The Source menu in the ParaView Menu Bar
contains a list of sources that can be added. When you select an item
from the list, several things will occur:
The property sheet
for the source will be displayed. On this property sheet you will see
the configurable parameters of the source.
The Selection / Navigation
Window will be displayed if it was not yet displayed already.
The source that you
are creating will be the currently active data object.
The source will not be created and displayed
until you press the Accept button, which is highlighted in red whenever
a source is first created or a parameter is changed that would require
updating. If you would like to cancel the creation of the source, press
the Delete button. To reset all the parameters back to the default values
(during creation) or to the values they had when the Accept button was
last pressed (during modification) press the Reset button.
The property sheet that is
displayed when a Sphere source is created is shown on the right. The name
Sphere1 is a unique identifier for this object, and is the name of the
underlying Tcl object created. The class indicates the type of VTK object.
The label by default will match the name of the object, but this can be
changed by typing a new label in the text entry box. This label will be
used when displaying lists of data objects in the Select menu and the
Selection / Navigation Window. A brief description of the source is given
below the label. Below the Accept, Reset, and Delete buttons are the parameters
specific to this type of source.
The Accept button is used to create the
source and to accept any future parameter changes that you make. Changing
a value such as the radius of the sphere will have no effect until the
Accept button in pressed. Note that the Accept button will turn red to
indicate that something has changed requiring the source to update. The
Reset button can be used to reset all parameters back to the values used
during the last update (or the default values if the source has not been
created). The Delete button can be used to delete this source only if
it is not used as input to a filter. If the Delete button is disabled
this indicates that a filter relies on the output of this source and therefore
this source cannot be deleted until after the filter is deleted.
The remaining sections in this chapter
of the ParaView User's Guide will
cover each of the source objects available in ParaView.
