由于植物模型的复杂性，计算机图形学中常用的植物模型通常是用过程方法建立的。一个困难的问题是这些模型的用户控制：少量的参数不足以详细说明工厂的特性，而大量的参数是繁琐的操作和难以理解的。为了解决这个问题，我们提出了一种方法，用于管理参与植物模型操作的参数。具体来说，我们引入分解图作为植物结构的多尺度表示，并提出了用于设计分解图上操作的树的交互式工具。支持的操作包括浏览参数空间、编辑广义参数（标量、函数和分支系统轮廓）以及定义参数之间的依赖关系。我们通过创建盆景树模型来说明我们的方法。
Because of their complexity, plant models used in computer graphics are commonly created with procedural methods. A difficult problem is the user control of these models: a small number of parameters is insufficient to specify plant characteristics in detail, while large numbers of parameters are tedious to manipulate and difficult to comprehend. To address this problem, we propose a method for managing parameters involved in plant model manipulation. Specifically, we introduce decomposition graphs as multiscale representations of plant structures and present interactive tools for designing trees that operate on decomposition graphs. The supported operations include browsing of the parameter space, editing of generalized parameters (scalars, functions, and branching system silhouettes), and the definition of dependencies between parameters. We illustrate our method by creating models of bonsai trees.
