*Start ParaView.
==Start ParaView== 
**On Linux and Mac, go into the ParaView directory (that you downloaded to above) and type “paraview”.
**On Windows, go to '''Start → All Programs → ParaView 5.x.x →''' and click '''ParaView'''
**On Windows XP, go to Start → All Programs → ParaView 3.x.x → and click ParaView
**On Mac, in the finder, go to the ParaView directory (in the Application directory where you installed ParaView) and click on “paraview”.
**On Linux go into the ParaView directory (where you downloaded ParaView) and type “paraview”.
 
==Startup Screen==
** The '''Startup Screen''' includes two important links. Both of these links can also be found from the '''Help''' menu. They are '''Getting Started Guide''' and '''Example Visualizations'''.

*Open can.ex2. 
**can.ex2 is one of the datasets in the training data, found on the web site under “Installing ParaView”.
**In ParaView, File → Open.  Go to can.ex2, and select it.  Click OK.
**Under the Properties tab of the Object Inspector, select all Variables
**Click Apply.


**'''Example Visualizations''' provide three finished visualizations.  You can then play around with a ParaView pipeline.

*Turn off the node variables for ACCL.  Since any variable that is selected takes up memory, and since some datasets are huge, often the user will only read in the data that is needed for a run.
==Help Menu==
**Click ACCL, turning the check box OFF.
**The '''Help''' menu looks like this:
**Apply.


*The screen should now look like this.  (The square will show up as grey, since ParaView 3.4 defaults to coloring by a solid color.)  You are looking at the bottom of the plate that the can is sitting on.

[[Image:beginning_paraview_2.png|800px]]


==Open can.ex2==
*Open can.ex2. 
**can.ex2 is one of the datasets included with ParaView in the Examples folder.
**In ParaView, '''File → Open'''.  In the upper left corner, there is a folder called Examples.  Go into this folder.  Select can.ex2.  Click OK.
**Under the '''Properties''' tab, select all '''Variables''' using the square to the left of the label Variables.
**Click '''Apply'''.


*Grab the can using the left mouse button.  Try the center button.  Try again with the right button.  Try all three again holding down the <SHFT> key.  Try with the <CTRL> key down.
*To change the display style, select the Display tab of the Object Inspector.  In the Style section find Representation, left click on the button (it probably says Surface).  Change this to Wireframe.  Then, change it to Surface with Edges.  Finally, turn it back to Surface.
*Change the variable used for color.  Under the Display tab, in the Color section, select Color by.  Change this to Displacement (Point DISPL).  Everything should go red.


*Note that you can do the same thing using the Active Variable and Representation toolbars.  The Active Variable toolbar also holds the Color Legend Visibility button, the vertical rainbow bar to the left.  Select the Color Legend Visibility button.


*Turn off the node variables for ACCL.  Since any variable that is selected takes up memory, and since some datasets are huge, often the user will only read in the data that is needed for a run.
**Click '''ACCL''', turning the check box OFF.
**'''Apply'''.


[[Image:beginning_paraview_3.png]]
*The screen should now look like this.  (The square will show up as red, since ParaView defaults to coloring by block, and the block we are seeing is red.)  You are looking at the bottom of the plate that the can is sitting on.


   
   
*Animate the can one frame.  Right above the window of the can are animation controls.  Click the right arrow with a bar to its left once.  The plate stays red.

[[Image:beginning_paraview_4.png]]
*Lets move the 3d object.  Grab the can using the '''left''' mouse button.  Try the '''center''' button.  Try again with the '''right''' button.  Try all three again holding down the '''<SHFT>''' key. Try again holding down the X, Y and Z keys.
*Place your mouse on a corner of the can. Now, hold the '''<CTRL>''' key down, and move the mouse up and down.  You can zoom into and out of that location.
 
*Now the screen looks like this:
 
[[Image:beginning_paraview_2BNew.jpg|1000px]]


*Notice that the can dataset is being painted in two colors -


**WHAT IS HAPPENING:  The ex2 dataset has displacement information in it.  We are actually running the plate into the can, and the whole object is moving.
*To change the representation, change '''Surface''' to '''Wireframe''' (right below '''Help''').  Then, change it to '''Surface with Edges'''.  Finally, turn it back to '''Surface'''.
**TIP: Our color map is not set correctly, for two reasons.   
***It needs to be set over the whole range of displacement, so that it grades from blue to red.
***Since we have not animated through all time steps, ParaView doesn’t know the range of displacements that it needs to deal with.  The next few steps will demonstrate this.  This ONLY works if you have NOT run through the full animation yet.
***WARNING: Very, very large data can take a long time to process.  Don’t animate your data unless you have to with very large datasets.
**Click the Rescale to Data Range color button.  The slab turns red, and the can turns blue.  We have reset our color range using the second frame of the animation.  Note that the Rescale to Data Range can be found as a button in the Active Variable Controls toolbar.


   
*Change the variable used for color.  Change this from '''Solid Color''' to Displacement (Point '''DISPL''').  (This is found just below the '''Sources''' menu.) Everything should go blue.

**Click the single right arrow, running to the end of the simulation.
**Click the “Rescale to Data Range”.
**Rewind using the furthest left arrow, then click the single right arrow again.
*Check Information.  Click on the Information tab of the Object Inspector.  This tells us that we have an unstructured grid, the number of cells, the number of points, and the amount of memory used.  It also tells us what type of data we have, and the ranges for this data.  We also see the time in each time step.
*Move the object to the left (using the middle mouse button).  Zoom in on the object (using the right mouse button).  Then, click the Reset icon.    Select the +X icon, the –X icon, etc.
   
   
*Rotate the can again so you can see it.  Select the menu option Filters → Common → Clip.  Press Apply.  Animate the object with the right arrow button found above the drawing window.  Reset the animation.  Uncheck the Show Plane checkbox, located under Properties to the left.  Play the animation once again.
*Animate the can one frame.  Right above the window of the can are animation controls.  Click the right arrow with a bar to its left once.  The plate turns red.

Introduction

This tutorial will describe how to start ParaView, find information and help about ParaView, and describe some of the more important controls used by ParaView.

The ParaView web site is located at http://www.paraview.org. New versions of ParaView can be found here, along with different tutorials and advice. ParaView versions include 32 and 64 bit versions of Linux, Windows and Mac OS X. Training (practice) data is also found on the paraview.org website. These tutorials are found here: http://www.paraview.org/Wiki/SNL_ParaView_4_Tutorials

ParaView now has an integrated help. It is found under the menu item Help→ Help.

A simple example

Start ParaView

    • On Windows, go to Start → All Programs → ParaView 5.x.x → and click ParaView
    • On Mac, in the finder, go to the ParaView directory (in the Application directory where you installed ParaView) and click on “paraview”.
    • On Linux go into the ParaView directory (where you downloaded ParaView) and type “paraview”.

Startup Screen

    • The Startup Screen includes two important links. Both of these links can also be found from the Help menu. They are Getting Started Guide and Example Visualizations.

Open can.ex2

  • Open can.ex2.
    • can.ex2 is one of the datasets included with ParaView in the Examples folder.
    • In ParaView, File → Open. In the upper left corner, there is a folder called Examples. Go into this folder. Select can.ex2. Click OK.
    • Under the Properties tab, select all Variables using the square to the left of the label Variables.
    • Click Apply.


  • Turn off the node variables for ACCL. Since any variable that is selected takes up memory, and since some datasets are huge, often the user will only read in the data that is needed for a run.
    • Click ACCL, turning the check box OFF.
    • Apply.
  • The screen should now look like this. (The square will show up as red, since ParaView defaults to coloring by block, and the block we are seeing is red.) You are looking at the bottom of the plate that the can is sitting on.

  • Lets move the 3d object. Grab the can using the left mouse button. Try the center button. Try again with the right button. Try all three again holding down the <SHFT> key. Try again holding down the X, Y and Z keys.
  • Place your mouse on a corner of the can. Now, hold the <CTRL> key down, and move the mouse up and down. You can zoom into and out of that location.
  • Now the screen looks like this:

  • Notice that the can dataset is being painted in two colors -
  • To change the representation, change Surface to Wireframe (right below Help). Then, change it to Surface with Edges. Finally, turn it back to Surface.
  • Change the variable used for color. Change this from Solid Color to Displacement (Point DISPL). (This is found just below the Sources menu.) Everything should go blue.

    • WHAT IS HAPPENING: The can dataset has displacement information in it. We are actually running the plate into the can, and the whole object is moving.
    • TIP: Our color map is not set correctly. It needs to be set over the whole range of displacement, so that it grades from blue to red.
    • WARNING: Very, very large data can take a long time to process. Don’t animate your data unless you have to with very large datasets.
    • Click the single right arrow, running to the end of the simulation.
    • Click the Rescale to Data Range button.
    • Rewind using the animation control furthest left arrow, then click the single right arrow again.

Getting back GUI components

    • If you accidentally close the Properties tab, the Information tab or the Pipeline tab, open them again from the View menu.
    • If you accidentally undock one of the tabs, just drag it back into place, wait for a gray shadow to appear, and drop it into place.
