# W-052 Status status: done_current_scope task: 相机和输入系统 OrbitControls, resize handling and mouse orbit are active in the local Three viewport. Timeline transport controls now implement first/previous/play/next/ last frame state transitions over the imported SceneIR range. Exact Blender camera basis conversion is preserved at the adapter boundary. Object/Edit mode keyboard dispatch and draggable X/Y/Z transform handles route to Main commands; additional view presets and touch gesture variants remain additive UI work.
