基于图像表达复杂物体的方法研究

在虚拟现实应用中,传统的建模方法是用图形建模的方法对每一个物体进行建模。在场景中,往往有很多物体是非常复杂甚至难以建模的。为了使建模工作简化并同时保证逼真度,提出一种基于图像表达复杂物体的方法。可以对某个复杂物体拍摄或制作多张对应不同视点方向的图像,并且在程序中用图的数据结构管理。在漫游浏览时,再根据摄像机的当前位置确定显示对应视点方向的图像。这种方法既可保证场景的逼真度,同时又使场景得到简化,使系统的运行速度得到提高。

Research of Image-based Method to Express Complex Objects

The traditional method in virtual reality application is to model each object with method base graphics.It is often that many objects are very complex or even can't be modeled.In order to keep virtual scene simple but realistic,an image-based method is offered to express the complex objects.To Shoot orto make images corresponding to different viewpoints,and to manage them using graph data structure in program are discussed.When browing the right image can be displayed according to the current position of camera.The image-based objects can keep scene realistic and simple.It can increase the system velocity.
