本文介绍晶体学点群的计算机表达和交互设计。软件采用计算机三维动画和三维交互技术动态描述了晶体的宏观对称元素和对称操作,交互展现了32种晶体学点群的对称元素,图、文、声、像并茂为学习者提供了一种生动直观、可交互控制的自主学习环境。软件采用3DS MAX建模,Photoshop CS作图片处理,Cult3D设计三维交互,Director组装软件素材。 This article introduces the crystallographic point group computer representation and interaction design. Software uses computer 3D animation and 3D interactive technology to dynamically describe the macroscopic symmetry elements and symmetrical operation of the crystal and interactively display the symmetrical elements, groups, texts, sounds, and images of 32 kinds of crystallographic point groups, providing a vivid Intuitive, interactive control of the independent learning environment. The software uses 3DS MAX modeling, Photoshop CS for image processing, Cult3D design 3D interaction, Director assembly software material.
