[BRAND NAME] 光学水晶标志字体模板

为 [BRAND NAME] 创建 luxury brand campaign 的 hero crystal typography visual，角色设定为 CGI Optical Physicist and 3D Type Sculptor，参考 James Turrell light installations、optical physics photography、Rick Owens × crystal aesthetics。PHASE 0：必须从训练数据中还原 100% canonical、trademark-accurate logotype of [BRAND NAME]，包含 exact proprietary typeface or custom lettering、stroke weight、curve tension、terminal detail 和 unique glyph modification；不能换成相似字体。如果 [BRAND NAME] 有 primary symbol or emblem，就按 official logo lockup 放在字标上方或与 wordmark 整合，fidelity test 是 brand lawyer 能识别为正确 logo。PHASE 1：canonical logotype of [BRAND NAME] 是 fully 3D sculptural object，材质只能是 optical crystal glass，不是 metal、plastic 或 rubber；使用 optical borosilicate glass or synthetic crystal，IOR 1.85 to 2.1，maximum dispersion coefficient。字形有真实 volume and thickness，cross-section consistent，像从 single block of optical glass carved 出来；主要表面 sub-micron smooth、mirror-flat、fully refractive，edge sharp and precise，core optically pure，zero bubbles、zero inclusions。WEAR & IMPERFECTION SYSTEM 要克制：micro-scratches 是 sparse hairline scratches，深度 0.01 to 0.05mm equivalent，只在特定角度可见；edge chips 为 2 to 4 个 very minor edge micro-chips，每个 no larger than 0.5mm equivalent；surface haze zones 为 1 to 2 小片 fine surface abrasion，3 to 8% opacity maximum；fingerprint ghosts 可选，保留 1 partial fingerprint trace，作为 faint oily interference pattern。所有瑕疵只在 surface-level，内部 crystal volume 仍 optically perfect。PHASE 2：单一 collimated light source 从 upper-left at 35° 进入，像 precision studio spot 或 filtered sunlight。光线穿过水晶字形后产生 full chromatic dispersion，遵循 Snell's law geometry；polished face 同时 reflect and refract，光谱顺序保持 red、orange、yellow、green、blue、violet。rainbow bands 起点 laser-clean，传播时逐渐 softening and widening；micro-scratch zones 产生 scattered light filaments；internal reflections 在字形内部形成 crossed and layered rainbow patterns，每个主要字形可见 3 to 5 distinct rainbow events；sharp edge 产生 thin intense white-blue luminous line，edge chips 形成 micro-flare interruptions；chromatic aberration 在所有边缘出现 red fringe 与 blue-violet fringe。PHASE 3：background 为 pure absolute black (#000000 to #050505)，no texture、no gradient、no reflected light，letters suspended in void；只有字形内部和周围有光，2 to 4cm 半径有 subtle colored haze。PHASE 4：logotype 使用 subtle nearly frontal 3/4 angle，horizontal axis 约 5 to 10°，vertical axis elevated 5 to 10°，既读作接近正面又能看到厚度和 top face；水平居中，logo occupies 60 to 70% of frame width，若有 emblem 则 full lockup visible。Aspect ratio 为 1:1 square 或 4:5 portrait，由 [BRAND NAME] lockup proportions 判断；全画面 full sharp focus，无 depth of field，400% zoom 应看到 scratch filaments、micro-chip geometry、secondary internal reflections、fingerprint interference patterns。PHASE 5：Render 使用 Octane Render with full caustics enabled；ray tracing minimum 16 bounces；dispersion 是 physically accurate wavelength-dependent IOR，覆盖 visible light range 380nm to 700nm；micro-scratches 用 actual surface geometry displacement；caustics maximum intensity；subsurface contribution minimal；anti-aliasing maximum；sampling minimum 2048 samples per pixel；no post-process glow filters、no color grading、no compositing tricks。最终感觉是 physically accurate crystal typography，every imperfection intentional，every photon accounted for。
