ParaView Object Inspector

Properties Tab

The object inspector contains controls for the data reader and for the sources and filters within ParaView. These controls are found in the Properties Tab.

  1. The Apply button causes any changes in the values of the Properties tab to take effect.
  2. The Reset button returns the modified values back to the values they were the last time the Apply button was pressed. The Reset button will not return the values back to their original default values unless the Apply button has not already been pressed.
  3. The Delete button removes the current, selected output of a reader, source, or filter. The Delete button is only enabled if the selected item is not the input to another filter.

Display Tab

Display Tab

The Display Tab controls the appearance of the output from the data reader, source, or filter for the selected view. The selected view is when the graphics window is outlined in red. Different graphics windows can have different values for the Display Tab.

  1. The View section contains either one or two controls. In a new graphics window, where a selected data set has not been added to the window, the only control visible will be a checkbox to toggle on/off the visibility of the data set in the window. Once a data set is added to the window, a second control will become visible. This second control is a button to zoom the view to the data. Once a data set has been added to graphics window, the remaining sections (color, style, etc.) will become visible.
  2. The Color section allows the user to change the color mapping of the data set.
    1. The Interpolate Colors checkbox toggles on/off the interpolation of data values across cell faces before they are mapped to colors. It is toggled on by default. If it is toggled off, ParaView lets the OpenGL determine the colors. This can result in colors that are not specified in the color map.
    2. The Map Scalars checkbox toggles on/off mapping of scalars through a lookup table.
    3. The Color by pull-down menu allows the user to choose from a list of possible data arrays to color by.
    4. The Edit Color Map button is explained in Coloring Data in ParaView section.
  3. The Style section allows the user to change the appearance of the data set.
    1. The Representation pull-down menu allows you to choose:
      • Points
      • Wireframe
      • Surface
      • Outline
      • Volume
      • Surface with Edges
    2. The Interpolation pull-down menu allows you to choose either Gourand or Flat shading.
    3. The Point Size spinbox changes the size of the points in the data set.
    4. The Line Width spinbox changes the width of lines in the data set.
    5. The Opacity spinbox changes the opacity of the data set allowing you to see through it.
  4. The Edge Style section becomes available when Surface with Edges is chosen from the Representation pull-down menu. When activated, the Set Edge Color button becomes available. This will allow you to change the color of the edges.
  5. The Lighting section allows the user to change the lighting of the data set.
    1. The Specular Intensity spinbox allows the user to change the intensity of the specular light.
    2. The Specular Focus spinbox allows the user to change the focus of the specular light.
    3. The Specular White checkbox toggles on/off specual white.
  6. The Transformation section at the bottom of the Display tab has various spinboxes to perform translations, scaling, orientation, and origin on the data.
    1. The Translate spinboxes translate the data on the X, Y, and Z axes respectively.
    2. The Scale spinboxes scale the data on the X, Y, and Z axes respectively.
    3. The Orientation spinboxes rotate the data about the X, Y, and Z axes as specified in the Origin spinboxes.
    4. The Origin spinboxes provide the origin for the data to be rotated about.

The Bar Chart View section is displayed when a bar chart (such as the output from the histogram filter). These are two sections that are unique to the Display tab when this occurs.

  1. The X Axis section controls how this axis looks.
    1. The Use Points checkbox toggles on/off the use of coordinates for the X-Axis of the bar chart. When toggled on, the Component pull-down menu. Once enabled, the user can choose when component to use (X, Y, or Z).
    2. The Array Name pull-down menu allows the user to choose from a list of possible data arrays for the bar chart.
  2. The Y Axis section controls how this axis looks. It has one pull-down menu allows the user to choose from a list of possible data arrays for the Y-Axis of the bar chart.

Information Tab

Information Tab

The Information Tab allows the user to view information about the output from the data reader, source, or filter. The information tab is broken into four to five sections. The Properties section only appears if the output comes from a data reader and is not visible when a source or filter is used for the output.

  1. The Statistics section shows the type of data, the number of cells, the number of points, and how much memory the data is using.
  2. The Data Arrays section shows which data arrays are available. This can be a useful diagnostic tool when you are reading in data. If one data array shows up as being read in, while the rest of the data arrays do not show up as being read in, that pinpoints where the error is located.
  3. The Bounds section shows the maximum and minimum values in the X, Y, and Z directions.
  4. The Time section shows if the datasets contain time information. It lists each time step and the associated time value.
