“1” is a Glass text effect 使用 FontVibe AI 创作的文字效果. 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 “1” appears as a single dominant numeral sculpted from pure high-clarity optical glass, completely transparent with no tint, frosting, opacity, or colored coating. Its material body reveals deep internal optical depth, with layered refraction and subtle lens-like distortion of the environment visible through the glass. Slight liquid-pulled surface tension softens transitions at curves, terminals, and thickness changes without altering the externally controlled glyph shape. Crisp white specular highlights track every edge and bevel, while narrow bands of concentrated light travel through the transparent volume. A clean lavender-to-pale-blue studio gradient surrounds the numeral, visible through the glass in softly warped fragments. Bright ray-traced caustic patterns scatter across the matte pale surface beneath, forming prismatic pools, fine ripples, and concentrated luminous arcs. Soft diffused backlight passes through the numeral, balanced by controlled overhead studio illumination and delicate rim light. Minimal uncluttered environment, generous negative space, photorealistic optical-glass render, precise transparency, high-resolution product-photography finish.
