Athenaion

Athenaion 是一座完全用代码生成的古希腊世界：没有任何外部 3D 素材、贴图或 HDR——每一块网格、每一张纹理、每一个着色器、每一棵树、每一尊雕像、每一条瀑布都是程序化生成的。作者在 README 开篇原话：「Claude Code (Opus 5.5) built it over about 2 days to match 9 reference images, and it was rendered in 4K on an integrated laptop GPU (AMD Radeon 780M).」

世界里有什么：石灰岩峭壁上的卫城、帕特农式多立克神庙（镀金山花、雕刻三角楣、猫头鹰旗帜）、以 SDF 雕刻再网格化的巨型雅典娜像、57 条带水雾与泡沫的瀑布、泻湖与带平面反射的海、渡槽与桥梁、程序化房屋组成的城市、港口与船只、岛上圆形神庙、149,000 棵柏树 / 橄榄树 / 松树与灌木、雪山山脉与体积云——前景还有一颗倒塌的大理石头像。

数字同样惊人：约 45 小时墙钟时间里出动 55 个 subagent（最多 12 并行，约 147 agent-hours），写出约 45,000 行 JS（168 个模块），消耗约 1,100 万输出 token；最终用自研离线渲染器（抖动累积抗锯齿、AgX 色调映射、辉光与色彩分级）在集成显卡上渲染出 4K 剧照与 54 秒 4K 短片。仓库 2026-10-17 创建，5 天收获 271★，MIT 开源，完整 session prompt 与 9 张参考图都在仓库里。

Athenaion is a massive ancient Greek world built entirely in code with three.js — zero external assets: every mesh, texture, shader, tree, statue and waterfall is generated procedurally. Per the author's README, verbatim: "Claude Code (Opus 5.5) built it over about 2 days to match 9 reference images, and it was rendered in 4K on an integrated laptop GPU (AMD Radeon 780M)."

Inside: an acropolis on a limestone cliff massif, a Parthenon-style Doric temple with gilded acroteria, sculpted pediments and owl banners, colossal Athena statues sculpted as signed distance fields, 57 traced waterfalls with spray and foam, a lagoon and a sea with planar reflections, aqueducts and bridges, a city of procedural houses, a harbour with ships, a tholos on an island, 149k cypress / olive / pine trees and shrubs, snowy mountains with volumetric clouds — and a giant fallen marble head in the foreground.

The numbers behind it: ~45 h wall clock, 55 subagents (up to 12 in parallel, ~147 agent-hours), ~45k lines of JavaScript in 168 modules, ~11M output tokens — rendered offline in 4K (stills plus a 54 s 4K short film) on an integrated laptop GPU.
