Advances in appearance modeling and photorealistic rendering of plant leaves

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.
