[FLASH-USERS] QuickFlash Interpolation Question

[Randy Hudson]

Sam,

After you use visit's resample operator on the pseudocolor plot, you  
can use "File -> Export database ..." to save the uniform grid -- with  
as many of your variables as you want -- to a file of any of several  
formats.

The documentation doesn't say, though, whether the resample operator  
interpolates.
