Controlling Inputs: Interactors #!N #!EC #!N #!N Using a configuration dialog 
box to specify tool inputs can be awkward, especially if the 
inputs are changed frequently or if the number of inputs is 
large. A simpler means of controlling input values makes use of 
 #!F-adobe-times-medium-i-normal--18*   interactors #!EF , which appear only in Control Panels. They 
are represented on the VPE canvas by  #!F-adobe-times-medium-i-normal--18*   stand-ins #!EF , 
or icons, selected from the category and tool palettes just as 
tools are. The output of an interactor, like that of any 
tool, can be connected to one or more inputs. #!N #!N 
For this part of Tutorial II, you will use a  #!F-adobe-times-medium-i-normal--18*   
scalar interactor stand-in #!EF to control an isosurface value. A scalar 
interactor can control any parameter that accepts a scalar value as 
input. Other types of interactor (e.g., vector, integer, string) can control 
parameters that take the corresponding type of input. #!N #!N Begin
