volseq_render_orbit — LIVE4D `render` op

• Data kinds: volseq → rgbvideo

• Call: import fullseye as fs; fs.ledger.volseq_render_orbit(volseq, n_frames: 'int' = 36, pitch: 'float' = 25.0, yaw_start: 'float' = 0.0, yaw_span: 'float' = 360.0, size: 'int' = 256, mode: 'str' = 'intensity', loops: 'int' = 1, percentile: 'float' = 99.5, floor: 'float' = 0.0, opacity_gain: 'float' = 1.0, depth_samples: 'int | None' = None, win: 'int' = 3, pyr_levels: 'int' = 3, iters: 'int' = 5, reg: 'float' = 0.001) -> 'np.ndarray' (to call the implementation directly, import live4d; live4d.volseq_render_orbit(volseq, n_frames: 'int' = 36, pitch: 'float' = 25.0, yaw_start: 'float' = 0.0, yaw_span: 'float' = 360.0, size: 'int' = 256, mode: 'str' = 'intensity', loops: 'int' = 1, percentile: 'float' = 99.5, floor: 'float' = 0.0, opacity_gain: 'float' = 1.0, depth_samples: 'int | None' = None, win: 'int' = 3, pyr_levels: 'int' = 3, iters: 'int' = 5, reg: 'float' = 0.001) -> 'np.ndarray'; from the registry, opslive4d.get("volseq_render_orbit"))

Usage

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

体積時系列を時間を進めながら視点を回して描く `(n_frames, size, size, 3)(rgbvideo`)。

フレーム i は時刻 `t = (i / n_frames) · T · loops mod T`(隣り合う体積の線形補間)の体積を、

yaw `yaw_start + yaw_span · i / n_frames から vol_render_transfer` で合成する。不透明度は明るさ

(系列全体の `percentile で正規化、floor 未満は透明)。mode="intensity"` は灰の明るさで、

`mode="speed" は隣り合うフレーム間の速さ(volseq_speed`、青 = 遅い → 赤 = 速い)で塗る。

`loops 周ぶん時間を回すと 1 周の軌道で拍動が何回も見える。video_write_gif` でそのまま GIF に。
