RDGSplat: Render-Dedicated Geometry for Novel View Synthesis

RDGSplat is proposed, which decodes a geometry dedicated to rendering from a frozen 3D foundation model while keeping its metric predictions exact, and improves novel view synthesis for three feed-forward models of two architectures on four benchmarks, with every pretrained weight frozen.

Dyna3: VLM-Guided Training-Free 4D Reconstruction via Depth Foundation Models

The key insight is that DA3's cross-view features, though trained only for depth consistency, implicitly encode motion-discriminative signals when combined with best-match feature search across frames, which could enable much denser temporal sampling that prior methods cannot support.
