植物表观的真实感建模是计算机图形学领域的重要研究内容,叶子作为植物最重要的器官,尤其受到广泛的关注。近年来,随着计算机硬件技术和图形算法的快速发展以及对植物叶子生理机理研究的不断深入,植物叶片表观质感建模和真实感绘制的研究取得了很多成果。植物叶片表面光学特性的采集与建模技术是其中的研究热点和难点。从植物叶片真实感质感模型的定义出发,介绍了近年来国内外在植物叶片表面质感建模和真实感绘制方面取得的最新研究进展,并给出详细的分析和总结。最后对该领域研究存在的问题和未来发展方向提出了一些看法。

Photorealistic modeling of plants appearance is an important research area in computer graphics. Plant leaves receives wide attention as the most important plant organ. Recently,by the rapid development of computer hardware and graphics algorithm and deep research in physiological structure of plant leaves,appearance modeling and photorealistic rendering of plant leaves has reached many good results. Especially,the acquisition of reflectance properties of plant leaves and appearance modeling are hot research topics. Starting from the definition of a photorealistic appearance model,we review the newest research development in plant appearance model and photorealistic rendering algorithm in China and abroad,and we analyze all kinds of algorithms. In the end,we summarize some problems in this research field and proposes an outlook and trends.
