abstract = "Direct volume rendering techniques are used to visualize and
explore large scalar volumes. Transfer functions (TFs) that assign
opacity and color to scalar values are very important to display
volume features, but their specification is not trivial or
intuitive. This work presents an interactive, semi-automatic tool
to assist the user in the generation of opacity and color TFs. We
use the histogram approach proposed by Kindlmann and Durkin [9] to
reduce the scope of candidate TFs presented to the user following
the Design Galleries method [18]. The combination of these two
solutions leads to a single interactive tool that allows the user
to deal with different aspects of TF specification.",
