实验 41:A35 Mesh Face/Vertex Mask

把逐点 surface evidence 投票到 mesh faces/vertices,形成可编辑 mask 和监督信号

实验定位 正向 mask step / 尚未改拓扑

A35 把 A34 的 surface sample evidence 投票到真实 repair mesh 的 faces 和 vertices 上。方法是:每个 face centroid 找最近 5 个 surface samples 做标签多数票,再用 incident faces 的加权投票得到 vertex label。这样生成的 mask 可以被后续 mesh edit 或 generation guidance 直接使用。

结果:mask npz=2/2,face PLY=2/2,vertex PLY=2/2;mean face confidence=0.9327,mean vertex confidence=0.9835。

Voting Rule

  • face vote:face centroid 的 kNN surface sample majority,k=5。
  • vertex vote:incident face labels 按 face confidence 加权投票。
  • tie priority:conflict 优先于 improved,避免可见冲突被平均掉;unobserved 次之,neutral 最弱。
  • outputs:face_vertex_masks.npz、mesh_face_mask.ply、mesh_vertex_mask.ply、PNG projection。

Why It Matters

A35 把 VGGT observable-state evidence 从点云推进到了 mesh supervision。后续可以对 conflict faces 做回退,对 improved faces 做锁定,对 neutral/unobserved faces 做弱约束补全。这比 case-level 选择更接近论文方法。
