Novel hybrid polygon mesh simplification technology

The invention relates to a novel hybrid polygon mesh simplification technology. The technology comprises the following steps: data acquisition: acquiring 3D point cloud data packaged by OSGB and PLY; and packaging the corresponding grid data model dynamically according to the shape of the data. And model matching: enabling the encapsulation data to correspond to the node data type of the OSB, assigning the three-dimensional space point data of each grid model and the link condition between each point, and generating a corresponding grid data structure. And model drawing: drawing the generated grid data model through OSG and OpenGL (Open Graphics Library). And grid simplification: dynamically adopting different grid simplification algorithms according to different grid models. And grid subdivision: deepening the fineness of the grid model for the quadrilateral grid by adopting a quadrilateral grid expansion technology, and restoring the fineness of the original grid for the triangular grid by adopting a point
