基于数据约束的黄瓜叶片参数化建模
Parameterized Geometric Modeling of Cucumber Leaf Based on Data Constrains
摘要
Abstract
A method for parameterized geometric modeling of cucumber leaf based on data constrains was presented. Firstly, the data of leaf was collected and measured, the statistics law was analyzed. Secondly, vein distribution and morphological characteristic parameters of two types of leaf margin were refined based on the law, which constrained the overall shape of leaves and described the details of leaf margin in the partition. According to the parameter values, the 3-D coordinates of contour feature points were calculated, and the 3-D grid was generated by Silhouette-axis skeleton modeling method. Finally, texture mapping was used for increasing the realism. The experimental results showed that the method could construct the 3-D model of cucumber leaf quickly and flexibly, and with good realism effect.关键词
