Study On The Algorithm Of Point Based Isosurface Extraction

In recent years, more and more researchers dedicate their efforts to the research of Point Based rendering technology and Isosurface extraction algorithms. This trend makes a new field of Point Based Computer Graphics which has proved to be of great importance in"Visualization in Scientific Computing"and has great potential in the storage efficiency and computing speed of Isosurface extraction.Meanwhile, with the great improvement in graphics'programmability, general purpose computing on graphics processors (GPGPU) is becoming a hot research field. Based on the advanced graphics'programmability, we can use graphics to solve the problems not only related to the display but also related to common calculating in stead of CPU. Now, GPGPU is being used widely and is greatly employed in the fields such as visualization, PC games, digital image processing, and emulator, scientific calculating, data searching and so on. Based on the rapid development of GPGPU, now, more and more graphic companies are paying much attention to the characters design, which can support more and more GPGPU programming features. So this thesis will include the implementation of GPU's great computing power to optimize our new algorithm.In the thesis, we will focus on the research of a Point-Based GPU accelerated Isosurface extraction algorithm which is mainly used in 3D reconstruction of medical image. The following parts illustrate the innovations:First, the traditional Isosurface extraction algorithms'result is represented by a huge number of triangles. Every triangle has three vertexes and three...
