A Method of Reconstructing a Virtual Gallbladder Geometric Model Based on OpenGL

Abstract:

The paper puts forward a method of reconstructing a vivid virtual gallbladder geometric modeling. We use Visual C++ to write import program, save the geometry information of gallbladder contour which is related to reconstruction, and discarded something irrelevant such as materials, textures and so on. In the process of reconstruction, it need to import the data of gallbladder contour vertexes and facets, but not to read the entire 3DS file again, which will undoubtedly save more time and benefit more to real-time interactive. Then we change the independent facets into an interrelated whole through indexing and finding out storage location of triangular facets vertexes in vertex array. So that we can change the position and the shape of the gallbladder by changing the coordinate values of vertexes.
