Rendering Curved Spacetime in Everyday Scenes

Abstract

We present a generic and principled Monte Carlo raytracing approach to visualizing curved spacetime. In contrast to earlier work, our method can trace rays in curved spacetime while resolving usual ray-object intersections. This not only allows us to visualize complex cosmological phenomena, but also create plausible visualizations of what happens when a black hole or a wormhole appears in a more known environment, like a room with regular specular and diffuse surfaces.
