支持与使用指南
scan3d 使用 iPhone 或 iPad 的深度传感器与相机，在本机采集、计算和查看三维模型。场景建模需要后置 LiDAR；实体物品建模需要前置 TrueDepth。
- 进入场景或实体物品模式，允许相机权限。缓慢移动设备并保持相邻视野重叠。
- 点击红色按钮开始。实体物品模式也可按音量键开始，再按一次结束。
- 红色区域表示未覆盖或深度无效。结束后检查预览，再点击「计算模型」。
- 在模型库中查看、测距、裁切或导出 OBJ、PLY、STL 和 USDZ。
常见问题
贴图模糊或错位：减慢移动速度、增加稳定重叠视角并改善光照。玻璃、镜面和黑色吸光表面可能无法完整扫描。前置模式请保持物体静止，距离约 15–70 cm；配准不可靠时回到上一个角度。
模型尺寸以扫描为准，不作为精密测量依据。OBJ/PLY 使用米，STL 使用毫米。语言可从首页地球按钮选择，支持跟随系统、简体中文和 English。
扫描保存在本机。删除模型也会删除对应原始数据，请先导出需要保留的模型。

Support and getting started
scan3d uses depth sensors and cameras to capture, process and view 3D models on your device. Scene mode requires rear LiDAR. Object mode requires front TrueDepth.
- Open Scene or Object and allow camera access. Move slowly with overlapping views.
- Tap the red button to start. In Object mode, either volume button starts capture; press again to finish.
- Red areas indicate missing or invalid depth. Inspect the preview, then choose Process model.
- View, measure, crop and export OBJ, PLY, STL and USDZ models from the library.
For sharper textures, move slowly, pause briefly and use steady lighting. Glass, mirrors and dark surfaces may remain incomplete. Keep objects stationary, about 15–70 cm from the front camera. Return to a previous angle if alignment is unreliable.
Measurements depend on scan quality and are not precision measurements. OBJ and PLY use meters; STL uses millimeters. Use the globe on the home screen to select Follow System, Simplified Chinese or English.
Models stay on your device. Deleting a model removes its original scan data too. Export any models you want to keep first.
