Getting started 快速上手
BreeZ opens straight into a playground. The wind is already blowing left to right. Tap the shape tool and draw something — anything closed becomes a solid object, anything open becomes a thin obstacle. Wind speed and direction are in the bottom right. 打开 BreeZ 就直接进入风场画布，风默认从左向右吹。 用画笔工具画点什么——封闭的形状会变成固体物体，开放的线则会作为薄障碍。 右下角可以调节风速与风向。
Switching views 切换视图
Streamlines, smoke, vorticity, pressure and velocity views all share the same running simulation. Switching between them is just a different way of looking at the same air. 流线、烟流、涡量、压力、速度这些视图共享同一个正在运行的仿真。 切换它们只是换个角度看同一团空气。
Performance & resolution 性能与分辨率
If the simulation feels heavy on an older device, drop the Performance setting from High to Balanced or Saver, or lower the grid Resolution. On newer iPhones, you can push the opposite direction for crisper field renders. 如果在老设备上跑得吃力，把性能从 高 降到 均衡 或 节能， 或者把网格分辨率调低。新机型可以反过来推高，得到更细腻的场可视化。
Importing a shape from a photo 从照片导入形状
Open the object library and pick Import from Image. There are three extraction modes: Smart (Apple Vision foreground segmentation, best for recognised subjects), Threshold (auto‑threshold + largest connected component, good for line art and silhouettes) and Tap (flood‑fill from a point you tap). The traced outline drops into the playground as a wind‑tunnel obstacle. 打开物体库，选择 从图片导入。可在三种模式间切换： 智能（Apple Vision 前景分割，适合可识别的主体）、 阈值（Otsu 自适应阈值 + 最大连通区域，适合线稿与剪影）、 点选（从你点击的点做颜色泛洪）。 提取出的轮廓会作为障碍物加入风洞。
Exporting 导出
Tap the share button. You'll see a live preview of the export, with two toggles: Show simulation data overlays the wind, angle, drag and lift readouts; Include info chin attaches a brand strip below the image. You can save a still PNG or a 5‑second video. 点击分享按钮，会看到导出预览，两个开关可控： 显示仿真数据 会附上风速、角度、阻力与升力； 包含信息底栏 会在画面下方附一条品牌信息条。 可保存 PNG 静态图或 5 秒视频。
Requirements 运行要求
- iPhone running iOS 17 or later. iPhone，iOS 17 或更新版本。
- A device that supports Metal — every iPhone made in the last decade does. 支持 Metal 的设备——近十年的 iPhone 都满足。
- Photo library access is only needed if you import a shape from an image. 仅当从图片导入形状时才需要相册访问权限。
