### Phase 10 — Gizmo 三軸操作器(工作量:M)
|
||||
- [x] 「⊹ 操作器」toggle — 對樹面板選取的檔案顯示 Helix `TranslateManipulator` ×3(XYZ 紅綠藍箭頭)+ `RotateManipulator` ×3(旋轉環),尺寸隨檔案 Bounds 自適應
|
||||
- [x] 操作器綁定代理 `ModelVisual3D`,拖動中代理 Transform 即時套到目標所有 BodyVisual(暫時、GPU 端);邊線暫停
|
||||
- [x] 放開滑鼠(`handledEventsToo` 捕捉)→ `Dispatcher.BeginInvoke` 延後 `TransformRoot` 烘進 B-rep、操作器歸零並移到新中心
|
||||
- [x] 換樹選取自動換目標;目標被移除自動收掉;暫時 Transform 清除用 `Identity`(非 null)
|
||||
|
||||
**驗收:** 拖 X 箭頭零件僅沿世界 X 移動(與視角無關);拖環任意角度旋轉;放開後量測/干涉與顯示位置一致
|
||||
|
||||
### Phase 11 — Gizmo always-on-top 疊圖層(工作量:M)
|
||||
- [x] 操作器移到獨立透明 `Viewport3D`(`gizmoOverlay`)疊在主視窗上 → 不在主場景,**永不被實體遮擋、永遠可抓**
|
||||
- [x] `_overlayCamera` 在主相機 `Changed` 時同步(Position/方向/FOV/near-far);同尺寸 → 投影一致、操作器精準貼合
|
||||
- [x] raw Viewport3D 空白處不吃滑鼠 → 穿透回主視窗(orbit/縮放/量測不受影響);`IsHitTestVisible` 綁 `GizmoEnabled`
|
||||
- [x] 放開事件改掛 overlay(`handledEventsToo`);`_gizmoBakePending` 防同次重複烘焙
|
||||
|
||||
**驗收:** 操作器從任何視角都浮在零件上可見可抓;開啟操作器時右鍵 orbit / 量測仍正常(穿透)
