核桃复叶形态计算机模拟研究与实现

Research and Implementation of Walnut Compound Leaf Shape Computer Simulation

植物冠层是虚拟植物的重要研究内容。叶片作为植物冠层的重要组成部分,叶片形态的模拟对于虚拟植物的研究具有非常重要的价值。核桃的叶片形态不同于其他植物的叶片,有很大的特殊性,其叶片是以复叶的形式出现,模拟有一定的难度。为此,采用椭圆同轴相交的方法实现单个叶片的模拟,再利用平移和旋转等方法实现核桃复叶形态的模拟,从而为进一步进行核桃冠层模拟及其辐射传输动态模拟奠定了基础。

Plant canopy is an important research content of the virtual plant. Leaves as an important part of the plant canopy, simulation of leaf shape has very important value for the study of virtual plants. Walnut leaf morphology differs from the leaves of other plants, there is a lot of particularity, and walnut leaf is a compound leaf form, and it is difficult to be simulated. In this paper, used the methods of elliptical axis of two ellipse intersect to simulate the shape of a single leaf, and then simulate the shape of walnut compound leaf by parallel movement, rotation and others, to lay the founda- tion for simulation of the walnut canopy and dynamic radiation transmission.
