It is important to represent amount abstractly or invisible data by pictures and mutual control , with the aid of computer graphics and image process techniques , visualization not only provides convenient model material , but also is helpful to the following data analysis , which can make all information to be displayed directly , then discovery and analyze problems correctly . it is a important aspect to make information visualized in the field of geophysics and information technique 在地球物理与信息技术领域,将科学计算中产生的大量非直观的、抽象的或者不可见的数据,以图形图像的形式,直观、形象地表达出来,除了可为工程设计提供方便好用的模型资料,而且可为下一步的数据解释分析奠定基础,使工作者直观地看到地质现象的几何形态、相互关系和分布,从而准确的发现问题、分析问题,实现信息的可视化是其研究的一个重要方向。
The research contents in this paper are based on a nsfc project ( grant no . 59875088 ) , which needs that the sheet metal is used as modeling materials for rapid manufacturing of metallic functional part . in this paper , the objective and the value of the project are put forward and the slicing process of metallic functional part is studied based on new lom 本文根据国家自然科学基金项目的要求,以薄金属板作造型材料,提出了本课题的研究目的与意义以及本文的主要研究内容,开展了基于新lom的金属功能零件分层快速制造的分层处理研究。
