“12 34”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. High-clarity transparent optical-glass rendering of the exact text “12 34”. The numerals are cast as thick, pure clear glass with deep internal optical depth, visible refraction and subtle liquid-pulled surface tension along corners, curves, and terminals. Preserve a clean gap between the two number groups, with strong scale and measured spatial rhythm. A pale lavender-to-ice-blue studio gradient passes through the transparent material, visibly distorted inside every numeral without adding any tint to the glass itself. Crisp white specular highlights trace thickness transitions and outer edges. Bright ray-traced caustic pools, prismatic ripples, and softly broken light bands scatter across the matte surface beneath the glass. Diffused overhead backlight travels through the numerals, producing luminous internal reflections, while a low-angle fill reveals the glass volume against the background. Minimal seamless environment, no props, no opaque treatment, no frosting, no shadows that obscure the transparent body. High-resolution product-photography finish, physically accurate optical refraction, clean negative space.
