  abstract = {Nowadays computing and post processing of simulation data is often
	based on efficient hierarchical methods. While multigrid methods
	are already established standards for fast simulation codes, multiresolution
	visualization methods have only recently become an important ingredient
	of real-time interactive post processing. Both methodologies use
	local error indicators which serve as criteria where to refine the
	data representation on the physical domain. In this article we give
	an overview on different types of error measurement on nested grids
	and compare them for selected applications in 2D as well as in 3D.
	Furthermore, it is pointed out that a certain saturation of the considered
	error indicator plays an important role in multilevel visualization
	and computing on implicitly defined adaptive grids.},
