摘　　要：介绍了在CATIA V5中创建物体三视图的虚拟投影体系模型图的方法.首先建立物体的实体模型,捕捉必要的视图图像,然后在实时渲染模块中利用盒形场景编辑器模拟投影体系,再将捕捉的视图图像作为背景贴图映射到虚拟投影面上,虚拟物体的正投影,实现了在CATIA数字环境下虚拟物体三面正投影视图的生成过程.该模型可以直观地展示获得物体多面正投影的过程,是利用CATIA V5模拟物体投影的有益尝试.A virtual projection system model of the object＇s three regular views was created in CATIA software. Firstly, creating parametrical solid model with CATIA software was created; secondly, images were captured by using Capture commands; then, a virtual projection system was created by means of Create Box Environment command with Scene Editor in Real Time Rendering and last background images were mapped into virtual planes of projection to establish the object＇s virtual projections. As a result, a model of the object with its projections was displayed on the 3-planes projection system in CATIA virtual digital environment. From this virtual projection system people can understand directly the process of getting the object＇s multi-view projections. It＇s proved to be useful and helpful of using CATIA V5 to simulate the object＇s projection.
