Orbit-benchmark evaluation data: dl3dv_val33 and dl3dv_test33

orbit_eval_data.zip (3.39 GiB, stored uncompressed; paths relative to the repo root, so unzip -o orbit_eval_data.zip inside a checkout restores them in place) - the two 33-scene slices of the DL3DV orbit (revisit) benchmark used for every number in 09_voxel_update_f1_harm/ and 10_fusion_head_frozen_3k/:

• data/orbit_cache/dl3dv_test33/ (33 records + meta.json): reported once. The 33 DL3DV test-split videos whose cameras orbit a centre facing inward, at the train thresholds (>= 400 degrees around the centre, >= 60 % of views facing it); it contains the 8 scenes of the original benchmark (data/orbit_cache/dl3dv_test). Scene list: data/orbit_cache/test_sel_loose.json.
• data/orbit_cache/dl3dv_val33/ (33 records + meta.json): chooses configurations. 33 random qualifying DL3DV train-split orbits (seed 20261029) never used to train the voxel update heads or the fusion head (not in dl3dv_train); the base trunk may have seen these scenes as training clips. Scene list: data/orbit_cache/val_sel_33.json. (On the machine that built it, the folder links into data/orbit_cache/dl3dv_train_all/; here the files are real.)

Records (scripts/data/build_orbit_cache.py, one .pt per scene, loaded by scripts/unified/eval_long_stream.py and flc/unified/train_voxel_update.load_stream): the whole video, every 3rd frame, 256 x 256 (img_u8), cameras (c2w, K), VGGT-Omega 1B @512 depth and confidence from one joint pass over the run plus the scene's 11-frame clip, rescaled to the clip scale (depth, conf, scale_to_clip), held (every 4th frame: never written to memory, the benchmark's targets), turn (cumulative angle around the orbit centre, degrees) and loop. Test videos are uncut (up to ~110 kept frames); validation runs are cut at 160 frames.

Benchmark: the observed frames are streamed in order in 11-frame windows; after every window the memory is rendered at the held-out frames of the first orbit; all-pixel PSNR / LPIPS (holes count). --loops 2 walks the video twice (6 orbits). Commands: the READMEs of 09_voxel_update_f1_harm/ and 10_fusion_head_frozen_3k/.

Derived from DL3DV-10K (frames resized; geometry from VGGT-Omega): for use within the team under DL3DV's terms; do not redistribute. Built 2026-10-29 on the 8 x B200 machine.
