| Abstract: | This paper introduces a 3D interactive graphic sys- tem based on CSG(constructive solid geometry)representation. There are two main algorithms included in the system.One is the interaclive input of 3D object model by input the primitive volumes directly from 2D orthographic cngineering drawings.The other is the general fast hidden line/face climination algorithm which gives some new methods,such as partial backface method,hidden face predic- tion method. |
