    v1.4.4 — Local-Viewer Default Stable

    jkaindl released this 2026-05-27 07:32:33 +00:00 | 62 commits to main since this release

    After the v1.4.2/v1.4.3 viewer hotfixes, the default target="supersplat" (remote editor at playcanvas.com) still produced an empty editor for users on modern browsers: HTTPS pages cannot fetch HTTP localhost resources (Mixed-Content blocking). The user could work around it with --with-supersplat; v1.4.4 just makes that the default.

    Changed

    • [viewer] target default flipped to "supersplat-local". When the dist is built (bash scripts/setup_supersplat.sh — already part of repo setup), autosplat process / rescue finish by starting both a local SuperSplat HTTP server and a local PLY server, opening http://127.0.0.1:3000?load=http://127.0.0.1:8765/scene.ply in the browser, and blocking until Ctrl-C. Everything is HTTP-on-localhost — no mixed-content blocking, no .ply download dialog, no manual drag-and-drop.
    • Graceful fallback when the dist is missing. If target="supersplat-local" but target/supersplat/dist/index.html doesn't exist, the viewer prints a clear console hint to run the setup script and falls back to a no-op (the existing autosplat doctor warning already covers this).

    Added

    • viewer._serve_local_and_block() — shared helper that wraps serve_supersplat_local() + browser-open + signal-handled block. Re-used by the auto-open path; cli.serve --with-supersplat keeps its inline equivalent for now.

    Tests

    • test_open_in_viewer_supersplat_local_no_browser rewritten to assert the dist-missing fallback (no browser, hint message).
    • New test_open_in_viewer_supersplat_local_opens_local_servers_when_dist_present verifies the dist-present path: fake dist with index.html, both servers start, browser receives a http://127.0.0.1:*?load=http://127.0.0.1:*/scene.ply URL, stop_event keeps the test from blocking.
    • test_load_default_config_parses_cleanly updated to expect the new default target.
    • 315 tests passing.

    Real-world validation

    First end-to-end smoke against max_strasse.MP4 — the same 5:35 drone pass that v1.2.0 left at 5/244 cameras and that v1.3.0 only rescued after a manual 4-clip cut. autosplat rescue max_strasse.MP4 produced a 2.0 GB scene.ply with 490/493 cameras registered (99.4 %) in 5 h 36 min on M5, fully automatic. Pipeline trail in the logs:

    bisection.start            duration_s=335.6
bisection.probe  clip=0    cameras_registered=120  passed=true
bisection.probe  clip=1    cameras_registered=115  passed=true
bisection.combine_start    leaves=[0, 1]
pipeline.adaptive_retry    reason="low_camera_ratio: 0.03 < 0.5"  matcher=sequential
sfm.done                   cams=490  points=368582
quality_gate.passed        ratio=0.9939  matcher=exhaustive
train.done                 duration_s=8398
pipeline.done              duration_s=20168
