- Introduced the two-times upscale specification detailing requirements for unified output, fixed model presets, arbitrary dimensions, and consistent job behavior. - Added scenarios for existing models, repeated upscale, and handling of alpha preservation. - Created the unified depth plane specification outlining geometry modes, stable interface, and asset evaluation. - Defined scenarios for mode switching, relief and camera preservation, and validation of delivered assets.

# panorama-geometry-generation Specification
|
||
|
||
## Purpose
|
||
TBD - created by archiving change add-panorama-conversion. Update Purpose after archive.
|
||
## Requirements
|
||
### Requirement: Generate panoramic radial distance
|
||
|
||
Server SHALL 从当前 RGBA 全景生成 12 个重叠的 90 度透视视图，使用已知 FOV 恢复 MoGe2 几何并融合为横向周期的径向距离场。
|
||
|
||
#### Scenario: Continuous panorama
|
||
- **WHEN** 输入包含跨越 U=0/1 的连续表面
|
||
- **THEN** 两侧使用同一周期求解，产出有限正距离且无额外拼接断层
|
||
|
||
#### Scenario: Invalid views and cancellation
|
||
- **WHEN** 部分视图全透明或模型无有效预测
|
||
- **THEN** 利用其余有效观测完成融合，全局无有效几何时返回明确错误，并在视图与融合阶段响应取消
|
||
|
||
### Requirement: Export combined depth alpha
|
||
|
||
系统 SHALL 返回颜色文件、`depth.exr` 与 `depth.json`。深度 RGB 保存径向距离，Alpha 在导出时一次合成融合 Mask × 源 Alpha；元数据 SHALL 标明等距柱状投影、深度图尺寸和参考距离。
|
||
|
||
#### Scenario: Transparent background
|
||
- **WHEN** 源图某区域 Alpha 为零
|
||
- **THEN** 该区域深度 EXR Alpha 为零，颜色文件保留源 Alpha
|
||
|
||
#### Scenario: Fractional alpha
|
||
- **WHEN** 有效模型 Mask 为 1 且源 Alpha 为 0.5
|
||
- **THEN** 深度导出 Alpha 为 0.5，几何端直接消费该值
|
||
|
||
### Requirement: Use managed production runtime
|
||
|
||
全景生成 SHALL 使用现有模型会话、Preferences 配置和 Job 生命周期；Job 参数可序列化，Server 与 Blender 数据保持进程边界。
|
||
|
||
#### Scenario: Configured inference
|
||
- **WHEN** 用户修改模型或推理分辨率级别后发起转换
|
||
- **THEN** 新任务采用配置值，最终网格细分仍由独立 Subdivide 参数控制
