# Wormhole Raytracer

Implementation of paper [Visualizing Interstellar's Wormhole](https://arxiv.org/pdf/1502.03809.pdf)\

For interactive version [https://github.com/zyddnys/wormhole-realtime](https://github.com/zyddnys/wormhole-realtime)

# Some tricks

- Only rays alone the equatorial plane is traced, special thanks to [Scott Manley](https://www.youtube.com/user/szyzyg/)

# How to use

- Change wormhole parameters (length, mass, radius) in [main.cc](main.cc):120

- Change image parameters (resolution, spp) in [main.cc](main.cc):18

- Change runge-kutta integration parameters (step size, total steps) in [WormholeODE.h](WormholeODE.h):214
