system have been confirmed through an application to a specific plan of construction of artificial beaches in Tsuda coast, Kagawa Prefecture.

作为沿海空间美学设计的有力工具之一，波浪及其声音作为构成空间舒适度的因素发挥着重要作用，景观和听觉环境的动态模拟器已经开发出来，它基于计算机图形学技术并结合了声音处理系统。为了在工作站上实现模拟器系统（20MIPS，32Mb），开发并集成了几种高效的软件，以减少计算时间和存储空间。软件中最突出的改进之一是在破碎波表达技术上，巧妙地引入了凹凸贴图CG技术和简化的破碎波场评估方法。通过香川县津田海岸人工海滩建设具体规划的应用，证实了本系统的有效性和适用性。
