我们提出了一种用于建模树的基于叶瓣的树表示。新的表示基于这样的观察：树木的叶子细节可以抽象为规范的几何结构，称为叶纹理。我们引入了以下技术：（i）近似给定树数据的几何形状并将其编码为基于波瓣的表示，（ii）解码表示并合成在视觉上类似于输入的完全详细的树模型。编码树作为一种轻型中间表示，有利于大量树的高效存储和传输，例如树。例如，从服务器到客户端，用于城市环境中的交互式应用程序。该方法通过重建激光扫描树（以点集给出）以及重新表示现有树模型（以多边形给出）来评估。
We present a lobe-based tree representation for modeling trees. The new representation is based on the observation that the tree's foliage details can be abstracted into canonical geometry structures, termed lobe-textures. We introduce techniques to (i) approximate the geometry of given tree data and encode it into a lobe-based representation, (ii) decode the representation and synthesize a fully detailed tree model that visually resembles the input. The encoded tree serves as a light intermediate representation, which facilitates efficient storage and transmission of massive amounts of trees, e. g., from a server to clients for interactive applications in urban environments. The method is evaluated by both reconstructing laser scanned trees (given as point sets) as well as re-representing existing tree models (given as polygons).
