WebGL 3D ObjectWebGL 3D 物体

Create a 3D WebGL object with real lighting and depth. Use a geometric mesh (faceted shape) with physically-based material (metalness, roughness, emissive). Light it with directional and ambient lights to reveal form and edges. Technique: real 3D geometry (not CSS transforms), dynamic lighting for highlights and shadows, subtle rotation and floating motion, and a perspective camera for depth.
