TTB-DVSM — interactive view synthesis on ZeroGPU

Upload images / a short orbit video → π³ pose estimation + TTB-DVSM reconstruction (one GPU call) → a time-boxed interactive viser viewer.

Models (nvidia/DVSM): uploads are reconstructed with DVSM-TTB-p8-general-960p; the gallery examples were baked with DVSM-TTB-p8-DL3DV-960p.

ZeroGPU notes

Select ZeroGPU hardware in the Space Settings (it is not set via this frontmatter). ZeroGPU forks a fresh worker per @spaces.GPU call and cannot hold a GPU permanently. The interactive viewer therefore runs inside a @spaces.GPU generator that holds the GPU for one bounded session (SESSION_SECONDS, default 180); the main process reverse-proxies /viser-proxy/* to the worker-local viser port. When the session expires the GPU is released — click "Start / Continue Live Session" to resume from the already-computed artifact.

flash-attn is not installed; dvsm/models/modules.py falls back to torch SDPA (numerically equivalent). A second-phase optimization is to add a FlashAttn-3 branch in _attn_func.

Env knobs: SESSION_SECONDS, RECON_DURATION, BENCH_WIDTHS.
