- GET /api/splat serves data/work/splat.ply; manifest reports has_splat - scene3d: lazy-load @mkkellogg/gaussian-splats-3d DropInViewer when a splat exists (rigs/anchors/paths overlay as before); point-cloud fallback intact - scripts/splat_via_modelbeast.sh: train the splat on the MODELBEAST fleet (colmap_poses -> brush_train via the mb queue) and drop it in place - docs/modelbeast-crossover.md: full crossover map (fleet compute, volumetric capture w/ CorridorKey + audio sync, per-moment splats) Verified in-browser: 32MB room splat rendered via /api/splat with overlays live.

# Train a 3DGS splat of this project's scene on the MODELBEAST fleet, and drop
|
|
# it where the viewer looks for it (data/work/splat.ply).
|
|
#
|
|
# Uses the sampled SfM frames (data/work/frames) as input: uploads them to
|
|
# MODELBEAST, runs colmap_poses + brush_train on the render farm's queue, and
|
|
# downloads the trained splat back. Requires the `mb` CLI env:
|
|
# export MB_HOST=http://100.89.131.57:8777 # M3 primary
|
|
# export MB_TOKEN=... # from MODELBEAST Settings → Users
|
|
#
|
|
# (v1 re-runs COLMAP on the farm rather than shipping our local reconstruction —
|
|
# simpler and uses the farm's known-good chain; direct dataset handoff is a
|
|
# future optimization. See docs/modelbeast-crossover.md.)
