Importing Data to be Visualized
################################

There are *three* basic ways to import data into the DREAM3D-NX-NX
visualizer:

-  **loading directly from a file**
-  **loading from a DREAM3D state file**
-  **running a DREAM3D-NX-NX pipeline containing geometry data**

The following sections will go through how to import data using each of
these methods in detail.

Importing Data From a Pipeline
===============================

The main way of importing data to be visualized in DREAM3D-NX-NX is by
running a pipeline containing geometry data. Any *data arrays* contained
inside imported geometries can be used to color the geometry data sets
based on the values within the data arrays.

1. **Load or create your pipeline.** See the :ref:`Creating a Pipeline <CreatingAPipeline>` 
   section in User Interface Overview for more detailed instructions.

2. Click on the Visualization Preferences eyeball icon at the bottom of
   the Pipeline View and make sure **Visualize Pipeline Results** is
   **checked**.

3. **Click the Run button** at the bottom of the Pipeline view to run
   the pipeline.

4. **Select the Visualization tab** if tab is not already active.

   In the center of the DREAM3D-NX window containing the pipeline you just
   ran, make sure the *Visualization* tab is active.

5. Once your pipeline has completed, you will find the pipeline run with
   all of its associated geometries in the *Visualization Browser*
   section of the *Render Properties* tab. Each pipeline run will be
   listed as a heading in the Visualization Pipeline Browser tree along
   with all of its geometries underneath. Representations and filters
   are then listed under each geometry.
   If a pipeline that has already been loaded into the Visualization
   Pipeline Browser tree is executed again, then the pipeline and all
   its children in the Visualization Pipeline Browser tree will be
   reloaded.

Importing Data Directly From a File
====================================

The second method of importing data to be visualized in DREAM3D-NX is by
loading the 3D geometric data directly from a file. There are several
file types supported by DREAM3D-NX for importing into visualization; these
include the following:

-  **.bmp**
-  **.dream3d**
-  **.jpg**
-  **.png**
-  **.stl**
-  **.tif**
-  **.vti**
-  **.vtp**
-  **.vtr**
-  **.vts**
-  **.vtu**

1. Make sure the *Render Properties* view is active. This will be docked
   along the right side of the DREAM3D-NX window by default along with the
   *Data Structure* tab.

2. Right-click an item in the *Visualization Pipeline Browser* section
   of the *Render Properties* view and select the **Load File** option
   from the context menu that appears

      Load via File

3. In the file browser that appears, navigate to the file you wish to
   import and select **Open**. 3D geometric data found in the file will
   be loaded into the *Visualization Pipeline Browser* tree, and any
   color by data arrays contained in the file will *automatically* be
   applied to the geometry when it renders.

Importing Data From a DREAM3D State File
=========================================

The third method of importing data to be visualized in DREAM3D-NX is by
loading a DREAM3D state file (.d3dstate). This will load all of the 
geometry data as well as the entire visualization state from a 
previously saved session. (See :ref:`Saving and Loading State Files<StateFiles>` 
for more details on DREAM3D-NX state files)

*It is important to note that when loading a state file, the current split 
views/render window settings will be cleared and any geometry data currently 
loaded into the visualization might be deleted.* 

1. Make sure the *Render Properties* view is active. This will be docked
   along the right side of the DREAM3D-NX window by default along with the
   *Data Structure* tab.

2. Right-click an item in the *Visualization Pipeline Browser* section
   of the *Render Properties* view and select the **Load State** option
   from the context menu that appears

3. In the file browser that appears, navigate to the state file you wish to
   load and select **Open**. 3D geometric data found in any of the source
   files will be loaded into the *Visualization Pipeline Browser* tree,
   any color by data arrays contained in the source files will *automatically*
   be applied to the geometry when it renders, and all representation, filter,
   and render window settings will be restored.
