Abstract
Computer-generated images of black holes are invaluable tools for science, teaching, and entertainment. Nevertheless, up until recently, real-time imagery of situations with extreme space-time curvature were not possible. The paper Interactive Black-Hole Visualization by Verbraeck and Eisemann changed this.
This work follows their line of research, building upon an adaptive grid-based rendering approach. Additionally, it includes the support of an accretion disk with realistic coloration and grid-interpolation, enables full free movement around the black hole and uses stereoscopic imagery to simulate depth. By carefully arranging the computations, a speed-up of up to 8 times over previous work was achieved for the grid generation, which enables a full real-time exploration of the black-hole space-time distortion.
