 #!Rall35 A simple three-dimensional field #!N #!EC #!N #!N In this 
second example, we will import a three-dimensional field on a regular 
grid. The data describe the cloud water density in a simulation 
of a storm. #!N #!N As before, place an Import tool 
from the Import and Export Category on the canvas. Place an 
Isosurface tool from the Realization Category below Import. Place an Image 
tool from the Rendering Category below Isosurface. Connect the output of 
Import to the first input of Isosurface, and connect the output 
of Isosurface to the input of Image. #!N #!N Open the 
configuration dialog box for Import, and type in the  #!F-adobe-times-bold-r-normal--18*   name 
#!EF parameter as /opt/local/dx/samples/data/cloudwater. #!N #!N Execute. You will see an 
isosurface (constant value surface) of the cloudwater density. Not that if 
you are using the same Image tool as in the previous 
example, you may need to "reset the camera" for the new 
data set. Choose  #!F-adobe-times-bold-r-normal--18*   Reset #!EF from the  #!F-adobe-times-bold-r-normal--18*   Options #!EF 
menu of the Image window. #!N #!N Open the configuration dialog 
box for Isosurface. Notice that the default for the isovalue (the 
second input) is the data mean. Change it to the value 
0.1 by typing over the  #!F-adobe-times-bold-r-normal--18*   Value #!EF field. Execute. #!N
