3d Geometric Model of Transparent Tower Equipment Display in OpenGL

摘要

It's difficult to describe the 3d geometry and to establish the 3d model of tower equipment in OpenGL. High-level command functions to define complex three-dimensional modeling is not provided in OpenGL. This paper introduces 3d model of the tower equipment how to display dynamically in OpenGL. Interface of OpenGL import 3d model is description in detailed. Storaging format and reading file of STL (Stereo Lithography) are elaborated. How to build the 3d model is descripted. When tower equipment displayed dynamically, what is the key step to establish the model of tower equipment. The dynamic model of the whole tower equipment is displayed, in order to see clearly the structure of tower equipment.
