32万個の星を持つ渦巻銀河を飛ぶ30秒のレンダリング映像

Build a deterministic 30-second animated flight through a spiral galaxy, written as code that renders its own frames. Simulate roughly 320,000 stars with differential orbital speeds so the spiral arms stay wound, and add a core burst with polar jets and an outward shockwave that carves a cavity in the disc. Render stars as soft white-blue points around a warm glowing core on a black background, with a few cyan marker worlds and thin orbit lines. Overlay an amber sci-fi survey interface: top gauges and a target readout, a mini globe, and a scrolling telemetry log at the bottom, with labels for the main regions. Script a camera path that starts from an oblique overview, dives low along an arm, rises over the core and returns to a top-down view. Use a fixed random seed so every run produces the same galaxy, and export 1,800 frames at 60 fps into a finished video file. Done means the output plays smoothly and changing the seed gives a different galaxy.
