我们提出了一种基于大量模式的交互式四边形方法，这些方法是从艺术家手动设计的模型中学到的。将模式蒸馏成紧凑的四边形规则，并存储在数据库中。在运行时，用户绘制笔触来定义补丁和所需的边缘流，系统对数据库进行查询以提取合适的模式以拧紧草图的内饰。四边形模式是一般的，可以在控制奇异点和边缘的位置的同时应用于大型区域。我们通过一系列的现场回归学课程以及与三位专业艺术家的非正式用户研究来证明我们的算法的有效性。
We propose an interactive quadrangulation method based on a large collection of patterns that are learned from models manually designed by artists. The patterns are distilled into compact quadrangulation rules and stored in a database. At run-time, the user draws strokes to define patches and desired edge flows, and the system queries the database to extract fitting patterns to tessellate the sketches' interiors. The quadrangulation patterns are general and can be applied to tessellate large regions while controlling the positions of the singularities and the edge flow. We demonstrate the effectiveness of our algorithm through a series of live retopology sessions and an informal user study with three professional artists.
