Abstract

We propose a real-time method to render high-quality images of a non-rotating black hole with an accretion disc and background stars. Our method is based on beam tracing, but uses precomputed tables to find the intersections of each curved light beam with the scene in constant time per pixel. It also uses a specific texture filtering scheme to integrate the contribution of the light sources to each beam. Our method is simple to implement and achieves high frame rates.
