The quality of direct volume rendering is strongly influenced by the transfer function. The purpose of the transfer function is to highlight aspects of the volume data that are of interest to the user. Material boundaries are often regarded as interesting, since they reveal the shapes of objects and their spatial relations.We use a new transfer function domain that facilitates the selection of material boundaries in the volumetric data sets. Our domain enables to distinguish between both sides of the boundary. By reducing the partial volume effect on the boundary, we are able to easily assign optical properties to objects and their boundaries.
