| Summary: | 碩士 === 國立暨南國際大學 === 資訊工程學系 === 93 === There are two main considerations in modeling of plants: one is to preserve the accuracy of botany, the other is to render the photorealistic images of computer graphics. L-System is the mainstream method of simulating the growth of plants. The reason is that the L-System is able to simulate the botanic properties of plants by integrating with the self-developing grammars of formal language. However, grammars are written manually, it may cause many errors and is very time consuming. It is very difficult for a user with no experience to learn how to writing L-grammar.
The research purpose of this paper is to design a CAD system to help users to produce grammars easily and conveniently. We also hope that inexperienced users could use our system to get photorealistic plant images without complicated training.
There are four steps in our method. First step is finding keywords from growth description of plants. Second step section is reconstructing 3D skeleton by selecting corresponding stems among photos. Third step section is calculating quantity information from 3D skeleton. The last step is transforming quantity information into L-grammar.
