巧工是一座装进口袋的古代机械陈列馆:50 件中外古代机械与器物,全部以三维模型呈现;机器会自己运转,你也可以点穿外壳看内部。 【机器自己会转,不是预录动画】 每台机器按真实传动关系装配:入馆后水流驱动自行运转,立轮经锥齿轮增速带动主轴,三盘磨同时转动;曲柄牵杆往复、木扇一下下向炉膛鼓风。齿轮啮合、连杆往复、凸轮起落、刮板链循环都是运行时逐帧算出来的,不是预录动画。单指滑移是旋转视角、双指捏合是缩放,均为相机操作。 【点一下,看穿外壳】 点选任一零件:它被点亮,其余构件转为半透明,内部机构一次看清——藏在樽身的都柱、槽内循环的刮板链、仪象台顶的轮系。底部铭牌同步给出该零件的名称与作用;转速表按各件器物的额定传动比读数,纯往复件显示「次/分」而非「转/分」。 【两页解说:传动链 与 历史】 「传动链」逐件列出谁驱动谁;「历史」页写明年代、出处、背景与意义。 【形制有争议的,把争议摆出来】 木牛流马、司南、候风地动仪、水运浑天——史学界本无定说。这些器物内置多种复原假说,点标题下方的按钮即可切换对比,每一种都只是「一种可能」,不是标准答案。 【50 件器物 · 七个门类】 ・水利提水 · 动力(7):筒车、水排、桔槔、辘轳、翻车、水转翻车、高转筒车 ・粮食加工(7):水转连磨、连机碓、卧轮水磨、水碾、罗、风扇车、水转三事 ・纺织(6):纺车、水转大纺车、大纺车、缫车、斜织机、花楼机 ・天文 · 计时 · 指示(5):漏刻、简仪、记里鼓车、指南车、水运仪象台 ・世界古代(9):罗马双列水磨、希罗汽转球、阿基米德螺旋泵、安提基特拉机械、机轴擒纵、塔楼天文钟、贾扎里象钟、双缸水泵、可编程乐手 ・争议 · 多假说(4):木牛流马、司南、候风地动仪、水运浑天 ・百工器用(12):走马灯、竹蜻蜓、车船、杆秤、算盘、陀螺、手磨、欹器、被中香炉、踏轮起重机、曲辕犁、风筝 【离线 · 零权限 · 无内购】 全部内容随 App 内置,不发起任何网络请求,飞行模式下完整可用;不申请定位、相机、麦克风、照片、运动等任何系统权限;无账号、无广告、无内购、无订阅,也没有需要恢复的购买。设置里可按机型选择画质档位(自动 / 高 / 中 / 低)。 【请把它当演示,不要当考据】 巧工是机构原理的互动演示物,不是考据成果:齿数、转速、比例与构件尺寸均为便于看懂机构的演示取值,不可作为复原数据引用。历史文字带有「确证 / 较可靠 / 推定 / 争议」四档置信度标注,尚未逐条核对原书图版与博物馆实物。 【运行要求】iOS 17 及以上。iPhone 竖屏;iPad 原生支持,横竖屏全屏自适应(藏品墙按屏宽自动 2–4 列)。 问题、纠错与建议:xappfactory-feedback@hotmail.com
