“SERBIA”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 "SERBIA" dominates as high-clarity transparent optical glass, with substantial internal depth, thick polished edges, and subtle liquid-pulled tension at curves and terminals. Pure untinted glass transmits the environment through every letter, bending a pale lavender-blue atmospheric gradient into layered refractions and soft distortions. A cool white studio backlight passes through the glass body, producing bright internal highlights, crisp edge speculars, and ray-traced prism flashes where thickness changes. Below, precise caustic patterns scatter across a smooth reflective surface: overlapping pools of white light, faint blue-violet spectral fringes, and sharply focused refracted arcs. Behind the lettering, a distant low mountain silhouette and sparse river-like horizon remain extremely soft and partially obscured by luminous haze, visible only through the transparent letter interiors. Use clean gallery-scale negative space, a seamless lavender-blue background, gentle floor reflections, controlled diffusion around caustics, physically accurate optical refraction, high-resolution product-photography rendering, no opaque fill, no metallic material, no color tint within the glass.
