【摘要】 三维建模技术可以真实地再现人们身边的物体,研究三维建模技术对于三维立体图像技术的进一步发展具有十分重大的意义。在水利领域,三维仿真越来越被重视,OpenGL是优秀且功能强大的图形库,文中利用OpenGL,采用基于三角剖分的方法对库区的地形进行建模,从而实现库区地形的实时仿真,对于更加复杂的三维实体可以采用先用3DMAX等专业的建模软件进行建模,再导入OpenGL以便简化建模过程,提高效率。实验结果表明采用这种基于三角剖分的方法来建模是可行的,文中给出了实例。更多还原

【Abstract】 The techonology of 3D modeling can reappear external things around us.The research of 3D modeling is very important to the further development of 3D volumetric graphics technique.In the field of water conservancy,the importance of 3D virtual reality has been realized in these years.OpenGL isa powerful tool.This paper analyzes 3D modeling methods based on OpenGL,using triangle-cutaway method,and then transform it into OpenGL program.Considered more complex object,people can simplify the process by using 3DMAX modeling,and then imported it into OpenGL.As the result,this method is feasible.更多还原
