摘要

图1所示。给定表面网格和曲率和特征对齐的交叉场(a) LoopyCuts生成一系列场感知切割环路(b)，并使用这些环路通过对象(c)生成实体切割，将模型分解成由六边形(绿色)，棱镜(蓝色)和其他(橙色)简单块(d)组成的元网格。它通过中点细化将元网格转换为六边形网格。输出六边形网格(e,f)形状良好，与输入字段对齐良好。

LoopyCuts: practical feature-preserving block decomposition for strongly hex-dominant meshing

Fig. 1. Given a surface mesh and a curvature and feature aligned cross-field (a) LoopyCuts generates a sequence of field-aware cutting loops (b), and uses these loops to generate solid cuts through the object (c), decomposing the model into a metamesh consisting of hex (green), prism (blue) and other (orange) simple blocks (d). It converts the metamesh into a hex-mesh via midpoint refinement. The output hex-mesh (e,f) is well-shaped and well-aligned with the input field.
