Global Illumination Computations with Hierarchical Finite Element Methods



Since the beginning of computer graphics, one of the primary
goals has been to create convincingly realistic images of three-dimensional
environments that are impossible to distinguish from photographs of the
real scene. The goal to create photo-realistic images has lead to the devel-
opment of completely new algorithms and 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 il-
lumination computations.
