“ahoj”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. Four massive candy-surface 3D block letters spelling "ahoj" dominating the frame, filling 70% of width. A in blazing cherry red with ultra-glossy lacquer catching upper-left key light, H in electric cobalt blue, O in vivid sunshine yellow, J in punchy lime green — each letter an independent luminous sculptural object with thick uniform extrusion depth approximately 55% of letter height. Front faces finished in hard candy-lacquer coating with natural specular highlights graduating from bright white hot-spot to deep saturated hue. Side extrusion planes rendered in noticeably darker matching hues, creating crisp face-to-depth contrast that reads as solid three-dimensional volume. Hard sharp corner edges where face meets extrusion depth — zero beveling. Long dramatic cast shadows at consistent 45-degree angle, shadow depth approximately 45% of letter height, falling across a polished plain white studio floor with faint mirror reflections picking up each letter's color. Strong directional key light from upper left, warm white beam producing natural specular rolls across the lacquer faces. Background is clean minimal white studio — all visual energy lives entirely in the letters. Slight low camera elevation, near-frontal angle.
