土星 16K 真实感 3D模型

Overview The asset combines an optimized mesh with 16K physically accurate equirectangular textures, seamlessly mapped without polar distortion. Designed for film, games, VR, AR, and fulldome environments. Ready to import and render immediately, with all materials embedded. Includes a volumetric atmosphere for ray traced engines and, in Unity, a custom atmospheric shader that simulates sunsets using color gradients and Fresnel effects without requiring additional setup. Scientific Background This 3D representation of Saturn is based on published data for its hydrogen and helium atmosphere, ammonia haze layers, latitude banding, and the persistent north polar hexagonal storm. The physically based textures capture subtle tonal shifts across belts and zones, while the ring set reflects observed brightness, opacity, and particle distribution within the A–G rings.
