Apply a Polygon Filter to a Solid Model - RockPlot2D Polygons

RockWorks | ModOps | Solid | Filters | RockPlot Polygon Filter

This program reads (1) an existing RockPlot2D map (.Rw2D file) which contains one or more polygons and (2) an existing solid model (.RwMod file), and sets the model's nodes which lie either inside or outside a vertical projection of the polygon(s) to "0" or to null. This is a handy way to filter a solid model with multiple polygons.

Use: Filter a lithology model based on one or more property boundaries saved in a RockPlot2D map.

Feature Level: RockWorks Basic and higher

• Rules & Filters: Use the buttons at the top of the window to apply filters and rules for this program. (More info)
  • Spatial Filter: Filter the input data to be displayed in striplogs, if activated.
  • Time Filter: Filter any T-Data or Aquifer data in striplogs, if activated.
  • Stratigraphic Rules: Apply stratigraphy rules for Stratigraphy data in striplogs, if activated.

• 3D Log Design
  If you decide to include logs with this diagram ("Striplogs" setting, below), click on this button at the top of the window to set up how you want the 3D logs to look.
  See Visible Item Summary and Using the 3D Log Designer for details.

• Input/Output Models
  • Input Model: Click to the right to browse for the name of the existing RockWorks solid model (.RwMod file) that the program is to read and filter.
  • Output Model: Click to the right to type in the name to assign to the new solid model that the program will create, which results from the polygon filtering operation.
  • 
    
• Options:
  • RockPlot2D Polygons: Click to the right to browse for the name of the existing RockPlot2D map (.Rw2D file) which contains the polygon(s) to be used to clip the solid model.
    ! If the RockPlot2D map contains polygons which you don't want to use for clipping - such as closed contour lines or other shapes - you can disable those layers in RockPlot2D and they will be ignored here.
  • 
    
  • Replace Nodes Inside Polygon: Choose this option to re-assign node values that lie inside a vertical projection of the polygon outline(s), using the replacement value defined below.
  • Replace Nodes Outside Polygon: Choose this option to re-assign node values that lie outside a vertical projection of the polygon outline(s), using the replacement value defined below.
  • Replacement Value: Select the value to be assigned to the replaced nodes.
    • Null: Click in this radio button to assign a RockWare null value to the replaced nodes. A "null" setting will set the nodes inside or outside of the polygon to a value that RockWorks interprets as "undefined" thereby rendering these regions invisible when displaying the models. Null values are also excluded from volumetric calculations.
    • Other User-Defined Value: Click in this radio button to assign a specific numeric value to the replaced nodes.
      • User-Defined Replacement Value: Type in the specific value which will be assigned to the solid model nodes.

• 3D Solid Diagram
  Insert a check here to display the output solid model as a 3D diagram.
  Click this tab to set up the diagram options.
  • Block Diagram
    • Isosurface: Click in the Isosurface radio button to display the solid model as if enclosed in a "skin." This view will be smoother than a voxel display. (More info)
      • Isomesh: Check this box to plot a series of polylines that represent three-dimensional contours at a user-defined cutoff. Click this tab to establish the settings. (More info)
    • Voxels: Click in the Voxels radio button to represent the solid model in the 3D display as color-coded voxels. You can choose to display either the Full Voxel, or just the Midpoint. Display of the midpoint only can significantly improve display time for huge models.
    • 
      
    • Filter: Check this option if you want to restrict the isosurface or voxel display to a specific data range. This does not affect the model, only the display of the model. Enabling this permits you to create an initial display in RockPlot3D that eliminates the need to manually change the display attributes. More importantly, this capability if essential for initially displaying the solid in a pre-filtered state when creating animations and Playlist scripts.
      ! These filter settings can be changed once the diagram is displayed in RockPlot3D.

    • Color Scheme: Choose the color scheme for the block model - automatic, table-based, etc. (More info)

  • Striplogs: Check this item to include 3D logs with the output model display. Click the 3D Log Design button at the top of the window to set up how you want the logs to look.

Step-by-Step Summary

1. Double-check that you have the following: A real number RockWorks solid model, and a RockPlot2D map that contains one or more polygons to be used to filter the solid model. These will be the input files for this program.
2. Select the RockWorks | ModOps | Solid | Filters | RockPlot Polygon Filter menu option.
3. Enter the requested menu settings, described above.
4. Click the Continue button to proceed.

   The program will load the input solid model, determine whether each node lies inside or outside of the polygon(s) stored in the RockPlot2D map, and set the node to the replacement value you requested. Nodes that are not reset are left unchanged. The resulting node values will be stored in a new solid model on disk under the output file name you selected. If you have requested a diagram, it will be displayed in a RockPlot3D tab.

5. You can adjust any of the input options in the main Options tab to the left, and then click the Continue button again to regenerate the model and display.
6. View / save / manipulate / print the image in the RockPlot3D window.
