Hierarchical Techniques for Global Illumination Computations



Since the beginning of computer graphics, one of the primary goals
has been to create convincingly realistic images of three-dimensional environments
that would be impossible to distinguish from photographs of the real scene. The
goal to create photo-realistic images has lead to the development of completely new
software techniques for dealing with the inherent geometric and optical complexity
of real world scenes. This paper gives an overview of advanced algorithms for photo-
realistic rendering and in particular discusses hierarchical techniques for global
illumination computations.
