4.2. Operators that Generate New Variables¶
Some of VisIt’s operators act more like expressions in that they generate new variables that can be plotted. The variable type they output does not necessarily match the variable type they accept as input. For example, the IntegralCurve operator accepts a Vector and outputs a Scalar, while the ConnectedComponents operator accepts a Mesh and outputs a Scalar.
Most of the operators that generate new variables are best applied using the operators submenu of a particular plot’s variable menu. See Figure 4.9,
It is probably best after applying an operator in this fashion to open the Operator’s attributes window to ensure good settings for your data before clicking Draw.
