A study of leaf modeling technology based on morphological features
Simulating a leafs shape is one of the most important modeling methods for plant modeling and visualization. In this paper, a modeling method is presented which is based on the morphological characteristics of leaves. According to these characteristics, the geometric feature points are selected in the leaves edge outlines firstly; then a geometric model is reconstructed by using a bi-cubic surface for the outlines of these different edges. Secondly, by applying several other modeling methods, such as lighting, texture mapping, projective transforming, rotation transforming, symmetric transforming and rendering, a leaf model is formed. Finally, through the texture mapping transforming, vein textures and leaf surfacing, the curved surface fitting processing has been done, successfully. In this paper, we consider leaves, such as camphor, ginkgo and maple, which have different shapes, as examples. In this study, it is indicated that models for the leaves with different shapes and characteristics can be constructed well, and their shape characteristics can be understood as well. This model has good controllability and high accuracy, and can produce a good realistic effective result.
