• 第14号单元：烟熏玻璃——深灰色半透明，呈现出雕塑般的形态
• 15号单元：驼色人字纹羊毛——温暖的棕褐色之字形织物，所有表面均有纹理
• 第16格：珍珠母贝——带有彩虹般光泽的虹彩贝壳马赛克，曲线处闪烁着光芒

材料应用规则： 每种材料都完全包裹住物体。

• 纹理比例适合家具尺寸
• 材料对物体曲率的响应正确 光照展现了每种材料独特的表面特性。
• 逼真的渲染质量，展现材质的实际外观

技术要求：

• 所有 16 个单元格中的物体轮廓均相同
• 几何形状、相机或光照方面均无任何变化
• 细胞间仅表面物质存在差异。
• 简洁的网格布局，搭配细边框
• 专业产品可视化质量 每个单元格都可以作为独立的产品渲染图。

目的：探索家具设计中的材料运用，向客户展示同一造型如何通过不同的表面处理呈现出不同的效果。展现单一设计在织物、皮革、木材、金属、石材和装饰饰面等多种材质上的多样性。

输出：4x4无缝网格，对比同一物体上的16种材质选项。格式可直接用于演示，适用于设计评审、客户选择或3D可视化作品集。

4x4 grid of identical 3D object renders showing the same furniture piece with 16 different material applications. Each cell displays the exact same object geometry with a unique surface texture applied.

Object: Curved sculptural seating form with rounded back, cushioned seat, and four angled legs. Organic mid-century modern silhouette with smooth flowing lines, gently sloped armrests, and comfortable proportions. Single unified form without separate cushions or pillows.

Camera specifications: Fixed 3/4 front angle view, warm showroom lighting from upper-left at 45°, soft ambient fill light, identical framing across all 16 cells, subtle floor shadow beneath object, clean neutral gradient background.

Object geometry (identical in all cells):

• Same exact 3D model in every cell
• Same camera angle and distance
• Same lighting setup
• Only the surface material changes between cells

16 unique material applications (one per cell, left to right, top to bottom):

Row 1 - Soft Luxury:

• Cell 1: Midnight blue velvet - deep navy plush pile absorbing light across curved surfaces
• Cell 2: Cognac full-grain leather - warm caramel with natural grain wrapping around form
• Cell 3: Cream bouclé - chunky looped wool texture following organic contours
• Cell 4: Blush pink silk - luminous soft draping appearance with subtle sheen on curves

Row 2 - Natural Elements:

• Cell 5: Live-edge walnut wood - rich brown grain flowing across entire solid form
• Cell 6: White Carrara marble - bright polished stone with gray veins (sculptural interpretation)
• Cell 7: Natural rattan weave - honey tan woven cane pattern covering all surfaces
• Cell 8: Olive green shagreen - textured bumpy stingray pattern on elegant form

Row 3 - Metals & Industrial:

• Cell 9: Brushed brass - warm golden metal with soft directional scratches
• Cell 10: Matte black steel - powder-coated charcoal covering entire form
• Cell 11: Polished chrome - mirror-like silver reflecting environment
• Cell 12: Antique bronze - deep brown with green patina weathering

Row 4 - Statement Finishes:

• Cell 13: Emerald green lacquer - jewel tone high-gloss reflective surface
• Cell 14: Smoked glass - dark translucent gray showing form as sculptural object
• Cell 15: Camel herringbone wool - warm tan zigzag woven textile on all surfaces
• Cell 16: Mother of pearl - iridescent shell mosaic with rainbow shimmer across curves

Material application rules:

• Each material wraps entirely around the object
• Texture scale appropriate for furniture size
• Material responds correctly to object curvature
• Lighting reveals unique surface properties of each material
• Realistic rendering quality showing how material would actually appear

Technical requirements:

• Identical object silhouette in all 16 cells
• Zero variation in geometry, camera, or lighting
• Only surface material differs between cells
• Clean grid layout with thin borders
• Professional product visualization quality
• Each cell could serve as standalone product render

Purpose: Material exploration for furniture design, showing clients how the same form transforms with different surface treatments. Demonstrates versatility of single design across fabric, leather, wood, metal, stone, and decorative finishes.

Output: 4x4 seamless grid comparing 16 material options on identical object. Presentation-ready format for design review, client selection, or 3D visualization portfolio.
