4D Gaussian Streaming
Which Gaussians you pick as anchors barely matters: cheap samplers match the default strategy at deployment budgets, so the standard 8,192-anchor choice over-spends compute.
Overview
Streaming 4D Gaussian scenes requires choosing a subset of Gaussians as anchors. The field has settled on a default strategy and a default count of 8,192 without much pressure on either.
What we found
At the budgets that matter for deployment, cheap samplers match the default strategy, which makes the standard anchor count more compute than the result requires.
