基于NURBS的植物叶片几何建模

Geometry Modeling for Plant Leaf Based on NURBS

植物叶片属于非刚性物体,形态比较复杂,对其快速准确的建模对于虚拟植物生长可视化研究具有重要意义。笔者以板蓝根叶片为例探讨了基于少量三维实测数据,结合OpenGL求值器机制和NURBS函数建立叶片几何模型,研究了叶片几何模型的建立过程。

Plant leaves with complicated forms are streamlining, and the modeling of them is important to the research of virtual plants growth. In this paper, the geometry modeling of the Isatis timctoria leaf is discussed based on NURBS and OpenGL, the process of how to show it on screen is also be explained.
