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.

作为海岸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性的因素具有重要作用，已经开发了基于计算机图形技术并结合声音处理系统的景观和听觉环境的动态模拟器。为了在工作站（20MIPS，32Mb）上实现模拟器系统，开发并集成了多种有效的软件，以减少计算时间和存储空间。软件方面最突出的改进之一是在破碎波表达技术上，巧妙地引入了凹凸映射CG技术，并简化了破碎波场的计算方法。通过对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。
