| The kernel technique of 3D scene establishment used in 3-Dimension TWR(control tower) Control Simulation Training System(TCSTS) was studied in the thesis, which emphasize on the construction methods of 3D model, 3D terrain and some special effects in software development.The thesis consists of 4 parts. Brief introduction of some basic knowledge and the develop tools of graphics was given in the first part. The second part introduces the methods of creation and using manner of 3D model. Comprehensive studying and discussing how to establish the random and practical terrain was included in the third part. In the fourth part, how to define and use the lights in OpenGL and in Tower Control Simulation System is explained firstly, sequently, the ways of construction of some special effects like cloud and fog used in this system are discussed in detail. In the end of each chapter and the article, some pictures of simulation effect are showed. |
