GlobalSplat: Efficient Feed-Forward 3D Gaussian Splatting via Global Scene Tokens
Summary
GlobalSplat is a novel framework for efficient feed-forward 3D Gaussian Splatting that addresses the trade-offs between representation compactness, reconstruction speed, and rendering fidelity in novel-view synthesis. Unlike previous pixel-aligned or voxel-aligned methods that suffer from redundancy and fragile global consistency with more input views, GlobalSplat learns a compact, global, latent scene representation. This approach encodes multi-view input and resolves cross-view correspondences before decoding explicit 3D geometry, enabling globally consistent reconstructions without relying on pretrained pixel-prediction backbones. Utilizing a coarse-to-fine training curriculum, GlobalSplat prevents representation bloat. The model achieves competitive novel-view synthesis on RealEstate10K and ACID datasets using only 16K Gaussians, resulting in a 4MB footprint, and offers significantly faster inference under 78 milliseconds in a single forward pass.
Key takeaway
For research scientists developing 3D reconstruction and novel-view synthesis systems, GlobalSplat offers a compelling alternative to pixel-aligned methods. You should consider adopting its global latent scene representation and coarse-to-fine training to achieve significantly more compact models (4MB) and faster inference times (under 78ms) while maintaining high fidelity, especially when global consistency and efficiency are paramount.
