我们提出了一种用于花卉组成的交互式建模系统，支持从初始草图到详细的三维（3D）模型的无缝转换。首先，用户快速绘制所需模型的整体外观，作为分层广告牌上二维 (2D) 笔画的集合。然后，用户参考初始草图作为指导，用详细的 3D 模型迭代地替换粗略草图。由于花卉模型由许多重复组件组成，因此系统可以帮助用户重复使用 3D 组件来简化建模过程。整个模型的全局视图始终显示在单独的窗口中，以可视化局部修改如何影响全局外观。我们的系统帮助用户做出适当的设计决策，使模型与初始设计保持一致，这在传统的自下而上的工厂建模系统中是很困难的，在传统的工厂建模系统中，全局视图只有在指定所有细节后才会出现。
We present an interactive modeling system for flower composition that supports seamless transformation from an initial sketch to a detailed three‐dimensional (3D) model. To begin, the user quickly sketches the overall appearance of the desired model as a collection of two‐dimensional (2D) strokes on hierarchical billboards. Then the user iteratively replaces the coarse sketch with a detailed 3D model referring to the initial sketch as a guide. Since a flower model consists of many repetitive components, the system helps the user to reuse 3D components to facilitate the modeling process. The global view of the entire model is always shown in a separate window to visualize how local modifications affect the global appearance. Our system helps the user make appropriate design decisions to keep the model consistent with the initial design, which is difficult in traditional bottom‐up plant modeling systems in which the global view only emerges after all of the details are specified.
