Less Gaussians, Texture More: 4K Feed-Forward Textured Splatting
arXiv · 2603.25745
The Takeaway
It overcomes the quadratic primitive scaling bottleneck of 3D Gaussian Splatting by predicting compact primitives with per-primitive textures. This allows for high-fidelity 4K output without scene-specific optimization, which was previously computationally intractable.
From the abstract
Existing feed-forward 3D Gaussian Splatting methods predict pixel-aligned primitives, leading to a quadratic growth in primitive count as resolution increases. This fundamentally limits their scalability, making high-resolution synthesis such as 4K intractable. We introduce LGTM (Less Gaussians, Texture More), a feed-forward framework that overcomes this resolution scaling barrier. By predicting compact Gaussian primitives coupled with per-primitive textures, LGTM decouples geometric complexity
