Example prompt: Create a photorealistic 3D product render of a sleek smart speaker with a cylindrical design featuring a fabric mesh exterior in charcoal gray and a glossy top surface with touch controls. The device is positioned at a three-quarter angle to show both the fabric texture and the top interface. The render includes an impossible cross-section view revealing the internal speaker components and technology inside, including drivers, circuit board, and acoustic chambers. The lighting uses a professional 3-point studio setup with rim lighting that accentuates the curved form and materials. The background is a clean gradient with subtle reflections beneath the product on an invisible surface. Use professional 3D rendering techniques including physically-based materials (PBR), global illumination, ambient occlusion, and precise edge definition. Render in ultra-photorealistic CGI style with perfect material physics, flawless reflections, and studio-quality lighting, suitable for product design visualization and marketing.
