“AM”是使用 FontVibe AI 创作的3D 立体粗体文字效果。厚重的方块大写字母带深度挤出，每个字母一种亮面糖果色，顶光让高光滚过圆润边角，彩色倒影落在地面上。

Massive chunky 3D block letters with heavyweight extruded presence — thick uniform extrusion depth of 50-60% of letter height. Front face finished in ultra-glossy lacquer, catching directional key light with natural specular reflections that graduate from bright highlight to deep saturated color — the surface quality of hard candy coating or high-gloss toy paint. Side extrusion planes in a noticeably darker shade of the same hue, creating crisp face-to-depth contrast that reads immediately as three-dimensional volume. Adjacent letters each carry a different vivid saturated color, maximizing chromatic contrast across the word — no two adjacent letters share the same hue family. Hard sharp corner edges where face meets extrusion, no beveling. Long dramatic cast shadows at consistent 45-degree angle, shadow depth approximately 40-50% of letter height. Strong directional key light from upper left. Bold, high-contrast, maximum visual impact. 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 glossy 3D extrusion, the directional lighting and the multi-color scheme. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as thick glossy extruded 3D blocks with hard candy-lacquer faces and darker extrusion sides. COLOR PRIORITY: if the font specifies its own colors, keep them; otherwise give each adjacent letter a different vivid saturated hue. The rendered text "AM" becomes a pair of massive glossy 3D letter sculptures, each with thick uniform extrusion depth at roughly 55% of letter height and razor-sharp face-to-side edges. A is saturated cherry red and M is electric cobalt blue, ensuring strict adjacent hue contrast. Their front faces use ultra-glossy candy-lacquer paint with clean specular bands, bright upper-left highlights, and rich saturated falloff across the planes; extrusion sides are deep crimson and midnight blue respectively. Strong directional key light from the upper left projects long, crisp 45-degree diagonal shadows across a seamless warm off-white studio floor. A narrow sunrise-yellow light band glows along the horizon behind the forms, reflected softly in the polished floor without adding environmental objects. Fine contact shadows ground the heavy letter volumes. Subtle mirror reflections repeat the red and blue faces beneath the text, softened by the floor finish. Clean product-render composition, frontal camera with slight low elevation, ray-traced reflections, high-contrast 3D motion-graphics finish, no additional words, no props, no texture clutter.
