Split 关闭时使用原顶点采样，Cleanup 仍处理原平面区域。Depth Surface 的 Cleanup 在分离后、投影和厚度前执行；其他 Shape 保持原清理流程。

未关联选中切边的顶点使用原始 XYZ。切口顶点以 `原 XYZ × 所属侧 Z / 原 Z` 保持原相机射线，随后执行既有 Uniform Scale、Reference Depth 和 Depth Scale 投影。
|
||||
|
||||
厚度前固定顶点数据，使正背面和侧壁使用相同位置。连接时以原顶点编号和厚度层构造临时整数坐标，合并同一身份的副本后恢复场景坐标，保持近距离分离区域各自独立。实现位于 `cutout_depth_surface.py`，由 `build_cutout.py` 构建进共享节点资产。

暂存值通过 Store Named Attribute 写入保留前缀 `o_depth_`：面中心与相机采样使用 FACE，所属侧相机采样与切口标记使用 CORNER，最终相机坐标、表面位置、源顶点编号与厚度分段数使用 POINT。计算区域就近使用 Named Attribute，末尾用一个 Wildcard 模式的 Remove Named Attribute 匹配 `o_depth_*`，输出保留 UVMap 与用户属性。

### 几何节点布局
|
||||
|
||||
全部七个几何节点组使用连续横排的几何主轴。主轴可适当宽松，支线内部紧凑，同一目的的计算聚在同一侧，内部间距明显小于与其他部分的距离；独立用途可在两侧错落展开。长算式横排，末端就近汇入主轴。Join Geometry、Menu Switch、Combine XYZ 的同级独立分支末端排成一列并对齐输出端，菜单分支按输入顺序上下排列，共享上游留在公共位置。必要的向左引用直接连接。Group Input 与 Named Attribute 就近放置，全接线的简单运算可折叠，常数和域设置保持可见。
|
||||
|
||||
`geometry_layouts.py` 组织平面、外层 Cutout 和三个 Shape 的布局，`cutout_depth_surface_layout.py` 组织 Depth Surface；`node_layout.py` 统一放置局部输入、隐藏未使用输出并检查节点边界。具体规则见 [AGENTS.md](../../AGENTS.md)。布局验收包含实际节点编辑器预览，以及重排前后的运算、默认值、实际连接和几何结果比较。

|

## Context
|
||||
|
||||
动机见 proposal.md。当前 `_build_depth_surface` 投影后执行 Stretch Limit 删几何，再进入分层厚度。外层 Cutout 在 Shape 前执行 Cleanup，在 Shape 后执行 Smooth。四种 Shape 共用基础网格，节点资产通过构建脚本生成并在运行时加载。
|
||||
|
||||
最新实验采用场景 Z 差除以实际面中心距离，六个物体共用节点组。用户确认内部阈值约 `5` 时效果较好，同时观察到有厚度时侧壁与正面脱开。已有“坐标有限、面数增加、平面厚度正确”的检查不足以证明封边成功。
|
||||
|
||||
## Goals
|
||||
|
||||
分离在 Depth Surface 分支内完成；厚度生成使用拆边后的同一份边界数据。零值关闭时沿用完整原始表面的采样和投影行为。验收覆盖节点组本体和真实 Cutout 外层处理链。
|
||||
|
||||
## Decisions
|
||||
|
||||
### 1. 用实际采样跨度计算深度坡度
|
||||
|
||||
令 `Cₐ、Cᵦ` 为变形前相邻面的中心，`Zₐ、Zᵦ` 为面中心 UV 采样得到的相机 Z，`U` 为正式 Uniform Scale，`D` 为 Depth Scale：
|
||||
|
||||
```text
|
||||
g = abs(Zₐ - Zᵦ) × U × abs(D) / distance(Cₐ, Cᵦ)
|
||||
```
|
||||
|
||||
基准中心与 `U × Z` 使用一致的对象局部距离单位。复用 `common.depth.depth_uniform_scale` 和现有参考深度计算，不增加新的 Mesh Detail 数据输入。对中心距离为零的退化邻接不选边，避免除零；数值保护采用与模型尺度一致的容差。
|
||||
|
||||
选择共享边上恰有两个邻面的情况。Corners of Edge → Face of Corner → Evaluate at Index 取得邻面字段。采用 Z 而非 XYZ 距离，避免把正常横向间距计入断层；采用实际中心跨度而非期望网格长度，避免轮廓附近的小三角形在 Low 下被过大的分母抑制。
|
||||
|
||||
### 2. 使用正向的 Split 控制
|
||||
|
||||
`Split` 位于内外两层接口的 Options，替代 Stretch Limit 的位置，`FACTOR`、`SINGLE`、范围 `0–1`、默认 `0`。
|
||||
|
||||
使用简单倒数换算：对于 `s > 0`，内部阈值 `T(s) = 2.5 / s`。节点直接比较 `g × s > 2.5`，零值自然关闭，避免零点除法。
|
||||
|
||||
| Split | 内部阈值 | 含义 |
|
||||
|---|---:|---|
|
||||
| 0 | 显式关闭 | 原表面保持连接 |
|
||||
| 0.25 | 10 | 较少分离 |
|
||||
| 0.5 | 5 | 用户认可的实验强度 |
|
||||
| 0.75 | 3.333… | 更多分离 |
|
||||
| 1 | 2.5 | 最大强度 |
|
||||
|
||||
常数 `2.5` 仅用于把内部阈值 `5` 放到滑块中点。关闭分支旁路新增面采样与拆边，但仍执行 Cleanup 和原始采样投影。
|
||||
|
||||
### 3. 固定切口两侧的数据，再生成厚度
|
||||
|
||||

||||

|
||||
```
|
||||
|
||||
带局部斜坡的三角阶跃样例已复现：原厚度流程直接使用面角字段时产生 64 条开口边，改为厚度前固定顶点字段后降为零。新增面角、侧面分离和重复挤出改变了面角到顶点的平均权重，使侧壁与盖面的坐标不同。
|
||||
|
||||
实现上在拆边后、厚度前固定最终顶点投影数据及边界身份，正面、背面、各段侧壁共同引用该数据。侧壁起点必须与正面边界一致，终点必须与背面边界一致，段间共享同一边界环；不得在新增侧面域重新平均原面深度。连接按同一分离区域的边界身份完成，防止全局 Merge by Distance 把原本独立的切口重新焊接。合并容差不能用来掩盖边界坐标不一致。
|
||||
|
||||
选边字段先在 EDGE 域求值，再转换到 POINT 域标记关联顶点。仅这些顶点采用拆后所属侧的平均 Z，并以 `原 XYZ × 所属侧 Z / 原 Z` 沿原相机射线重建；其他顶点保留原 XYZ。面中心 XYZ 不直接用于替换顶点位置，以免轮廓向面中心收缩。
|
||||
|
||||
保留现有分层厚度的用户语义和分段能力，修正其中的属性传播或连接环节。先复现开裂并检查面朝向、各段挤出方向、顶点域数据和边界配对，再确定最小修改。对定向正确的流形输入，每个加厚区域必须闭合；片段之间可以分离，片段内部不能露缝。
|
||||
|
||||
连接使用拆后原顶点编号与厚度层编号作为身份。生成侧壁后，暂时将这两个整数编码成合并坐标，使 Merge by Distance 只合并相同身份的副本，随后恢复捕获的真实表面位置与厚度偏移。编号按整数商、余数拆分以保持浮点表示精确；真实场景中的近距离与重合区域不影响连接身份。
|
||||
|
||||
跨区域暂存数据使用保留前缀 `o_depth_` 的 Store Named Attribute，在消费区域用 Named Attribute 就近读取。FACE 保存原面中心与相机采样，CORNER 保存所属侧采样与切口标记，POINT 保存最终相机坐标、表面位置、源顶点编号与厚度分段数。输出前用一个 Wildcard 模式的 Remove Named Attribute 匹配 `o_depth_*`，保持 UVMap 和用户属性。
|
||||
|
||||
### 4. 接入正式资产与外层流程
|
||||
|
||||
删除 Stretch Limit 接口及其专用边长捕获、删除和松散拓扑清理节点。Depth Surface 将 Cleanup 移到 Split Edges 后、投影和厚度前，按拆后 Mesh Island 的平面面积执行既有清理阈值；避免厚度与侧壁面积影响碎片判定。外层将 Cleanup 值传入此分支，不再对 Depth Surface 提前或重复清理。Split 为零时仍对原平面区域清理。其他三种 Shape 保持原清理位置，外层 Split 仅连接 Depth Surface。
|
||||
|
||||
多个物体复用同一组资产，图片与标定由各自修改器传入。验证 Smooth 作用于已正确连接的实体，既不重新缝合不同分离区域，也不暴露侧壁接缝。运行时仍按名称加载资产。
|
||||
|
||||
### 5. 按语义组织节点布局
|
||||
|
||||
按 AGENTS.md 整理资产中全部七个几何节点组。Depth Surface 的几何主链从左到右连续排列：面采样与判别、拆边、Cleanup、投影、厚度、输出。辅助字段放在使用位置附近，通过局部 Group Input 接入；隐藏未使用输出，保留节点默认 name 与标题，不用 label 替代节点类型。
|
||||
|
||||
主轴长度由处理阶段决定，字段计算按各自算式长度横向展开，同一目的的计算聚在主轴同一侧，独立用途可在两侧错落分布。支线可以跨越多个主链步骤的横向范围，同侧支线使用不同的距离和起点，并利用附近空位收紧末端连线；必要的向左引用直接连接，允许交叉，不使用 Reroute 绕行。参照 OmooNodes 的 `O Solidfy`、`O Project`、`O Smooth` 和 `O Tube`，使用局部输入与紧凑分支；完整参数已接线的简单运算可折叠。
|
||||
|
||||
大步骤之间保留明显空白，通过节点默认标题与分支形状辨认处理阶段，不放置 String 注解。计算分支可以向主轴起点左侧展开，暂存值通过命名属性传递。
|
||||
|
||||
主轴可适当宽松，支线内部间距明显小于不同部分之间的距离，用留白表达用途分组。Depth Plane 的深度偏移与厚度权重在同一侧汇合，Depth Surface 的选边判别构成紧凑的局部计算组。Join Geometry、Menu Switch、Combine XYZ 的独立同级分支末端排成一列、输出端对齐；菜单分支按输入顺序上下排列。供多个部分使用的共享上游留在公共位置。
|
||||
|
||||
Repeat 输入与输出围住厚度循环内部节点，内部流程保持从左到右，不让区域跨越无关主链或遮挡节点。Frame 仅包裹具有完整语义的区域。接口保持 Options/Data 的业务边界及 SINGLE 结构，长度参数使用 DISTANCE，Split 使用 FACTOR。
|
||||
|
||||
布局由构建脚本确定。结构验证覆盖节点实际尺寸的非重叠、接口顺序、未使用输出隐藏和区域配对；另在 Blender 节点编辑器检查可读缩放下的主链、长线、交叉和回折。自动拓扑分层或统一网格排布不能替代视觉验收。消除可避免的交叉，共享字段通过就近输入和必要的转接组织，避免为减少节点数而拉出横跨整个图的线。
|
||||
|
||||
## Risks / Trade-offs
|
||||
|
||||
- 深度坡度也响应连续陡坡 → 使用有界控制范围，以平面、斜坡、深度阶跃共同校验阈值含义。
|
||||
- High 比 Low 捕获更多局部变化 → 用规则重采样的合成曲面检查尺度趋势，真实图片用边界位置和碎片形态比较，不以切边总数相等作为验收。
|
||||
- 小三角形放大深度噪声 → 检查退化采样跨度、低噪声样本和最大档，不擅自增加改变几何的平滑预处理。
|
||||
- 厚度侧壁开裂可能存在多个原因 → 将闭合拓扑、共享边界坐标、法线和真实渲染列为独立验证项。
|
||||
- 全局焊接或外层平滑改变切口 → 用间隔小于原焊接容差的双片段覆盖回归。
|
||||
|
||||
## Migration Plan
|
||||
|
||||
新资产移除旧输入，无旧名转发或兼容控制。替换构建脚本、验证及测试后同步节点资产和必要的节点资产说明；不重写历史 OpenSpec 变更，不构建扩展发行包。已有文件中的旧节点数据由既有资产更新流程处理，不在本变更新增文件迁移机制。

|
||||
## Why
|
||||
|
||||
Depth Surface 的 Stretch Limit 通过删几何处理深度断层，在粗网格上产生斑驳缺面。面深度拆边实验已能保留表面并分离遮挡关系，但增加厚度后侧壁与正面脱开，且目前阈值的操作方向不符合使用习惯。
|
||||
|
||||
## What Changes
|
||||
|
||||
- **BREAKING**：移除 Depth Surface 及外层 Cutout 的 Stretch Limit 接口、拉伸删几何及其松散拓扑清理分支，以 Options 中的 `Split` 替代。
|
||||
- 使用“场景 Z 差 / 置换前相邻面中心实际距离”识别需要拆开的共享边。Uniform Scale 使用现有图片标定结果，Depth Scale 参与判断。
|
||||
- `Split` 范围为 `0–1`，默认 `0` 完全关闭；越大越容易分离。中点 `0.5` 对应实验内部 Split Ratio `5`。
|
||||
- 拆边后保留面所属侧的采样数据，贯穿原 Depth Surface 投影和厚度流程；修复侧壁与正、背面连接，使有厚度的分离区域具有完整边界。
|
||||
- Depth Surface 的 Cleanup 放在 Split Edges 之后、投影和厚度之前，按拆分后的平面区域清理小碎片。
|
||||
- 多个物体共同引用资产中的节点组，通过各自修改器传入图片和标定数据；四种 Shape 继续共享基础网格。
|
||||
- 整理资产中全部七个几何节点组：主轴横排、支线双侧错落并就近汇入，必要的回接直接连接，验证 Repeat 区域的排列；将布局经验写入 AGENTS.md。

## ADDED Requirements
|
||||
|
||||
### Requirement: 分离控制替换拉伸剔除
|
||||
|
||||
系统 SHALL 在 Depth Surface 及外层 Cutout 的 Options 中以 `Split` 替代 `Stretch Limit`。Split SHALL 为范围 `0–1` 的比例输入，默认 `0`，增大时不得降低同一输入几何的切边选择强度。
|
||||
|
||||
#### Scenario: 默认关闭
|
||||
- **WHEN** 用户使用默认 Split `0`
|
||||
- **THEN** 系统不增加切边，并在 Cleanup 保留的区域上使用原 Depth Surface 采样与投影行为
|
||||
|
||||
#### Scenario: 中点与最大强度
|
||||
- **WHEN** Split 分别设为 `0.5` 和 `1`
|
||||
- **THEN** 内部深度坡度阈值分别为 `5` 和 `2.5`，且控制值不能超过 `1`；正值对应阈值为 `2.5 / Split`
|
||||
|
||||
#### Scenario: 接口替换
|
||||
- **WHEN** 用户检查新 Cutout 的 Options
|
||||
- **THEN** 可见 Split，且不存在 Stretch Limit 控制及其拉伸删几何行为
|
||||
|
||||
### Requirement: 使用相邻面深度与实际跨度选择共享边
|
||||
|
||||
系统 SHALL 以场景尺度的相邻面中心 Z 差除以变形前两面中心的实际距离作为坡度得分；场景深度 SHALL 包含图片标定的 Uniform Scale 和当前 Depth Scale 的幅度。系统 SHALL 只对恰有两个邻面的共享边执行此判断，并安全处理零跨度输入。
|
||||
|
||||
#### Scenario: 同一阈值两侧
|
||||
- **WHEN** Split 为 `0.5`，两个有效邻接的坡度得分分别为 `4` 和 `6`
|
||||
- **THEN** 得分 `4` 的边不被选中，得分 `6` 的边被选中进行分离
|
||||
|
||||
#### Scenario: 等比尺度变化
|
||||
- **WHEN** 图片几何和经标定的深度同时等比缩放且 Split 不变
|
||||
- **THEN** 相应共享边的坡度得分和选择结果保持一致
|
||||
|
||||
#### Scenario: 深度归零与退化邻接
|
||||
- **WHEN** Depth Scale 为 `0` 或邻面中心距离为零
|
||||
- **THEN** 该条件不产生新增切边，且求值不产生非有限坐标
|
||||
|
||||
### Requirement: 分离保留表面及两侧独立位置
|
||||
|
||||
系统 SHALL 通过拓扑分离保留原始表面的覆盖，使用各自所属侧的数据确定拆后位置。仅设置选边而继续使用共享 UV 的同一个深度值 SHALL NOT 被视为实现两侧分离。
|
||||
|
||||
#### Scenario: 零厚度深度阶跃
|
||||
- **WHEN** Cleanup 为零，规则网格跨越深度阶跃且 Split 选中贯通边界
|
||||
- **THEN** 原始面全部保留，两侧具有独立顶点与不同场景深度，且没有拉伸剔除造成的缺面
|
||||
|
||||
#### Scenario: 开启控制但没有切边
|
||||
- **WHEN** Split 大于零且所有共享边均未达到分离阈值
|
||||
- **THEN** 顶点投影与 Split 为零时完全一致，轮廓不因面中心平均而收缩
|
||||
|
||||
#### Scenario: 切口保持原相机射线
|
||||
- **WHEN** 某些共享边被分离
|
||||
- **THEN** 仅关联顶点使用所属侧的深度，并保持原 XYZ 的相机射线方向；其他顶点保留原采样位置
|
||||
|
||||
### Requirement: Cleanup 在拆边后生成厚度前执行
|
||||
|
||||
Depth Surface SHALL 在 Split Edges 后、投影及厚度生成前执行一次 Cleanup，按拆分后平面区域的面积使用既有清理阈值。其他 Shape SHALL 保持原 Cleanup 顺序。
|
||||
|
||||
#### Scenario: 清理拆出的碎片
|
||||
- **WHEN** 拆边生成低于 Cleanup 面积阈值的独立区域
|
||||
- **THEN** 该区域在生成厚度前被清理，其余区域随后投影并加厚
|
||||
|
||||
#### Scenario: 厚度不改变清理结果
|
||||
- **WHEN** Split、基础网格和 Cleanup 保持不变，仅调整 Thickness
|
||||
- **THEN** 被 Cleanup 保留的平面区域不变
|
||||
|
||||
#### Scenario: 关闭分离仍可清理
|
||||
- **WHEN** Split 为零且 Cleanup 为正
|
||||
- **THEN** Cleanup 对原平面区域执行一次，不因分离关闭而失效
|
||||
|
||||
### Requirement: 厚度侧壁与正背面完整连接
|
||||
|
||||
系统 SHALL 在加厚时使每个分离区域的侧壁与正面、背面及相邻厚度段共享连续边界。对定向正确的流形片状输入，各加厚区域 SHALL 形成闭合表面，不得跨区域重新焊接切口。
|
||||
|
||||
#### Scenario: 阶跃区域加厚
|
||||
- **WHEN** 对已拆开的深度阶跃区域设置正厚度
|
||||
- **THEN** 每个区域的侧壁准确连接其正背面，边界无开口、重叠但未连接的接缝或错位边界
|
||||
|
||||
#### Scenario: 分段厚度
|
||||
- **WHEN** 厚度足以生成多个侧壁段
|
||||
- **THEN** 各段相接且总厚度符合输入值，侧壁端点与对应表面边界一致
|
||||
|
||||
#### Scenario: 近距离独立区域
|

||||
|
||||
- Blender 4.5.10 LTS：三套节点资产验证脚本通过，进程正常退出。
|
||||
- 最终 Cutout 定向测试：62 项通过，进程正常退出。
|
||||
- 全量回归：649 项通过、2 项预期失败、59 项子测试通过；开发环境 bpy 在解释器退出阶段仍使进程返回 1。正式 Blender 的构建、求值及重新打开检查均正常退出。
|
||||
- 三张图片各 High/Low，Split 为 0、0.5、1，Thickness 为 0、0.02，共 36 组求值：零厚度保留全部原始面；正厚度所有面边均成对连接，无开口边或非流形边。
|
||||
- 六个物体共用正式 `O Image Cutout` 及其 Depth Surface 子组。重新打开保存文件后，图像数据有效，零厚度顶点坐标与保存前一致；Split 0.5、Thickness 0.02、Smooth Iterations 2 时仍全部闭合。
|
||||
- Blender 节点编辑器实际尺寸检查无节点重叠，Repeat 区域内无无关节点；已保存总览、面判别和 Repeat 局部预览。

## 视觉结果
|
||||
|
||||
蜘蛛与蛛丝、甲虫右侧腿和噬菌体左下交叉腿的 High/Low 对比均已保存，包含关闭、中点、最大强度和中点加厚。
|
||||
|
||||
中点能分离主要深度连接，最大强度进一步增加局部分离。High/Low 的三角形布局与深度采样不同，切口位置和碎片形状仍有差异；例如甲虫右侧末端在 High 中点已断开，Low 到最大值才断开。厚度沿各自区域形成连续侧壁，闭合结论同时由完整网格拓扑检查支持。
|
||||
|
||||
合成用例覆盖默认投影、控制阈值、规则斜坡重采样、等比缩放、零跨度、拆后清理、单段与多段厚度、重合独立区域及外层平滑。接口和依赖检查覆盖其他 Shape 不受 Split 影响。
