3D City

3D city modeling focuses on creating realistic, detailed virtual representations of urban environments for applications ranging from urban planning and autonomous driving simulation to gaming and AI training. Current research emphasizes the development of generative AI models, often employing diffusion models, transformers, and generative adversarial networks (GANs), to automatically generate city layouts and building structures from various data sources like OpenStreetMap (OSM) data, satellite imagery, and point clouds. These advancements are improving the realism, scalability, and controllability of 3D city generation, leading to more accurate and useful simulations for diverse applications.
