摘要

Ased on the analysis that the application of the subdivision surfaces modeling technology is feasible in the three-dimensional geological modeling, and for the problem of data coherence between the various public faces in the multi-body modeling process of the three-dimensional geological modeling, the border stitching algorithm is proposed based on an improved butterfly subdivision strategy, and makes the different subdivision degrees of model smoothing out. The technology of view depend subdivision surface is introduced into three-dimensional geological surface model construction, and to help the establishment of three-dimensional geological structure of the LOD model. Finally, the feasibility and effectiveness of the method is verified by taking a certain city area as the studying area and carrying out experiment of the application of the method presented by this paper.
