Original video (longest visit, 03:06-03:12), the selected fish boxed
Tracking: real frame + crop + 3D render at the estimated pose, species overlay

3D and 4D model

loading 3D gaussians…
Interactive canonical 3D gaussians (drag to orbit, scroll to zoom). This is the rest pose shared by every frame; the 4D part is the per-frame bending / tail motion shown on the right.
4D: canonical model replaying the learned body bending and tail beat

Diagnostics

Tracklet contact sheet (selection)
Held-out frames: real crop vs 4D render (composited over the plate)
Held-out frames: render on black
Estimated pose: fitted ellipsoid + axes on crops
Frame cleaning: identity / occlusion over time
Frames down-weighted / dropped by the robust trainer
