3D Night-Sky Light-Source Simulator

A single photo of a bright light rarely settles what it was — the physical motion and brightness dynamics do. This 3D scene lets you switch a tracked point of light between the real behaviors of a steady star or planet, a tumbling satellite catching a brief sunlight flare as it crosses the sky, a slowly fading re-entering object or balloon, and erratic ball lightning, watching both the actual 3D trajectory and the resulting brightness and color-temperature readout update together. Because trajectory and light curve are rendered as one physical simulation rather than a flat chart, it mirrors how a real observer — or an analyst reviewing a video afterward — reconstructs what a claimed anomaly most likely was.
