Houdini

Framestore's Superman talk details its 4D Gaussian splatting pipeline, from a 192-camera, 88-second take trained in Postshot to per-shot PLY files in Houdini.

Nodeconnector's Gaussian Splat Cleanup HDA is a free modular Houdini 22 SOP that removes duplicates, floaters, alpha noise and hue outliers, and fills holes.

TACTYC Onesplat generates a 3D Gaussian splat from a single image inside Houdini, running locally on an NVIDIA GPU and baking to native GSplat attributes.

GSOPs 3.0.0 adds Houdini 22 support, new nodes for baking Gaussian splats to mesh and volumes, NanoGS decimation, and mip-splatting import for Houdini.
