  abstract = {In this paper, we present a multiresolution algorithm
		  which is capable to render multiple transparent isosurfaces
		  under real--time constraints. To this end, the underlying
		  3D data set is covered with a hierarchical tetrahedral
		  grid. The multiresolution extraction algorithm is based on
		  an adaptive traversal of the tetrahedral grid with the help
		  of error indicators. The display of transparent isosurfaces
		  using alpha blending requires a back--to--front rendering
		  of the isosurface triangles. This is achieved by a
		  hierarchical sorting procedure of the tetrahedra and the
		  isosurface components inside each tetrahedron. We will also
		  comment on the automated selection of suitable isovalues
		  for visualization applications. },
