Applying a Solid Model G Range Filter

RockWorks | Utilities | Solid | Filters | Range Filter

This program deletes high or low G-values from a solid model file, reassigning them a user-specified constant. 

Use:  Filter for specific G values for volume computations.  Re-assign erroneous highs or lows an expected maximum or minimum value.

Menu Options

• 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 range filtering operation.
  
  
• Filters: Expand this heading to set up the filter options:
  • High-Stop / Low-Pass: Insert a check here if you want to filter out (or "stop") high G-values from the input solid model, passing all lower node values.  
    • Threshold: Click to enter the maximum acceptable node value in the input file.
    • Replacement:  Click here to enter the value which all greater node values will be assigned.  You can type in any numeric value as the replacement. To assign a null value you can type in the word NULL or enter the value -1e27.
  • Low-Stop / High-Pass: Insert a check here if you want to filter out (or "stop") low G-values from the input solid model, passing all greater node values. You may activate both filters. 
    • Threshold: Expand this item to enter the minimum acceptable node value in the input file. 
    • Replacement: Click here to enter the value which all lesser node values will be assigned.  You can type in any numeric value to be used as the replacement value. To assign a null value to these filtered nodes, type in the word NULL or the value -1e27.
      
      
• Create 3-Dimensional Diagram: Insert a check here if you want to create a plottable 3D diagram of the resulting solid model. Expand this item to establish the diagram settings. 
  • Diagram Type: Choose Isosurface to display the solid model as if enclosed in a "skin". Choose All Voxels to display color-coded voxels. (More.)
  • Iso-Mesh: Use this option to plot a series of polylines that represent three-dimensional contours at a user-defined cutoff. Expand the heading to establish the settings.  (More.)
  • Color Scheme: Click on the Options button to the right to access a variety of pre-set color schemes, or to create your own.  (More.)
  • Reference Cage: Insert a check here to include vertical elevation axes and X and Y coordinate axes in the 3D diagram. Expand this item to set up the cage items.  (More.)
  • Include Legend: Insert a check here to include an index to the colors and G values in the diagram.  (More.)
  
  

Step-by-Step Summary

1. Double-check that you have a real number RockWorks solid model which will be the input file for this program.
2. Access the RockWorks Utilities program tab. It is not necessary to enter data into the main datasheet because RockWorks will be manipulating an existing solid model. 
3. Select the Solid | Filters | Range Filter menu option. 
4. Enter the requested menu settings, described above.
5. Click the Process button to continue.
   
   The program will load the input solid model, compare each model node G-value to the declared filter range(s), change node values or pass node values unchanged as appropriate, and store the results on disk under the output solid model name. If you have requested a diagram, it will be displayed in a RockPlot3D tab. 
    
6. You can adjust any of the input options along the left side of the window and click the Process button again to regenerate the model and display.

   ! Each time you click the Process button, the existing 3D display will be replaced. 

7. View / save / manipulate / print the image in the RockPlot3D window.
