（其实我不确定这张图是否该发在 Pixiv 上，因为它其实算是摄影 + 3D + AI绘画的拼接画。我也不确定是否该加"AI 生成"的tag，因为按照官方规定，有AI参与就该标“AI生成”；但我实际上看到人们对这类半AI参与的、非一键生成式的作画，通常会标“AI辅助”而非“AI生成”。其次是从质量上来看，这幅画也更接近AI辅助和普通画作的整体质量而非AI生成的整体质量，所以我使用了“AI辅助”的tag。）
(Translation) 1. Yes, canonically, Firefly can survive in space just fine: https://www.youtube.com/watch?v=TQcc7ippnnU&t=340s 2. My friend, who has never read "The Three-Body Problem," saw this painting and thought the character was unleashing a powerful ultimate move… In fact, the droplet-shaped object in the center of the picture is the “Droplet” from "The Three-Body Problem II" — the only and most destructive weapon the Trisolarans used against humanity. All of its atoms are locked in place by the strong nuclear force, its temperature is at absolute zero, and its surface is perfectly smooth. (Anyone who hasn’t read "The Three-Body Problem", go read it right now!!! The best Chinese science fiction novel.) 3. When you search for the Droplet online, you’ll usually see a simple ice-cream-cone-like shape—honestly, that’s so unaesthetic! In my imagination, the Trisolaran Droplet should look like this: its tail is elegantly stretched down to molecular size, and the latter half has a negative curvature like $e^{-x}$ 4. Why is HSR a fusion of fantasy and soft sci-fi rather than leaning more towards hard sci-fi? Because in a purely hard-science-fiction worldview, the balance of power between civilizations would be utterly broken: just one Trisolaran Droplet would be enough to destroy an entire Xianzhou flagship; a fully armed soldier from an advanced civilization could fight an Emanator of the Aeons to a draw. So bringing the Droplet into the HSR setting inevitably makes you wonder—if HSR leaned more toward hard sci-fi, how would the story unfold?

1. 是的，流萤能在太空中存活：https://www.youtube.com/watch?v=TQcc7ippnnU&t=340s
2. 朋友居然没有读过《三体》，看到这幅画以为是角色在放大招……其实画面中央的巨大物体是《三体II·黑暗森林》中的「水滴」，是三体对人类使用的唯一的也是杀伤力最大的兵器，所有原子被强相互作用力钉死，温度处于绝对零度，表面绝对光滑
3. 在网上搜索水滴的时候，你通常会看到一个单调的甜筒冰淇淋的形状——实在是太不美了！在我的想象中，三体的水滴应该是这个样子的：尾部极为优美地被拉伸至分子大小，后半部分有着如同e^{-x}的负曲率
4. 为什么《崩坏：星穹铁道》是奇幻与「软科幻」的融合，而非更加地「硬科幻」？因为完完全全的硬科幻的世界观下，文明间的战斗力是相当崩坏的；三体文明的一颗水滴就足以摧毁一艘仙舟，而全副武装的高级文明普通兵能与星神令使五五开。所以把水滴拿到崩铁的世界观，实在是令人浮想联翩。
制作过程（非常简单，零基础也能跟着做）：
1. 用 Hyper3D 生成高质量的3D星空HDRI背景图：https://hyper3d.ai/omnicraft/hdri
2. 在 Blender 里捏一个水滴（旋转一个贝塞尔曲线即可）
3. 从模之屋下载流萤的官方建模：https://www.aplaybox.com/details/model/sKEfNYfXwqFn
4. 把 Hyper3D HDRI、水滴建模、流萤建模放进 Blender；捏角色动作、摆构图
5. 把（没有角色镜面反射的）水滴单独 render 出图
6. 把角色（和角色的镜面反射）单独 render 出图，然后丢进 NovelAI 中 image-to-image transform、用 inpainting 精修
7. 从 wikipedia 下载 Caldwell 30 星系的照片：https://commons.wikimedia.org/wiki/File:Caldwell_30.jpg
8. 把 Caldwell 30 的背景 + 水滴 render + 角色绘画放在 photoshop 中后期处理
9. 结束！
