中文摘要：

数字植物是农业信息学的重要研究方向,而植物建模是数字植物的主要内容。作为植物最重要的器官,叶片的真实渲染是植物真实建模研究的关键。为此,描述了近些年来植物叶片渲染与可视化研究状况,并对单一时刻植物叶片表观渲染方法与随时间动态变化的叶片表观渲染方法分别进行了详细的介绍,同时对这两方面未来发展趋势进行了初步的探讨。

英文摘要：

Digital plant is an important research direction in Agricultural Information Science,while plant modeling is the main content of digital plant.The real rendering of foliage is a key to plant modeling study.the paper described the recent research of foliage rendering and visualization,and the rendering methods of static appearance of foliage at the specific moment and variational appearance of foliage with the change of the time,as well as the future development of this field were discussed.
