Transfer Function design toolbox for full-color volume datasets
2017
2017 IEEE Pacific Visualization Symposium (PacificVis)
In this paper, we tackle the challenge of effective Transfer Function (TF) design for Direct Volume Rendering (DVR) of full-color datasets. ...
The applicability of our TF design toolbox is demonstrated by volume ray casting challenging full-color volume data including the visible male cryosection dataset and examples from 3D histology. ...
The Visible Human datasets are courtesy of National Library of Medicine and the Barrett's histology dataset was kindly provided by Dr. Marnix Jansen, UCLH and Barts, London, UK. ...
