Renders null geodesics near a single extremally charged black hole in a Majumdar-Papapetrou spacetime, showing both the full (2+1)-dimensional spacetime trajectories and their spatial projections side by side. The time component of each geodesic is displayed along one axis, revealing how the cone structure tilts as rays approach the event horizon. Sliders control the beam direction, mass, ray count, thickness, spread, and integration length.
