There is not a clear consensus on the categorization framework of the educational values of the history of mathematics. By analyzing 20 Chinese teaching cases on integrating the history of mathematics into mathematics teaching based on the relevant literature, this study examined a new categorization framework of the educational values of the history of mathematics by combining the objectives of high...
In this thesis, taking Guishan Han tomb 3D Visualization Simulation System as an example, an algorithm named half edge collapse mesh simplification based on constrained quadric error metric method(HECMSA-CQEM)is used to simplify the geometric models. Taking advantages of the progressive mesh, half edges are collapsed under constraining of quadric error metric method. As shown in experiment, the HECMSA-CQEM...
In this thesis, taking Guishan Han tomb 3D Visualization Simulation System as an example, partial instance technology based on level of detail (PIT-LOD) is studied. The ¡®rea-listic' and ¡®real time' of VR system could be reached at the same time by combining these two approaches together. Based on study of level of detail (LOD) and instance technology, the PIT-LOD is further discussed. Firstly, objects...
