任意拓扑的且兼容NURBS曲面表示测试库

本数据集用于验证和测试三维CAD引擎中任意拓扑且兼容NURBS曲面表示功能实现，该数据集主要通过筛选网络上的公开模型获得三角网格模型，统一执行三角网格模型四边形化处理，生成相应的四边形网格产生，保存格式为obj。该数据集包含顶点数几十到万量级不等的四边形网格模型，并且含有不同数量的奇异点。

This dataset is designed to validate and test the functional implementation of arbitrary-topology NURBS surface-compatible representation in 3D CAD engines. It is primarily compiled by screening publicly accessible models from the web to obtain triangular meshes, followed by a unified quadrangulation process applied to all triangular meshes to generate corresponding quadrilateral meshes, which are stored in OBJ format. The quadrilateral mesh models in this dataset have vertex counts ranging from tens to tens of thousands, and each model contains a varying number of singular points.
