Transfer functions on a logarithmic scale for volume rendering
Simeon Potts, Torsten Bert Möller · Graphics Interface · 2004
Manual opacity transfer function editing for volume rendering can be a difficult and counter-intuitive process. This paper proposes a logarithmically scaled editor, and argues that such a scale relates the height of the transfer function to the rendered intensity of a region of particular density in the volume almost directly, resulting in much improved, simpler manual transfer function editing.
