“VN”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. "VN" rendered as monumental high-clarity optical glass, fully transparent with deep visible internal thickness and crisp refraction through each material body. The glass surface carries a restrained satin-frosted diffusion only along outer transitions, preserving clear transmission and sharp liquid-polished highlights on every edge. A pale lavender-to-cool-blue studio gradient passes visibly through the letters, bending and subtly magnifying behind their interior planes. Bright white specular lines trace thickness changes, curves, terminals, and intersections; delicate organic surface tension creates barely perceptible liquid-pulled irregularity at the glass edges. Soft directional backlight and overhead diffused light produce layered internal reflections, prismatic glints, and luminous caustic projections spreading across the matte translucent surface beneath. Surrounding space remains spare and clean, with faint blurred reflections under the glass and no additional words, icons, objects, metallic effects, color tinting, or opaque fill. High-resolution product-photography rendering, ray-traced glass refraction, physically accurate caustics, controlled soft shadows, clean studio exposure.
