Researchers have introduced CityPaint, a new framework designed to generate realistic, city-scale 3D textures using abundant 2D image data and diffusion models. This approach bypasses the need for extensive 3D training data, which is often scarce for urban environments. CityPaint integrates geometric priors with 2D diffusion models and employs a top-K camera baking strategy for iterative texture projection, along with a decoupled refinement mechanism for optimizing terrain and building textures. Experiments indicate that CityPaint produces coherent textures with fine details, outperforming existing methods in visual quality and consistency. AI
