It is the process ofcreating realistic images from 3d scene descriptions and reflectance data bysolving the global illumination problem e.g. by taking into account all light pathsconnecting the light sources and the sensors and summing up their contributions.Fields of applications include scientific visualization and simulation, fast renderingof vast datasets for visual effects in movie production, or product design. Theseall have their particular, high demands on a rendering system with a wide varietyof input.This thesis explores how rendering can be made more robust for these require-ments. In particular, it is investigated how the calculation of intersections betweenlight and geometry can be made numerically robust, to guarantee that no inter-sections are missed due to inaccuracies.
