video_cube_orbit — VIDEOCUBE render op

• Data kinds: video → rgbvideo

• Call: import fullseye as fs; fs.ledger.video_cube_orbit(video, n_frames: 'int' = 36, pitch: 'float' = 25.0, yaw_start: 'float' = 0.0, yaw_span: 'float' = 360.0, size: 'int' = 256, sigma: 'float' = 1.0, alpha_gain: 'float' = 1.0, static_alpha: 'float' = 0.02, color: 'str' = 'time', mode: 'str' = 'motion', depth_samples: 'int | None' = None, floor: 'float' = 0.15) -> 'np.ndarray' (to call the implementation directly, import videocube; videocube.video_cube_orbit(video, n_frames: 'int' = 36, pitch: 'float' = 25.0, yaw_start: 'float' = 0.0, yaw_span: 'float' = 360.0, size: 'int' = 256, sigma: 'float' = 1.0, alpha_gain: 'float' = 1.0, static_alpha: 'float' = 0.02, color: 'str' = 'time', mode: 'str' = 'motion', depth_samples: 'int | None' = None, floor: 'float' = 0.15) -> 'np.ndarray'; from the registry, opsvideocube.get("video_cube_orbit"))

Usage

Color video rotating the cube (n_frames, size, size, 3) float [0, 1] (rgbvideo).

Uses video_spacetime_cube(mode) as opacity ("motion" = trajectories in a video, "dark" / "bright" = membranes or cells in a z stack), colours by the first axis (time / depth) with color="time" or by brightness with "intensity", and rotates yaw from yaw_start in equal steps over yaw_span degrees (pitch fixed). The exit for exhibits and Studio. video_write_gif turns it straight into a GIF.

>>> frames = video_cube_orbit(clip, n_frames=24, size=200)

>>> video_write_gif(frames, "cube.gif", fps=10)
