Study On Three-Dimension Visualization Of Engineering System

This thesis expatiates on the basal theory about three-dimension visualization of engineering system and the priciple ,method,key technology about development of three-dimension visualization of engineering system.According to the characters of three-dimension engineering, it designs data structure and data model by the method of OOP.Data structure of OOP is applied to the modelling based on graphics.It realizes the display of three-dimension graphics in engineering. The system can import/export 3DS files. It realizes selection, feedback of 3D shape and the management of 3D shape's properties;3D shape frome 2D contour lines and the medial axis of a convex polygon and an arbitrary simple polygon are discussed.
