-'''In Summary:''' We imported the data sets we want to visualize and made a database correlation for them. One at a time, we elevated each set with zero height, and then transformed with rotation matrices in order to displace them onto their appropriate axis. In the end we have a product that illustrates the column density maps down the barrel (parallel to the magnetic field) of two colliding flows, along with the two perpendicular CDM cases flanking its sides.

 3. Now we do similarly for the sinks on mass2 and mass3. Their projection, elevation and transform operator attributes can be seen in '''Figures 12 and 13'''.

+=== Potential VisIt Errors ===

+Using both the Elevate and Transform operators yield:
+
+{{{
+Pseudocolor:  viewer: Surface requires 2D plot data.
+}}}
+
+Using both the Project and Transform operators yield:
+
+{{{
+The plot spatial dimensions do not match, 2D vs 3D. Plots need to be in windows with plots of the same spatial dimension.
+}}}
+
+Both of these are elleviated by using all three operators in the order of Project, Elevate and then Transform. Transform could also go first, however VisIt seems less buggy if you denote Project before Elevate. Next to the operators are arrows than can allow you to tell VisIt what you want it to enact first.
+
+=== Summary ===
+We edited our database correlation for the imported chombo files, and added P_mass to our 3D CDM visualization. Similarly to how we created our 3D CDM box, we elevated P_mass three times with zero height, and then transformed with rotation matrices in order to displace them onto their appropriate axes. Unlike the procedure to create our 3D box, we needed to make use of the projection operator due to the particular data type P_mass uses which conflicts with our goal of making a 3D simulation. Once all operators are applied, one will be able to see the sinks on their 3D visualization.
 
 == Using a Script ==
-The script used (okc_to_curve.sh) can be found in the attachments below, along with the original sink file for frame 0 and its three projections. To run the script, copy it into your run directory with the .okc files and execute it. Immediately new curve files should be produced. With this method we simply plot the sinks as a curve file instead of as a pseudocolor variable inherent in the chombo (pmass).
