volseq_pathline_orbit — LIVE4D flow op

• Data kinds: volseq → rgbvideo

• Call: import fullseye as fs; fs.ledger.volseq_pathline_orbit(volseq, n_frames: 'int' = 36, n_seeds: 'int' = 200, pitch: 'float' = 25.0, size: 'int' = 256, yaw_start: 'float' = 0.0, yaw_span: 'float' = 360.0, static_alpha: 'float' = 0.03, win: 'int' = 3, pyr_levels: 'int' = 3, iters: 'int' = 5, reg: 'float' = 0.001, seed: 'int' = 0, trail_sigma: 'float' = 0.7, min_speed: 'float' = 0.1, min_intensity: 'float' = 0.3) -> 'np.ndarray' (to call the implementation directly, import live4d; live4d.volseq_pathline_orbit(volseq, n_frames: 'int' = 36, n_seeds: 'int' = 200, pitch: 'float' = 25.0, size: 'int' = 256, yaw_start: 'float' = 0.0, yaw_span: 'float' = 360.0, static_alpha: 'float' = 0.03, win: 'int' = 3, pyr_levels: 'int' = 3, iters: 'int' = 5, reg: 'float' = 0.001, seed: 'int' = 0, trail_sigma: 'float' = 0.7, min_speed: 'float' = 0.1, min_intensity: 'float' = 0.3) -> 'np.ndarray'; from the registry, opslive4d.get("volseq_pathline_orbit"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

`volseq_pathline_render の軌跡の立体を回して見る (n_frames, size, size, 3)(rgbvideo`)。

流れと軌跡は 1 回だけ計算し、視点だけを `yaw_start から yaw_span 度ぶん回す。video_write_gif` で

そのまま GIF に書ける。

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
