"Fepa water density II"

	  A volumetric rendering depicting water density
	  around an iron transport protein embedded in a membrane.

Some artistic insight into water density in red and blue (click for full-size image). In this example transfer functions were adapted to emphasize the water within the protein which provides a pathway from the outside of E. coli to the inside. This is probably the path used for iron uptake by the bacterium.


This visualisation was done with simian on data from one of my research projects.
