RoGe: Novel View Synthesis via End-to-End Implicit Reconstruction and Generation

RoGe is a new end‑to‑end framework for novel view synthesis that jointly learns an implicit 3D scene representation and a video diffusion model. It eliminates the need for explicit 3D intermediates by querying the implicit scene with camera rays to produce geometric features that condition the diffusion model. Experiments on DL3DV show that RoGe surpasses reconstruction‑based, generation‑based, and hybrid baselines in image quality and temporal consistency, and ablations confirm the benefits of ray‑queried features and joint training.

Feedforward Novel View Synthesis for Heterogeneous Cameras

The paper introduces a feed‑forward novel view synthesis method that works across heterogeneous cameras, such as perspective, fisheye, and panoramic types. It addresses tokenization ambiguity by combining token‑center relative Camera Positional Encodings with local raymaps and a projection‑aware 2D RoPE that aligns positional reasoning across different camera projections. Experiments on ScanNet++ show improved performance over camera‑conditioned baselines and zero‑shot generalization to panoramic views.
