Inspired by the paper Visualizing Interstellar's Wormhole I've made python code capable of generating wormhole visualizations.
Metric with integrated light path
Observer at the edge of the wormhole
Observer looking straight at it, with 'noise' due to integration errors.
There's also code made in C++, CUDA, where I've implemented the DOPRI5 ODE solver algorithm in a CUDA kernel in order to view the wormhole interactively in run time. Currently is in test phase.
