16 种不同的表面材质

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.
