《Serenissima》
一支船桨的速度，看完威尼斯的一天。

晨雾、黄金时刻、蓝调与夜色、雷雨，一程贡多拉穿过一座虚构的威尼斯运河街区，全部在浏览器里实时渲染。

这是我用 Claude Opus 5.5 做的作品 🧵

Venice, at the speed of an oar.

这是什么？

它不是关卡，也不是旅游广告，更像一部欧洲电影里的长镜头。

船从小码头出发，穿过晾着衣服的窄运河、两座小石桥，绕过广场，驶上大运河，到达有穹顶教堂、钟楼和哥特式宫殿的河口，再从另一条运河绕回。一圈约 1 公里，近 5 分钟。

1.城市

整座城由代码生成：立面用模块化构件拼装，按种子随机变化，相邻两栋楼不会重样。

水会映出楼影，船头推开尾波，桨划出涟漪，波纹碰到墙再弹回来。墙脚有潮痕和青苔，桥洞下晃着水面反上来的光。

街上有行人走动，入夜后窗户亮起暖光。

2.光、天气与声音

四种氛围：黄金时刻、蓝调时刻、夜晚、晨雾，也可以把时间拖到一天中的任意时刻。天气有晴、雾、雨，雨夜会来雷暴，闪电照亮钟楼。

声音同样由代码合成，桨声、船身拍水都和画面同步，再混入实地录音的水声、钟声、雨声和海鸥，按空间位置摆放。

3.怎么做的

技术栈：Three.js + WebGL 2，纯 HTML/JS，没有构建步骤。

我用 Claude Opus 5.5 一个阶段一个阶段地推进：城市生成、水体与光照、Blender 建模脚本、人物动作重定向、声音引擎，前后共 14 个阶段。
