“五十七中”是使用 FontVibe AI 创作的玻璃文字效果。透明光学玻璃大写字母折射光线，边缘高光明亮并带焦散，倒映在深色台面上，背景是青绿色极光夜空。

sculpted from high-clarity optical glass — letters cast from pure transparent glass with intense light refraction through the material body. Brilliant caustic light patterns projected below each letter. Sharp specular highlights trace the letter edges where glass thickness transitions. Slight organic surface tension gives letterforms a subtle liquid-pulled quality at terminals and curves. Deep internal optical depth visible through the glass. Purely transparent — no frosting, no color tinting, no opacity. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the optical-glass material, the refraction and the caustics. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as high-clarity transparent optical glass with intense refraction, sharp edge specular highlights and bright caustic patterns cast below. COLOR PRIORITY: keep the font's own colors if specified; otherwise pure clear glass with no tint. The rendered text “五十七中” appears as monumental high-clarity optical glass, each character formed from thick, perfectly transparent cast crystal with visible internal optical depth. The glass body bends and magnifies a pale lavender-to-ice-blue studio backdrop, creating clean lens-like distortion through enclosed counters and character intersections. Fine liquid-pulled tension is visible at stroke terminals and curved transitions, while sharply defined specular highlights travel along every change in glass thickness. A broad diffused backlight passes through the transparent characters, producing layered refraction and bright, overlapping caustic pools across a smooth pale acrylic ground plane. Tiny prismatic spectral flashes appear only at the brightest edge highlights and within the projected caustics; the glass itself remains colorless and fully transparent. Maintain generous negative space, a calm gallery-scale presentation, and crisp material separation between the clear glass, softly blurred lavender-blue background, and luminous refracted light. Ultra-clean product-photography rendering, ray-traced transmission, physically accurate dispersion, high-resolution optical details, no opaque fill, no dark backdrop, no added words or symbols.
