We propose an out-of-core method for creating semi-regular surface representations from large input surface meshes. Our approach is based on a streaming implementation of the MAPS remesher of Lee et al. [18]. Our remeshing procedure consists of two stages. First, a simplification process is used to obtain the base domain. During simplification, we maintain the mapping information between the input and the simplified meshes. The second stage of remeshing uses the mapping information to produce samples of the output semi-regular mesh. The out-of-core operation of our method is enabled by the synchronous streaming of a simplified mesh and the mapping information stored at the original vertices. The synchronicity of two streaming buffers is maintained using a specially designed write strategy for each buffer. Experimental results demonstrate the remeshing performance of the proposed method, as well as other applications that use the created mapping between the simplified and the original surface representations.
我们提出了一种用于从大型输入曲面网格创建半规则曲面表示的核外方法。我们的方法基于Lee等人[18]的MAPS重网格化器的流式实现。我们的重网格化过程包括两个阶段。首先，使用简化过程来获得基础域。在简化过程中，我们维护输入网格和简化网格之间的映射信息。重网格化的第二阶段使用映射信息来生成输出半规则网格的样本。我们方法的核外操作通过简化网格和存储在原始顶点处的映射信息的同步流实现。使用为每个缓冲区专门设计的写入策略来保持两个流缓冲区的同步性。实验结果证明了所提出方法的重网格化性能，以及使用在简化曲面表示和原始曲面表示之间创建的映射的其他应用。
