Setting Variable Ranges

The Surface Viewer does not work over continuous ranges, only at discrete points. You must specify, for the model or feature, the discrete points you want to include in the display. You can display models or features over a range of points.

There are three ways you can indicate the points to include in the display. You can specify

• A single value
• Each discrete point at which you want to evaluate the model (or feature)

• For example, if you want to display the variable x at 0, 1, 7, 30, and 50, enter the following in the appropriate edit box:

  • 0 1 7 30 50
    

• The values, in the following manner:

• minimum value:step increment:maximum value
  

• For instance, if you want to display the variable x from 0 to 50 in increments of 5, enter the following in the appropriate edit box:

  • 0:5:50
    

When you alter the variables, you can select whether you want the display to update automatically or not. You can toggle the automatic update on and off by selecting View -> Automatic Evaluation. When you want to update the display, select View -> Evaluate Now.

Before you can make a movie, ensure that all the variable values are set up in this manner. You need to specify ranges for at least three variables to make a movie. See Making Movies.
