Title: Triangular mesh simplification algorithm based on vector angle
Abstract: The author proposes a 3D triangular mesh simplification algorithm with the method of vertex culling, which is based on the rule of vector angle. This algorithm includes the following steps in turn: calculating direction vectors generated by a random mesh vertex and the ones around it; recognizing and simplifying the planar areas in the mesh according to vector average angle; judging whether a vertex accords with the secure culling rule, which adopts the result whether the area where this vertex lies is smooth as a restraint to reserve the characteristic vertexes and then keep the visual features; after the step of vertex culling, conducting triangular mesh reconstruction on the polygons formed in the above steps to fill up the hollows. This algorithm achieves desirable balance in mesh simplification in the aspects of quality and efficiency.
