Interior view of a multi-black-hole spacetime with overlapping gravitational lensing from colored horizons
Renders the view from inside a Majumdar-Papapetrou spacetime with multiple extremally charged black holes. Null geodesics are integrated on the GPU using an RK4 scheme, and adaptive step sizes are set by the conformal potential gradient. Each event horizon is colored distinctly, revealing the complex apparent geometry created by overlapping gravitational lensing from multiple sources.
