Rerun teaches robotics' favorite viewer to splat

Rerun 0.36.0 adds a GaussianSplats3D archetype, putting native splat rendering inside the viewer that robotics and computer vision teams already use to debug their data.

Why it matters: Rerun is a daily-driver tool for robotics and embodied AI work. Native splat support means gaussian splatting slots into those debugging workflows for free — no separate viewer, no export dance.

Zoom in:

  • The archetype treats each gaussian as an anisotropic 3D distribution, with scales expressed as standard deviations.
  • View-dependent color is supported via spherical harmonics up to degree 3.
  • A new EWA splatting renderer — described as deliberately simple for now — runs in the browser.
  • PLY splat files now open directly in the Rerun Viewer, and splats can be logged from the Python, Rust, and C++ SDKs.

Yes, but: The archetype is labeled unstable and may change in ways incompatible with existing data.

Two rows of photoacoustic reconstructions of a branching vascular phantom, shown for SlingBAG, for PAGS, and as the ground-truth digital phantom. The SlingBAG panels carry a mottled noise floor around the vessels; the PAGS panels are cleaner, with the vessel network closer to the crisp white tracery of the phantom

Splatting, but the light is sound and the camera is a transducer

A schematic of a scene divided into a wireframe grid of cells against black. One cell is outlined in yellow and holds a sharp green cylinder; a blurred blue slab sits behind it and a red slab in front, standing in for the frozen regions flattened into single background and foreground images

Their trick makes VRAM independent of scene size. The test scenes were too small to show it.
