16 different surface materials

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.

4x4 的网格，由 16 种不同的材质渲染图组成，展示同一件家具的相同几何形状。每个单元格都应用了不同的表面纹理。

物件：弧形雕塑座椅，圆润的靠背，带软垫的座面，四条倾斜的椅腿。有机的中世纪现代风格轮廓，线条流畅，扶手略微倾斜，比例舒适。一体式设计，无需单独的坐垫或靠枕。

相机规格：固定 3/4 前角视角，从左上方 45° 角照射的暖色展厅照明，柔和的环境补光，所有 16 个单元格的取景相同，物体下方有微妙的地板阴影，干净的中性渐变背景。

对象几何形状（所有单元格均相同）：
每个单元格都使用完全相同的 3D 模型。
* 相同的拍摄角度和距离
* 相同的照明设置
细胞间仅表面物质发生变化。* 只有细胞表面物质发生变化。

16 种独特的材料应用（每个单元格一种，从左到右，从上到下）：

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
