Voxel Video Compression Test Suite
Ten voxel video sequences at several resolutions, for measuring volumetric video codecs. Every frame is a NanoVDB file.
The suite mixes animated content with synthetic edge cases, so a codec can be checked both for typical compression ratio and for its behavior on degenerate input.

Layout
<sequence>/<resolution>/frame_00000.nvdb
<sequence>/<resolution>_nvdb/frame_00000.nvdb # BirdOrange, Breakdance1990, Chapa-Giratoria, Jumping, Rumba Dancing
Frames are numbered from frame_00000 in playback order.
Loading
from spatialstudio import splv
frame = splv.Frame.load_from_nvdb(
"car/128/frame_00000.nvdb", (0, 0, 0), (127, 127, 127)
)
print(frame.get_num_voxels())
To encode a sequence with True3D's .splv codec, pass the frames to splv.Encoder from spatialstudio.
