Tutorial: Append an Isosurface

Estimated time: 3 minutes.

In this lesson, you will add to the view an existing 3D scene that contains a solid model "isosurface" and a floating aerial image.

1. Before continuing, be sure you have completed at least the first two lessons (plot logs and append stratigraphy). Or, if you are rejoining this tutorial after a break, look for the RockPlot3D file Logs + Stratigraphy.Rw3D in the Project Manager tab/pane. Double-click on it to open this view.
   
2. Append the solid model isosurface:
   1. With the logs and surfaces still displayed in the image pane, click on the RockPlot3D File menu and click on the Append option.
   2. Locate the existing solid model image named Tutorial Benzene.Rw3D and click on that file name. Click Open to open that file. (This file should reside in the Samples folder.)
   3. You will see a block now displayed in the image pane, and a new data item "Benzene Soil" in the data pane.
   4. You will also see an aerial photo above the surfaces, an "Airphoto" item in the data listing, and the actual image file name, "1955_Airphoto.png," displayed in the Linked File List to the lower-right.
      
3. Double-click on the Benzene Soil item in the data pane. The program will display the Isosurface Options window.

   

4. Adjust the isosurface filter.
   1. Locate the Iso-Level section in the middle of the window. The defaults show the minimum (left) and maximum (right) values stored in the solid model. The current iso-level value should be set to 29.
   2. Into the Iso-Level Value prompt, type in: 5 and click Apply. This tells the program to display those areas in the solid model with benzene concentrations greater than or equal to 5. You should see the image has changed, displaying a much larger isosurface.
   3. Now type 50  into the isolevel prompt, and click Apply. Now you'll see a much smaller area with such high concentrations.
      
5. Remove the check-mark from the Logs group and/or the Stratigraphic Contacts group and/or the Airphoto in the data pane, to see the isosurface more clearly. Or, you can expand either of those groups to selectively remove logs and/or surfaces.
   
6. Rotate the image to see different views.
   
7. Use the Zoom In tool to click-and-drag an enlargement rectangle, to see a bigger view. You can rotate and pan the image while zoomed in.

   

8. Zoom back out just by clicking the Zoom Out button.
   
9. Save the current view:
   1. Select File | Save As.
   2. In the File Name prompt, type in: Logs + Stratigraphy + Benzene    and click Save.

RockPlot3D will store this new, combined scene under this new name, with an ".Rw3D" file name extension.
