    • A model simplification apparatus performs: inputting a 3D geometric model; forming a surface mesh on the input geometric model and registering the surface mesh as an initial mesh; classifying the surface mesh into partial surface meshes, and calculating feature quantities of the partial surface meshes; inputting each group of mesh elements of the geometry features as reference feature shapes; searching for groups of mesh elements of similar geometry features to the reference feature shapes. Furthermore, removing group of mesh elements corresponding to the similar feature shapes from the initial mesh, and forming simplified mesh parts instead of removed similar feature shapes.
    • 模型简化装置执行:输入3D几何模型; 在输入几何模型上形成表面网格,并将表面网格注册为初始网格; 将表面网格划分为部分表面网格,并计算部分表面网格的特征量; 输入几组特征的每组网格元素作为参考特征形状; 搜索类似几何特征的网格元素组与参考特征形状。 此外,从初始网格去除对应于类似特征形状的网格元素组,并且形成简化的网格部分,而不是移除相似的特征形状。
