The Iso-Value dialog box allows you to change the isovalue of an isosurface. The isosurface can be selected directly in the Names list or indirectly by selecting an object displayed on the isosurface.

To open this dialog box, click the Iso-Value... push button in the Scene Description dialog box. See Section  29.6.4 for details about using this dialog box.
