Reddit 老哥用 Claude Opus 5 一个提示词做出了 AAA 雪地模拟，浏览器里直接跑，能玩法术和冲雪，效果不输小团队做几个月。
Reddit 用户仅用一个详细提示词，让 Claude Opus 5 在 9 小时内、约 400 万 tokens 内完成了一个 AAA 级雪地模拟。该模拟在浏览器单标签页中通过 WebGPU 运行，包含数百万雪粒子和带布料物理的角色。用户可使用五种水系法术在雪地中雕刻地形，足迹会推挤积雪形成垄边，弹坑随时间缓慢回填。整个过程不依赖游戏引擎或 3D 建模软件，全部由 Opus 5 编写的着色器与物理代码实现。

2. 在浏览器中运行的 AAA 级雪地物理效果 x.com/VaibhavSisinty… Vaibhav Sisinty @VaibhavSisinty Someone on Reddit just built a AAA-quality snow simulation in their browser. Using Claude Opus 5. Millions of snow particles. A character in a robe with cloth physics. Five water-based spells that carve the terrain. A snow surfing system with a wake that throws spray into sunlight. Every footstep displaces snow. Trails form berms at the edges. Trenches slowly refill over time. Spells leave permanent craters. The entire thing runs in one browser tab. WebGPU. No game engine. No 3D modeling software. Just code. He wrote one detailed prompt. Opus 5 planned the architecture, wrote the shaders, built the physics, iterated from screenshots, and documented every decision. 9 hours. ~4 million tokens. You can open it right now and walk around in it. This isn't a demo. This is the kind of thing a small studio would spend months building.
