Refactor geometry generation to standardize Blender object coordinates
- Unified the canonical local frame for generated geometries (Plane, Depth Plane, Relief Plane, Cutout, Depth Cutout) to align with Blender's object coordinate system, setting X as horizontal, Z as up, and +Y as depth. - Removed the `Depth Axis` parameter from `O Image Cutout` and `O Image Depth Cutout`, simplifying the geometry generation process. - Updated the depth direction defaults to use +Y instead of -Z for `O Image Relief Plane` and Depth Symmetry. - Adjusted the geometry nodes to ensure thickness, projection, and shell displacements operate along the Y-axis. - Implemented new capabilities for handling object space normals to align with the new canonical frame. - Enhanced the Depth Symmetry functionality to mirror across the canonical Y-axis and perform a final rotation to maintain the correct orientation. - Added tests to validate the new coordinate system and ensure compatibility with existing assets.

## Context
|
||||
|
||||
当前 Plane、Depth Plane、Relief Plane、Cutout 与 Depth Cutout 的生成网格沿 Image Empty 局部坐标：图片平面为 XY，图片向上为 +Y，深度向纸内为 -Z。Cutout 的 BaseShape 位于 `Z=0`，Geometry Nodes 沿 Z 做厚度、投影和对称。这个约定与 Blender 常规对象坐标不一致：Blender 对象通常 up=Z、front=-Y。
|
||||
|
||||
为了把侧视对象最终摆成“左右对称轴为 X、up 为 Z”，现有实现给 Cutout 节点加入 `Depth Axis`，把输出整体转到 +X。该参数把最终摆放轴与对称轴耦合，还要求 Object Space Normal 额外补偿，使用户在四个 Cutout 入口间看到不一致的最终方向。
|
||||
|
||||
本次变更把生成几何的 canonical local frame 统一到 Blender 对象坐标，并删除 `Depth Axis`。
|
||||
|
||||
## Goals / Non-Goals
|
||||
|
||||
**Goals:**
|
||||
|
||||
- 为所有生成几何定义并实现同一套 Blender canonical local frame。
|
||||
- 让 Cutout BaseShape、Plane、Depth Plane、Relief Plane 的未修改网格都位于 XZ 平面，`Y=0`。
|
||||
- 让 Depth Symmetry 在 canonical 坐标中沿 Y 镜像，最后绕 Z 转到 X，保持 up=Z。
|
||||
- 让 Object Space Normal 随 canonical frame 和 Depth Symmetry 最终朝向一致。
|
||||
- 删除 `O Image Cutout` 与 `O Image Depth Cutout` 的 `Depth Axis` 接口和实现。
|
||||
|
||||
**Non-Goals:**
|
||||
|
||||
- 不改变 Image Empty 自身坐标或 Blender 相机/Server 模型输出坐标。
|
||||
- 不为用户新增轴向选择项。
|
||||
- 不自动迁移用户工程中已保存的旧节点组或已生成对象。
|
||||
|
||||
## Decisions
|
||||
|
||||
### 1. 新 canonical frame 由创建阶段直接生成
|
||||
|
||||
不添加“全局坐标变换”节点，而是在 Python 建网和节点构建阶段直接按新坐标生成。
|
||||
|
||||
```text
|
||||
旧 Image Empty local → 新 canonical object local
|
||||
|
||||
X → X
|
||||
Y → Z
|
||||
-Z → +Y
|
||||
+Z → -Y
|
||||
```
|
||||
|
||||
结果：
|
||||
|
||||
```text
|
||||
X = 图片右
|
||||
Z = 图片 up
|
||||
+Y = 图片纸内 / depth
|
||||
front = -Y
|
||||
BaseShape / Plane 未修改网格位于 XZ 平面，Y=0
|
||||
```
|
||||
|
||||
备选方案是在所有 modifier 前统一旋转，但会让 BaseShape、UV、metric 和节点内部轴反复转换，且不能消除 `Depth Axis` 类补偿。直接生成更直接，符合“少就是多”。
|
||||
|
||||
### 2. 所有节点深度轴从 Z 改为 Y
|
||||
|
||||
厚度、投影、Shell、Balloon、Relief 位移和 Depth Symmetry 镜像均改为 Y 轴语义：
|
||||
|
||||
- Image Plane 的网格/立方体尺寸使用 X/Z，厚度沿 Y。
|
||||
- Depth Plane 与 Relief Plane 的投影位移沿 Y。
|
||||
- Cutout 与 Depth Cutout 的 front/back 方向由 -Y/+Y 表达。
|
||||
- `Depth Direction` 默认值从 `(0, 0, 1)` 改为 `(0, 1, 0)`。
|
||||
|
||||
### 3. Depth Symmetry 作为两阶段坐标语义
|
||||
|
||||
`O Image Cutout Symmetry` 保持“先 canonical 对称、后最终摆放”：
|
||||
|
||||
```text
|
||||
canonical step:
|
||||
mirror plane = XZ, mirror axis = +Y
|
||||
keep one Y sign, mirror to the other side
|
||||
|
||||
final step:
|
||||
rotate around Z so +Y → +X
|
||||
keep +Z as up
|
||||
```
|
||||
|
||||
该 yaw 旋转同时会把 canonical front `-Y` 变成 `-X`。这是本变更明确接受的最终朝向。
|
||||
|
||||
删除 `O Image Cutout` 与 `O Image Depth Cutout` 的 `Depth Axis`。Depth Symmetry 的最终朝向只存在于 `O Image Cutout Symmetry`。
|
||||
|
||||
### 4. Object Space Normal 使用明确的几何属性契约
|
||||
|
||||
材质仍通过 Geometry 属性把 Object Space Normal 从生成坐标转换到最终渲染坐标：
|
||||
|
||||
- canonical frame 转换进入 Object Normal 的解释路径。
|
||||
- Depth Symmetry 的 front/back 反射改为 canonical Y 反射。
|
||||
- 最终 yaw 旋转由 `O Image Cutout Symmetry` 写入最终朝向属性，材质读取同一属性。
|
||||
- 删除旧 `Depth Axis` 对应的 `CUTOUT_Z_TO_X` 补偿路径。
|
||||
|
||||
普通 Plane / Depth Plane / Relief Plane 的 Object Normal 也按新 canonical frame 验证，不再依赖 Cutout 的旧轴补偿。
|
||||
|
||||
## Risks / Trade-offs
|
||||
|
||||
- 影响面很大，几乎覆盖所有生成几何和节点资产 → 使用既有 `uv run node-group build` 与全量测试闭环；不保留兼容层。
|
||||
- BaseShape 和 Plane 世界位置可能出现符号/方向回归 → 对每个入口比较源 Image Empty 的世界 bounds 和生成网格 world-space 包围盒。
|
||||
- Object Space Normal 在渲染中的表现可能不易从网格位置直接推断 → 保留/扩展材质渲染测试，覆盖 front、back、wall 和最终朝向。
|
||||
- Depth Symmetry 最终 front 从 -Y 变为 -X，可能影响后续用户操作 → 在 spec 中明确该行为，不提供旧行为。
|
||||
- 旧 `.blend` 内嵌节点和已生成对象无法自动迁移 → 运行时继续从 `O_AnyImage.blend` 资产加载，不扫描用户工程。
|
||||
|
||||
## Migration Plan
|
||||
|
||||
1. 先在 Python 建网层实现新 canonical frame，并同步 Cutout BaseShape、Plane、Depth Plane、Relief Plane 的顶点/UV/法线。
|
||||
2. 重写 Geometry Nodes 的轴语义并删除 `Depth Axis`。
|
||||
3. 调整 Depth Symmetry 与 Object Normal 属性契约。
|
||||
4. 更新测试、`tools/nodes/check.py` 和资产构建；运行 `uv run node-group build`。
|
||||
5. 运行全量测试并检查旧 `Depth Axis`、旧轴常量与旧 world-space 方向引用。
|
||||
|
||||
回滚策略为从版本控制恢复本次变更前的源码与 `O_AnyImage.blend`，不涉及数据迁移。
|
||||
|
||||
## Open Questions
|
||||
|
||||
- 最终 yaw 旋转选择 `+Y → +X` 还是 `+Y → -X`：在实现时用一个小型 orientation test 固定，保持 front 变化方向可预测。
|
||||
- 普通 Plane / Depth Plane 的 Object Normal 转换放在材质节点内还是图片加载阶段：设计倾向保留材质属性契约，实现时按节点复杂度和测试成本选择。

|
||||
## Why
|
||||
|
||||
AnyImage 生成对象的局部坐标系仍沿用 Image Empty 的 `XY + depth -Z`，与 Blender 常规对象坐标 `up=Z`、`front=-Y` 不一致。Cutout 因此需要额外的 `Depth Axis` 来把结果转到左右轴，但没有真正解决对称轴、深度方向和 Object Space Normal 的耦合问题。
|
||||
|
||||
## What Changes
|
||||
|
||||
- 统一所有生成几何的 canonical local frame：X 为图片水平、Z 为图片 up、+Y 为图片纸内深度、front 为 -Y。
|
||||
- BaseShape 与 Plane、Depth Plane、Relief Plane、Cutout、Depth Cutout 的未修改网格统一位于 XZ 平面，`Y=0`。
|
||||
- **BREAKING**：删除 `O Image Cutout` 与 `O Image Depth Cutout` 的 `Depth Axis` 输入及最终轴向旋转逻辑。
|
||||
- `O Image Cutout Symmetry` 在 canonical 坐标中沿 Y 轴镜像，最后绕 Z 旋转使对称轴指向 +X，并保持 up=+Z。
|
||||
- Depth Symmetry 最终对象允许 front 从 -Y 改变为 -X，以换取左右对称轴为 X。
|
||||
- Object Space Normal 的生成与着色转换随新 canonical frame 和最终对称朝向同步调整。
|
||||
|
||||
