概要	This paper presents a new framework for identifying and visualizing such isosurface embeddings involved in the volume datasets. The contributions of this paper are twofold. The first contribution is an algorithm for extracting the isosurface embeddings by tracing the topological volume skeleton delineated from the given volume dataset. The second is an algorithm for emphasizing such nested inner structures using multidimensional transfer functions so that we can render each voxel separately according to its relative geometric position as well as its scalar field value. The second algorithm calculates an additional dimension for the multi-dimensional transfer functions to visualize the nested structures of the volume datasets.
