Filtering G Values from the RockPlot3D Voxel Model Display

Step-by-Step Summary

Follow these steps to filter out high and/or log G-values from display in the 3D voxel model.

In the Data pane of the RockPlot3D window, right-click on the name of the solid voxel model to be modified, and choose Options.
Filter: Locate this section of the Solid Options window. You will see a Low and a High slider bar. Below the sliders, you will see the minimum and maximum node value.
- Enable: Insert a check here to activate a filter and enable the slider bars.
- Low: Drag the Low slider from left to right to remove low G values from the solid display. The current low value setting is displayed in the prompt to the right. You may also type a value into the prompt box.
  As you adjust either or both filters, you can see the screen updated (you may need to move the Options window).
- High: Drag the High slider from right to left to remove high values from the surface display. The current high value setting is displayed in the prompt to the right. You may type a value into the prompt box.
If you prefer not to use the slider bars, you can type the desired minimum and/or maximum values directly into the prompt box(es). In this example, a lithology model is filtered to values of min=2 and max=2, to display only "clay" materials (whose G value = 2).

It is not necessary to click the Apply button to see the filter changes in the model – the display is updated continuously.

Tip: You can click the Info button at the very bottom of the window to see the solid model’s G-value range.
