摘要	In order to solve the problem of over-subdivision of Fast Adaptive Segmentation (FAS) algorithm, a dynamic adaptive feature subdivision method is proposed. First, the Feature Processing Unit (FPU) is constructed to generate the dynamic subdivision factor for the irregular block. The subdividing depth of the feature block is calculated and the irregular block of the feature region is refined according to the Catmull-Clark subdivision rule. Then, the number of blocks is controlled for Graphics Processing Unit (GPU), the block buffer and subdivision table are established to deal with each level of the same type of blocks in parallel, which improves the speed of subdivision and rendering. Finally, the data structure of the traditional FAS is expanded to generate new subdivision tables and drawing tables, which support the dynamic subdivision and real-time rendering of blocks. Experiment results show that the structures of the improved subdivision table and rendering table can guarantee the dynamic feature of the subdivision and the real-time rendering. Compared with the traditional FAS, the proposed method can ensure the drawing accuracy of 3D surface model, and increase the drawing speed by 28%, which is better in real-time performance than traditional FAS. 2018, Editorial Board of Jilin University.
