Description:

The pick command sets the options for when MeshTV's visualization window is in pick mode. This mode allows the user to get information about points by selecting points on the screen using the mouse. Node numbers (for UCD meshes), zone indices (for quad meshes), and the value of the requested variable, materials, or matspecies will be printed to the text (shell) window. (If you issue this command from the GUI, the output will go to the MeshTV Output window.) The mouse selections must be made within the current visualization window, so this command cannot be used in production mode. See the winmode command for more info on the pick mode.

Picking operates on both 2D and 3D plots, but it works differently for each. In 2D, picking provides information about the data, whereas in 3D, picking allows you to interactively select a zone. This zone can later be used by segment ( defvar ) as the seed zone. To do a pick & query for data on a 3D mesh, you must first slice the data with aslice or oslice ( defvar ) to get a 2D plot, and then do a 2D pick & query. In 3D pick, the selected zone is marked by a "+" and the zone label. Only one zone is picked at a time, and once another zone is picked, the location of the previous zone is forgotten.

In 2D, each pick location is marked with a character that corresponds to one line of output. The default color for the pick character is the foreground color (which is usually white or black), but the color can be changed via the tc option.

This command also sets options for the pickpt command, which can be used without switching to pick mode.

Examples:

pick var=d

pick var=speed, tc=white
