iMOD User Manual version 4.4 (html)


7.33D Tool

WHY?
The 3D Tool can be used to visualize raster data (IDF), point data (IPF, with/without boreholes), polygon data (GEN), flowline data (IFF) in a 3D viewing environment.

WHAT?
iMOD is equipped with an OpenGL library (Open Graphics Library) that is a standard specification for writing applications that produce 2D and 3D computer graphics. OpenGL was developed by Silicon Graphics Inc. (SGI) in 1992 and is widely used in CAD, virtual reality, scientific visualization, information visualization, flight simulation, and video games.

HOW?
To use the OpenGL functionalities in iMOD, simply select the map(s)(IDF, IPF, IFF, GEN, MDF) from the iMOD Manager and select the option Toolbox from the main menu and then choose the option 3D Tool to start the 3D Tool.

Example of the 3D tool:

pictures/h5/image639.png


7.3.1Starting the 3D Tool

The 3D Tool starts by selecting the 3D Tool option from the main menu option Toolbox. Alternatively, the  pictures/h1-h3/image26.png -button can be selected from the main window. In the situation IDF files are selected in the iMOD Manager window, the 3D IDF Settings window pops up. In this window each IDF can be configured how it is presented in 3D.

pictures/h5/image651.png

Set all Types to

Select the type for all IDF files, any individual modification can be done in the table. Select one of the following:

Planes
Select this option to compute the 3D image as quadrilateral between the cell mid of four adjacent cells.

Example of a planes representation.

pictures/h5/image652.png

Cubes
Select this option to present the IDF using the individual grid cells values as constant for each individual cell.

Example of a cubic representation.

pictures/h5/image653.png

Voxels
This option is selected automatically whenever the IDF-file represents a voxel (see Section 9.5 for the syntax of an IDF file and how to switch to a voxel representation for an IDF file).

Example of a voxel representation.

pictures/h5/image654.png

Vectors
This option is selected automatically whenever the IDF represents a vector field. See Section 9.5 for more information about vectors. Use the iMOD-Batch function CREATEIVF to create vector IDF’s.

Example of a vector representation.

pictures/h5/image655.png

Off
Select this option to turn the IDF off temporarily.

Table: IDF (top)

Displays the current name of the IDF-file, combined with another IDF this would be the top. It is not possible to change the entry.

Table: Type

A type can be selected per individual IDF. For the available types see the ’Set All Types to’-description above.

Table: Combine With
(bottom):

Select the IDF-file from the drop-down menu that needs to be combined with the IDF-file specified in the first column (IDF (top)) of this table. In this way the first IDF will be used to identify the top of the solid, the ’Combine With
(bottom)’
IDF will be the bottom. It gives a solid representation of these two IDF’s.

Table: Legend By:

Select the IDF-file from the drop-down menu for which the associated legend needs to be used to colour the 3D representation of the IDF (top) in combination with the entered IDF at Combine With (bottom). Several possibilities arise, you may want to colour an IDF using an associated legend of another IDF and/or whenever two IDF-files are combined as a solid, it could be coloured by an associated legend of an IDF that represent the permeability of the solid. Use the different options at Configuration to modify the setting in the table automatically.

Configuration

Select an option from the drop down list Configuration to display a layer model using a predefined display mode.

Interfaces
Use this option to represent each IDF separately as an interface.

Example of an Interface visualisation.

pictures/h5/image652.png

Quasi 3D model (aquitard)
Select this configuration to arrange the Table such that the first IDF will be the top surface level and presented as a white fishnet. Further downwards, IDF number 2 will be combined with number 3, number 4 with number 5 and so on. The last IDF will be presented as a normal plane. This option is especially handy whenever a Quasi-3D model needs to be presented showing aquitards as solid bodies.

Example of a Quasi 3D visualisation of aquitards.

pictures/h5/image656.png

Quasi 3D model (aquifer)
Select this configuration to arrange the Table such that the first IDF will be the top aquifer and combined with the second surface; further downwards, IDF number 3 will be combined with number 4, number 5 with number 6 and so on. This option is especially handy when a Quasi-3D model needs to be presented showing aquifers as solid bodies.

Example of a Quasi 3D visualisation of aquifers.

pictures/h5/image656b.png

3D Model
Use this configuration to combine each IDF with the following IDF, so IDF number 1 will be combined with IDF number 2 and that will be combined with IDF number 3.

Example of a 3D Model visualisation.

pictures/h5/image657.png

Coloured Quasi 3D Model (aquitard)
Use this configuration to present and colour aquitards by sets of 3 IDF’s per aquitard using the associated legend of each second IDF of that set of 3 IDF’s to colour the aquitard. The first IDF will be draped as a white fishnet. Then it will combine the second with the fourth IDF to form a solid and colour it by the associated legend of the third IDF. Then it will combine the fifth with the seventh to form a solid and colour it using the legend of the sixth, and so on.

Example of a coloured Quasi 3D (aquitard) visualisation.

pictures/h5/image658.png

Coloured Quasi 3D Model (aquifer)
Use this configuration to present and colour aquifers by sets of 3 IDF’s per aquifer using the associated legend of each second IDF of that set of 3 IDF’s to colour the aquifer. It will combine the first with the third IDF to form a solid and colour it by the associated legend of the second IDF. Then it will combine the fourth with the sixth and colour it by using the associated legend of the fifth, and so on.

Example of a coloured Quasi 3D (aquifer) visualisation.

pictures/h5/image658a.png

Coloured 3D Model
Use this configuration to present a complete 3D model with the first IDF combined with the third to create a solid and colour it according to the associated legend of the second IDF. Then it will create a solid with the third and fifth IDF and colour it using the associated legend of the fourth IDF and so on.

Example of a coloured 3D Model visualisation.

Accuracy

Select the accuracy of the representation of the loaded IDF-files. To increase the performance select a lower resolution, to increase the accuracy of the representation select a higher resolution. Bear in mind that a high resolution will need more resources from the graphical card. If this fails, then iMOD will crash. Choose from:

  • Minimal (100 x 100):
    IDF-file will be represented by a maximum 100 x 100 cells;

  • Low (max 250 x 250):
    IDF-file will be represented by maximum 250 x 250 cells;

  • Normal (max 500 x 500):
    IDF-file will be represented by maximum 500 x 500 cells;

  • High (max 750 x 750):
    IDF-file will be represented by maximum 750 x 750 cells;

  • Very High (max 1000 x 1000):
    IDF-file will be represented by max 1000 x 1000 cells;

  • Maximal (max ncol x nrow):
    IDF-file will be represented by maximal the size of the IDF, e.g ncol x nrow cells.

Sampling

Select the method of upscaling whenever the chosen Accuracy is lower than the dimensions of the original IDF-file. Select from the dropdown list, for more detail about these type of upscaling, go to Section 6.7.3.

Apply

Click this button to to close the 3D Plot Settings window and apply the chosen display configurations and start the 3D Tool window.

Help …

Click this button to start the Help functionality.

Cancel

Click this button to close the 3D Plot Settings window, the 3D Tool window will not start.

Note: Bear in mind that iMOD will blank out all elements of an IDF that have a white colour. In this way it is easy to blank out a specific area, such as high permeable areas by giving them a white colour.

Note: It is possible to select the configuration of the table and paste it into e.g. Excel. From there may it might be easier to detail your configuration and copy and paste it from Excel to the iMOD your configuration-table of the 3D Tool Settings window.

OK
Click this button to generate the artificial boreholes. The artificial wells will be saved in the folder {iMOD_USER}\TMP \3D \ARTWELL \ARTIFICIAL_WELLS_{i}.IPF. Each time an additional set is created \(i\) becomes \(i+1\) and they are sequentially added to the IPFs-tab on the 3-D Tool window. Additional, a DLF is created (see Section 9.18) that is used to colour the individual interfaces along the boreholes. iMOD assigns that legend to the boreholes automatically. The colours are those assigned to the individual IDF files.
Note: After leaving the 3-D Tool, iMOD asks to remove the set of artificial boreholes via:

Question upon leaving the 3-D Tool.

Deact. Associated Files

Click this checkbox to ignore the associated files that are attached to the selected IPF file. This checkbox will be greyed out whenever no associated files are available and/or automatically deselected for associated files that represent time series as they can not be displayed in a 3D environment. For IPF files with boreholes this checkbox will deselected by default. When this option is selected, iMOD will use the columns from the IPF file that are assigned to the Z-coordinate and if applicable the Sec. Z-Crd., see section Section 6.8.1. In this way iMOD will create spheres (only Z-coordinate is assigned) or vertical tubes when both attributes are assigned. It is also possible to colour the tubes/spheres according to the attribute Apply Colouring To that is assigned for colouring.

Example of a tube (top figure) and sphere (bottom figure) representation of an IPF file with deactivated/no associated txt files.

Legend Number:

Select one of the ten predefined legends from the drop down menu. Each time another item is selected, the current legend from the table below will be saved in that predefined legend number. In this way a multiply set of legends can be managed efficiently.

Legend for boreholes

Table of the legend used for colouring the boreholes associated to the selected IPF file(s).

Label
The first column will be used to represent the label that need to be matched (case insensitive) with a particular column in the associated files (Cylinder Class Column, see section Section 6.8.2). This is the number of the column in the associated files that need to be used for the size of the cylinders plotted for the boreholes.

Clr
The second column will be used to represent the colour that will be used for those items that match the entered label in the column Label.


Description
The third column is for descriptive purposes only. This will be the actual text that will be plotted in the legend on the 3D window.

Width:
The fourth column can be used to specify a particular width to the individual parts of the borehole.

Example of Borehole with constant width (top figure) and variable width (bottom figure)

7.3.63D Tool: the GEN-settings tab

Use the GEN Settings tab to configure the display of GEN files.

pictures/h5/image683.png

Loaded GENs, select one of more to update settings

Select one or more GEN-files from the list to activate them in the 3-D visualization. The 3-D display will update each time a GEN is (de)selected. GEN-files can be loaded in the Maps tab or the Overlays tab in the iMOD Manager; the behaviour is different and illustrated below.

Overlay tab
This is the most common way to load GEN files into iMOD. Each selected file from the Map tab on the iMOD Manager will be presented as a separate entry for which all setting described below can be set. There are two options for a GEN file (see section Section 9.11 for more detailed information):

2-D GENs
These are the most common files and used for topographical information, such as e.g. road and borders.

Example of a display of 2D GEN showing, rivers (blue), urban area (red) and roads (green).

pictures/h5/gen_2d_example.png

3-D GENs
These can be used to display 3D spatial information, such as faults in 3D.

Example of a display of 3D GEN showing a fault outline.

pictures/h5/gen_3d_example.png

Map tab
Whenever a GEN file is selected in the Map tab on the iMOD Manager window, the GEN files acts as a cookie-cutter. In this way it is possible to cut-out e.g. solids using irregular shaped polygons and display these in 3D.

Example of an irregular shaped GEN file acting as a cookie-cutter in the 3D.

pictures/h5/gen_cookiecutter.png

Thickness

Enter the thickness of the lines used to display the GEN-files.

7.3.73D Tool: the Fence Diagrams-tab

The functionality of this tab Fence Diagram is twofold. It will be used to display cross-sections as fence diagrams from the SOLID Tool (see section Section 7.4 and secondly whenever the regular 3D Tool is started, this tab allows to interactively draw the location of a fence-diagram, iMOD will convert this to a fence diagram and display it on the graphical display.

pictures/h5/image687.png

Loaded Cross-Sections

Select one or more cross-section files from the list to activate them in the 3D visualization. The 3D display will update each time a cross-section is (de)selected.


pictures/h1-h3/image102.png

Draw
Select this button to start drawing a cross-section in the 3D graphical canvas. The line is started by clicking the left-mouse button and terminated with the right mouse button. After that, iMOD generates a fence-diagram and adds it as a separate entry in the menu list; the naming convention is {Cross-Section_yyyymmdd_hh_mm_ss}. Subsequent left-mouse clicking will insert additional nodes to the same cross-sections. Be aware that it is necessary to select at least one IDF file, as it is only possible to draw a cross-section over an IDF that is visible; do not use transparency!

Example of a cross-sections drawn on lower most IDF file (top figure) and the yielding fence diagram (bottom figure).

pictures/h5/draw_fence_diagram.png

pictures/h5/draw_fence_diagram2.png

Note: It is important to note that the appearance of the fence-diagram depends on the configuration of the individual interfaces. So whenever you pick the Quasi 3D Model (aquitard) configuration, the fence-diagram appears as filling the aquitard only. Moreover, if you select the Coloured Quasi 3D Model (aquitard) configuration, the fence-diagram is filled in with the property that is selected.



Example of a cross-sections drawn for aquitards only (top figure) or filled in by the selected property (bottom figure).

Click this button to open an *.SPF file (see Section 9.22). This file described the entire cross-sections per interface and can be used in the SOLID Tool (see Section 7.4).


pictures/h1-h3/image104.png

Save As SPF File
Click this button to save the selected cross-sections to an *.SPF-file (see Section 9.22). This type of file can be used in the SOLID Tool (see Section 7.4). The SPF file is saved with the name of the cross-sections in the iMOD TMP folder at the user folder associated to the PRF-keyword USER (see section Section 9.1), e.g. IMOD_USER \TMP \*.SPF.


pictures/h1-h3/image105.png

Delete
Click this button to delete the selected cross-section(s) from the list. This action can not be undone, however, you will be asked first whether you are sure to delete the cross-section(s).

Snapping Tolerance

Enter a value for the snapping tolerance, the smaller the more accurate the computed fence-diagram becomes. This value denotes that acceptable error between the estimated fence-diagram and the true IDF value at that location. The higher the snapping tolerance, the more this is allowed to differ but, generates a fence-diagram with less points.

Display Attached Bitmaps

Check this box to display the attached bitmap on the cross-section. Those bitmaps need to be added to the cross-section by the Profile Tool (Section 7.1) that has been started by the Solid Tool (Section 7.4) and need to be available in the SPF file (Section 9.22).

Example showing an image of a geological profile attached on the cross-section.

7.3.83D Tool: the Clipplanes-tab

The ’Clipplanes-tab’ of the 3D Tool allows configuring the clipping planes. With clipping planes it is possible to clip part of a 3D image and observe what is behind the clipping plane. In the IDF-tab (see section Section 7.3.3), the IPF-tab (see section Section 7.3.4), and the IFF-tab (see section Section 7.3.5) it is possible to activate the clipping planes. It is possible to e.g. clip IDF files but leave IPF files intact.

pictures/h5/image688.png
