指标说明
Chamfer / Hausdorff 类指标越低越好，反映预测 mesh 与 GT mesh 表面采样点的双向最近邻距离；Precision/Recall/F-score 越高越好，阈值是归一化 bbox diagonal 的百分比；faces/vertices 越低表示输出更轻量，但过低可能意味着细节损失；bbox、surface area、volume ratio 用于观察尺度和表面复杂度偏差；Watertight / winding / topology valid 直接衡量 mesh 是否闭合、法向拓扑是否一致，boundary edges 和 non-manifold edges 越低越好。
