SceneFrom3D is a geometry-conditioned framework for generating outdoor 3D scenes from user-provided object layouts. Given coarse or fine object geometries, together with per-object appearance and geometry-adherence controls, our method synthesizes a complete 3D Gaussian Splatting scene that can be rendered and explored from arbitrary viewpoints. Existing generation pipelines are often limited to indoor or pre-defined camera settings, as constructing an effective view schedule becomes a major bottleneck for large, unstructured outdoor layouts. SceneFrom3D addresses this limitation with an automatic view-scheduling algorithm that selects anchor views, interpolation paths, and generation order directly from arbitrary outdoor geometry, enabling scalable outdoor 3D scene generation without manually specified camera trajectories.
