PrITTI: Primitive-based Generation of Controllable and Editable 3D Semantic Urban Scenes

arXiv — cs.CVWednesday, December 3, 2025 at 5:00:00 AM
  • The introduction of PrITTI marks a significant advancement in the generation of 3D semantic urban scenes, utilizing a primitive-based approach that allows for controllable and editable representations. This method contrasts with traditional voxel-based techniques, which are often limited by resolution and editing challenges. PrITTI employs a latent diffusion model to create diverse urban scenes using vectorized object primitives and rasterized surfaces.
  • This development is crucial as it enhances the efficiency and quality of 3D scene generation, achieving state-of-the-art results with lower memory requirements and faster inference times. The ability to manipulate both object and ground levels in a structured latent space opens new avenues for urban modeling and simulation, potentially benefiting various applications in architecture, urban planning, and autonomous driving.
  • The emergence of PrITTI aligns with a broader trend in artificial intelligence focused on improving 3D reconstruction and modeling techniques. As frameworks like IC-World and DynamicVerse also explore innovative methods for visual environment synthesis, the field is witnessing a shift towards more flexible and efficient models. This evolution reflects ongoing efforts to integrate advanced machine learning techniques into practical applications, enhancing the realism and interactivity of digital environments.
