重拓扑与Remesh流程 - Flowchart View

STEP 1: 输入 (Input)

• AI提取的密集网格(Marching Cubes输出)
• 问题: 不规则三角形、高价顶点(valence»6)、边长不均匀

STEP 2: 拓扑分析 (Topology Analysis)

• 检测: 非流形边、孔洞、自相交、翻转法向
• 计算: 顶点价(valence)、三角形质量指标
• 目标: 识别需要修复的拓扑缺陷

STEP 3: 修复与平滑 (Repair & Smooth)

• Laplacian平滑: v_i = (1-λ)v_i + λ·avg(neighbors)
• 频域分析: 低通滤波器 — 消除噪声但也模糊锐利特征
• Taubin平滑: 交替正负λ, 抵消收缩
• 阈值: λ=0.5, 迭代次数控制平滑程度

STEP 4: 重网格化 (Remesh)

• 边分裂: 过长的边 → 一分为二
• 边坍缩: 过短的边 → 合并(QEM度量代价)
• 边翻转: 改善valence → 向理想值6靠拢
• 切向重投影: 保持与原网格的逼近误差在阈值内

STEP 5: 质量验证 (Quality Validation)

• 三角形质量: 4√3·A/(l₁²+l₂²+l₃²) → 理想等边=1
• 顶点价: 内部理想6, 边界理想4
• 边长均匀性: 目标l_target附近高斯分布

STEP 6: 输出 (Output)

• 规范拓扑网格(四边面主导或均匀三角面)
• 保留原始形状, 改善网格质量

Clean composition with generous white space. Simple or no background. Main elements centered or positioned by content needs. Color values (#hex) and color names are rendering guidance only — do NOT display color names, hex codes, or palette labels as visible text in the image. Text should be large and prominent with handwritten-style fonts. Keep minimal, focus on keywords. Language: Chinese.
