SpaghettiSplats: a strict generalization of 3DGS extending splats to lines and curves
taiyasaki · x · 2026-11-11
Announcing SpaghettiSplats: treating 3D Gaussian Splatting as a convolution of a Dirac with a Gaussian kernel, the authors provide a strict generalization extending the Dirac mass to lines and curvilinear structures.
Highlights:
- Naturally recovers thin structures, rendered consistently under novel viewpoints
- The 3D convolution has a closed form, approximated with EWA, achieving frame rates similar to 3DGS-MCMC + SV8
- Geometry decoupled from convolution enables direct physics simulation on primitives
- Primitives can be subdivided anywhere without changing the rendering
Project page and arXiv paper are available.
