| Abstract: | A flower opening simulation based on key lines model is proposed. First, this model generates several petals with b-spline surfaces based on key lines. Second, a flower bud is constructed according to layers of the bud and petal numbers in each layer. Then, flower opening process is simulated with Logistic function. At last, flowers opening simulations of seven types are carried out with Web GL. The results show that, using this model, the average rendering time of these 7 flowers is 195.84 s, the minimum rendering time is only 12.23 s in gardenia flower opening simulation. Compared with Takashi's method, this model is more efficient in flower opening simulation process. |
