Filtering Data in the 3D Scene

When data tables are displayed in the 3D scene, there are two ways of filtering data to aid interpreting the data. These are:

Filtering Data Using Queries

In Leapfrog Energy, you can define query and volume filters for data tables that select a subset of data for future processing; this is described in the Filtering Data topic. Filters can also be used when displaying data in the scene.

To apply a filter to the scene, select the object in the shape list, then select the filter from the Query filter list in the shape properties panel. For drilling data, any defined volume filters can will also be displayed in the Query filters list.

Choosing a query filter for a table in the shape properties panel, listing the filters defined on the collar table

For a drilling data table, this displays only the data selected by the filter. The trace lines remain displayed in the scene. To filter out the trace lines so they are not displayed in the scene, tick the Filter trace lines box:

The Filter trace lines checkbox ticked so that trace lines are hidden along with the filtered-out data

Using the Display Filter

In the shape properties panel, you can also filter the range of values displayed. In the Display filter field, select the column to use as the value range filter. It does not need to be the same column as that selected in the shape list. Tick the Enable filter box to apply the filter or untick the box to stop using the display filter without discarding your filter selection settings. This allows you to turn the filter on and off easily, without having to redefine the filter each time.

If the column you select for the Display filter is a numeric column, a range slider will be displayed for selecting the values to filter:

A numeric column chosen as the Display filter, with a range slider and value boxes for setting the lower and upper bounds

The lower and upper value bounds can be set by dragging the handles at each end of the range slider, or by entering values into the boxes above the range slider.

Range sliders have two modes: coarse control and fine control. Here a range slider is used for a set of values that ranges from 1 to 160; it is displayed in dark blue, to show the full range of values in coarse control mode:

You can restrict the data displayed by dragging on the handles. Here the range of values is restricted to 1 to 50:

You can click and drag on the selected range to change the values displayed:

To switch to fine control, double-click anywhere along the range slider. Here the range of 52-101 has been expanded along the whole slider, giving you more control over the position of the range end points:

Double-clicking a range slider switches to fine control, expanding the selected range of 52 to 101 across the whole slider

The slider is displayed in light blue in fine control mode.

Now you can use the handles to further restrict the range displayed:

In fine control mode, moving the handles inwards further restricts the range from 52 to 101 down to 60 to 80

Right-click on the slider to return to coarse control and the full range of values. Here, right-clicking reverts to coarse control, with the range restricted to the original range of 52-101:

Right-clicking a range slider returns it to coarse control, restoring the earlier range of 52 to 101

If the column you select for Display filter is a category column, the options for selecting the values to filter will look like this:

A category column chosen as the Display filter, with Select Categories opening a legend where each category can be shown or hidden

Click the Select Categories button to open a dialog that will allow each individual category to be shown or hidden.

If the column you select for Display filter is a date/time column, the options for selecting the values to filter will look like this:

A date/time column chosen as the Display filter, with date buttons above the range slider that open a date picker

The lower and upper value bounds can be set by dragging the handles at each end of the range slider, or by clicking the date buttons above the range slider, which will open a date-picker dialog.

When the range slider is set to a portion of the whole value range, it can be clicked and dragged to move both the lower and upper limits by the same amount. This is handy when specifying a particular window which you can then drag across the whole range to observe the effect in the scene.

These range sliders have a feature that helps with fine refinement of the value range selection. Double-click on the range slider:

The slider will change to a pale blue and while the lower and upper limits remain the same, the slider has changed to fill the whole width of the shape properties panel.

After double-clicking, the slider changes to pale blue and the selected range of 1.54 to 3.347 is stretched across its whole width

You can then manipulate the lower and upper end points, and because the range has been restricted, you have finer-grained control as you move the range slider handles.

With the range expanded across the slider, the handles can be moved for finer control, here narrowing the range to 1.673 to 3.112

You can double-click the range slider to zoom in even further for higher resolution control.

To return to the previous level of range selection, right-click the range slider.

Zoomed in a further level, with the range 1.673 to 3.112 now filling the whole slider

Repeat the right-click on the range slider again to go back another level.

Right-clicking has stepped the slider back one zoom level, to the range 1.54 to 3.347

When you get back to the original range selection zoom level , the range slider will change back to dark blue.

Right-clicking again returns the slider to its original zoom level, shown by the dark blue bar spanning 0.02 to 9.29

Right-clicking the range slider at this point will revert the range selection to the full value range.

A final right-click reverts the selection to the full value range of 0.02 to 9.29
