SpaghettiSplats: closed-form 3D convolution with EWA matches 3DGS-MCMC frame rates
taiyasaki · x · 2026-11-11
The author presents SpaghettiSplats, a 3D rendering approach where the 3D convolution has a closed form, further approximated with EWA (Elliptical Weighted Average). This allows rendering at frame rates comparable to 3DGS-MCMC + SV8.
The method also naturally recovers thin structures, keeping renders consistent under novel viewpoints—avoiding the flickering/breakage thin structures suffer from in typical 3DGS pipelines.
