glass cube 3d model

A hyper-realistic 3D cube made of transparent glass, with the top surface replaced by realistic water. The water surface is calm with subtle ripples, natural refraction, accurate reflection of light, and visible surface tension slightly overflowing the cube edges. The cube has sharp edges, physically accurate refraction, caustics, global illumination, realistic water shader, and physically based materials (PBR). Cinematic studio lighting with soft shadows, photorealistic rendering, ray tracing, octane render, blender cycles style, ultra-high detail, 8K resolution, clean minimal background, professional product visualization. Avoid low quality, low poly, cartoon or stylized look, blurry image, noise, distorted geometry, unrealistic water behavior, broken reflections, lighting artifacts, text, logo, watermark, or compression artifacts.
