应用曼列狄斯法的三维服装模型最佳分辨率计算

三维服装模型的数据量和视觉效果是密切相关的，考虑到在线浏览模型时对数据量的限制，有必要研究它们之间的关系，从而找到模型对应的最佳分辨率以满足在线浏览对小数据量和良好视觉效果双重要求. 对扫描得到的原始三维服装模型进行简化得到一系列简化模型，提出采用几何差异和曲率分布双重评价指标来表征其视觉效果，进而量化模型数据量和视觉效果之间的关系. 提出采用曼列狄斯法来计算三维服装模型的最佳分辨率. 结果表明：采用曼列狄斯法可以稳定有效的计算三维服装模型最佳分辨率；可以简化掉三维服装模型90%的数据量而不损伤其视觉效果.

Optimal resolution of 3-D garment model based on Meredith method

The data volume of 3D garment model is closed related to its visual quality. Considering the limitation of model data in real-time rendering, it is necessary to study the relationship between them and find the best resolution which meets the demands of the real-time rendering. Simplified 3D garment models with different resolutions were obtained from the origin model. Similarity and curvature distribution were used to characterize their visual effects. The relationship between model data and their visual effects were analyzed. Meredith method was used to calculate the best resolution of 3D garment model. The results show that the best resolution of 3D garment model can be obtained effectively by Meredith method. A 90% reduction in the data volume of 3D garment model will not have a significant influence on its visual effect.
