Rendering in Curved Spacetimes

RnD Project

13 December 2016

We have observed Einstein rings around massive objects in deep space. Interstellar also gave us a view of an accretion disk around a supernatural blackhole. But what if we had a black hole inside a small room?

We modify Kevin Beason’s smallpt to handle curved ray trajectories and generate images of the Cornell box with a Schwarzschild black hole inside it. The work was selected as poster at ACM SIGGRAPH ‘17 and also a Semi-Finalist for the ACM Student Research Competition.

Thanks to Prof. Parag Chaudhuri for his guidance.
