Research On Three Dimension Visualization Technology Based On OpenGL

With the development of computer science, especially the three-dimensional technology, visualization technology has been widely used in various fields. In the course of developing the visualization system, editing of the three-dimensional(3D) model and its scene are becoming important tasks.we have studied the saving format in depth regarding different type of files and designed the saving data structure accordingly in the program, which enable the read and display of different type of files a reality,and realized monitoring of editing, transferring and rotating as well as zooming of the importing object. Finally carried out the simulation of generating, exercising and its disappearing process for the fountain particle system,further more,achievement of simulating fractal terrain have been made with the help of diamond-square technique.During the studying of this thesis, we have successfully made the transferring and rotating as well as zooming of the 3DS models a reality.through the jointly utilization of Visual C++ and OpenGL, we have made complicated moving object simulation and three-dimensional terrain becoming real. Through which we have tested the correctness of numeration and verisimilitude of observation. And omnidirectionally displayed the model with the help of virtual ball technology.
