Overview

Selecting this menu item pops up a list of MeshTV operators. First highlight the plot to which you want to apply the operator, unless you have the Apply operators to all plots toggle button (located above the Operators menu beneath the Active plots list ) turned on, in which case the operator will be applied to all plots. Select the operator you wish to apply. The plot will redraw with the operator applied. Note that this menu will be grayed out (and inaccessible) until you open a file.

The dotted line at the top of the menu denotes a "tear-off" menu, which means that when you click on the dotted line, the menu will "tear off" and stay posted until you close the window or press the ESC button while the window is selected.

Available operators are Arbitrary slice , Erase , Index select , Material select , Orthogonal slice , Reflect plot , and Segment . You can remove the last applied operator, or all the operators, but you cannot remove operators in an arbitrary order.

Arbitrary slice operator

This operator takes an arbitrary slice through a 3D data set. The coordinates of the slice plane are set in the Arbitrary slice operator attributes window. You can leave the slice in 3D or map it into 2D.

Erase operator

This operator allows you to remove a region of a 3D plot. The intersection of up to 6 regions defines the region to remove.

Index select operator

The index select operator performs a logical subsetting operation on a structured mesh. By specifying a minimum index, a maximum index, and an increment for each logical dimension of the mesh, you select the zones to display.

Material selection operator

The material selection operator removes materials from a mesh so they do not appear in a plot.

Orthogonal slice operator

This operator takes an orthogonal slice through a 3D data set. The axis along which the slice is taken (x, y, or z) is set in the Orthogonal slice operator attributes window.

Reflect plot operator

This operator reflects a plot across an axis.

Segment operator

This operator allows you to display a single zone and then to interactively add or subtract neighboring zones. It works only for 3D UCD datasets.

Remove last operator

When you select this option, the last applied operator is removed, and affected plots are redrawn.

Remove all operators

When you select this option, all operators are removed, and affected plots are redrawn.
