Abstract: Surface modeling methods have been widely used in 3D plant modeling. In this paper, the progress for plant surface modeling in recent years was reviewed. The key approaches used in plant surface modeling were classified by parametric surface modeling, implicit surface modeling, etc. The respective advantages of plant modeling corresponding to different approaches were analyzed. Some methods that could be considered in plant surface modeling in polygon based mesh modeling method were discussed as well. Finally, the combination between surface modeling method and the research of digital plant were prospected.
