3D Generation

CityDreamer: Compositional Generative Model of Unbounded 3D Cities Haozhe Xie, Zhaoxi Chen, Fangzhou Hong, Ziwei Liu S-Lab, Nanyang Technological University TL;DR: CityDreamer learns to generate unbounded 3D cities from Google Earth imagery and OpenStreetMap. Abstract In recent years, extensive research has focused on 3D natural scene generation, but the domain of 3D city generation has not received as much exploration. This is due to the greater challenges posed by 3D city generation, mainly because humans are more sensitive to structural distortions in urban environments.
