Interstellar's Black Hole

Last night I watched Interstellar for the first time. I was blown away by the amazing depiction of space, the black hole, and the worm hole in the film. It's no surprise that the film was the winner of the 2015 Oscar for Visual Effects.

It took the VFX team hundreds of hours of tedious work to produce such a stunning product. Black holes have such a strong gravity field that light literally cannot escape them, and light that is surrounding black holes is bent and distorted. Filmmakers often use a technique called ray tracing to render light and reflections in images. "Ray-tracing software makes the generally reasonable assumption that light is traveling along straight paths." Generating the proper light effect as VFX was a difficult task for the team. Eugenie von Tunzelmann, a CG supervisor at Double Negative said this about their work, "We had to write a completely new renderer." Some frames took over 100 hours to render with such complex light systems in place. However, it was all worth it in the end. The visual effects alone are worth the money to see this movie.
