Editing Vtk/Quadric (section)

==Playing With Parameters==

My desire is to generate a set of 10 concentric ellipsoidal surfaces having semi-axes of length <math>~(a_1, a_2, a_3) = (1, 3, 5)</math> using the default workflow discussed above.  In order to accomplish this and then display an interesting cut-away projection of the configuration, I have changed the (above) default parameter settings to the ones shown in the following table.  Upon execution, the resulting image that was displayed in the VisTrails spreadsheet window is presented in the panel to the right of the table.
