This paper proposed an improved subdivision algorithm that based on quadrilateral mesh. Firstly, we implement quadrilateral mesh preprocessing to polygon mesh by paired method, and then adopt the strategy of slowing growth in the number of edges. After each subdivision, the number of meshes increase approximately 1 times, the result of twice subdivision nearly equal to the traditional 1-4 subdivision once. The subdivision surface is generated by the improved algorithm has C2 continuity in the regular vertex and C1 continuity in the extraordinary vertex. The experiment show that the improved algorithm is effective, it can slow down the growth rate of meshes effectively, be good to the multi-resolution analysis of model, can keep the character of original model splendidly, and make the generated surface smooth and connection.
