Rendering a Gravitational Wave

This post is about rendering a gravitational wave (which may or may not be an actual thing) using a marching cubes algorithm. If anyone is wondering what a gravitational wave is I point you to the Wikipedia article. It is defined as a curvature in space and time which propagates as a wave traveling outward from the source. Whoever discovers the existence of such waves will win a Nobel Prize in Physics. In this post I’ll describe the dataset and how I went about rendering such a wave. I’ll also talk about optimizing RenderMan, in this case PRMan 15.1, when drawing 3 million transparent triangles.
