Design and Realization of 3D Graphics GeometricInformation Demonstration System Based on Direct 3D

在多媒体时代,3D模型不断涌现,为人们提供了更加优质的图形画面效果。为了进一步提高人们的视觉体验,现利用Direct3D相关技术,设计一款功能完善、实用性强的三维图形几何信息演示系统。首先,根据系统设计原理及模块,完成对系统信息提取模块设计。其次,从几何信息高亮显示、旋转、平移及缩放等交互模块、图元拓扑结构信息展示模块、索引数据模块、顶点数据展示模块、信息交互模块等模块入手,完成对系统信息演示模块设计。最后,探讨了系统功能实现。设计的三维图形几何信息演示系统运行正常、可靠、稳定, 各个功能模块均满足设计相关要求。

In the multimedia era,3D models continue to emerge,providing people with more high-quality graphics effects.In order to further improve people's visual experience,we use Direct3D related technology to design a 3D graphics and geometric information demonstration system with perfect functions and strong practicability.Firstly, based on the system design principle and module,the system information extraction module is designed;Secondly,starting from the geometric information highlighting,rotation,translation and zooming and other interactive modules,graphic topology information display module,index data module and vertex data display module,information interaction module and other modules,to complete the design of the system information demonstration module;Finally,the realization of the system function is discussed.The results show that the 3D graphics and geometric information demonstration system designed in this paper runs normally,reliably and stably,and each functional module meets the relevant design requirements.
