“Marcus”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。

Create a square, polished 3D typographic name graphic. Render the exact text “Marcus” once, spelled and cased exactly as shown, as the sole headline and central subject. Set it in massive, chunky display lettering with thick, uniform extrusion depth equal to 50–60% of letter height and crisp, unbeveled edges. Give each adjacent letter a different saturated hue: M cherry red, a electric blue, r sunshine yellow, c lime green, u hot orange, s violet. Front faces are ultra-glossy hard-candy lacquer with realistic upper-left specular highlights and color graduating toward the edges; extrusion sides are a darker shade of each letter’s own hue. Cast long, crisp shadows diagonally at 45 degrees toward the lower right, with shadow depth around 40–50% of letter height. Center the word, spanning roughly 84% of the canvas width and 55% of its height; slight low camera angle, frontal view. Use a clean, minimal white studio background and floor, with subtle floor reflections; keep all visual drama in the letters. High-contrast directional studio lighting, ray-traced reflections, sharp edges, professional 3D motion-graphics render. No other words, symbols, props, borders, gradients or clutter.
