ANALYSING CURVED SPACETIMES WITH TENSOR SPLATS

A new visualization technique for visualizing three-dimensional symmetric positivedefinite tensor fields of rank two is described. It supports studying the spatialprojection of a spacetime metric. The rendering technique is demonstrated uponthe Schwarzschild metric of a static black hole, the Kerr metric of a rotatingblack hole in two different coordinate systems, and a numerically computed datasetdescribing the metric of two colliding black holes.
