| - | ====== Editing 3D Grids (Voxel Modeling) ====== | ||
| - | |||
| - | This tutorial describes how to create a geological model with the use of voxels in GeoScene3D. The model operates with three pre-defined 3D grid objects (Lithology, Probability and Geological Era). These are made for modeling the lithology, the probability of the interpretation and finally the geological era. | ||

| - | ==== Requirements ==== | ||
| - | |||
| - | === Module === | ||
| - | |||
| - | FIXME | ||
| - | |||
| - | === Data === | ||
| - | |||
| - | **NOTE**: This tutorial is based on data from Denmark and Danish Geology. You can define your own list of symbols and the geological settings at your modeling location. | ||
| - | |||
| - | ---- | ||
| - | |||
| - | ==== Step 1. Preparations ==== | ||
| - | |||
| - | 1. Open a new project, e.g. the one you created in the tutorial, [[: | ||
| - | \\ | ||
| - | 2. Right-click the “Objects” key node in the “Object Manager” and select the "Setup Model Data Wizard" | ||
| - | {{: | ||
| - | |||
| - | ==== Step 2. Setup Model Data Wizard ==== | ||
| - | |||
| - | The wizard prepares and adds multiple datasets for modeling; in this tutorial we will create three 3D discrete value grids for the voxel modeling.\\ | ||
| - | \\ | ||
| - | 1. Open the wizard.\\ | ||
| - | \\ | ||
| - | 2. In the "Model Type" page, select the "3D Model/Voxel Model" | ||
| - | \\ | ||
| - | 3. In the "3D Grids" page, add three new 3D grids and give them following names:\\ | ||
| - | Lithology\\ | ||
| - | Probability\\ | ||
| - | Geological Era | ||
| - | |||
| - | \\ | ||
| - | 4. Select the “Discrete Value Grids” radio button at the bottom of the page 2. Press " | ||
| - | {{: | ||
| - | \\ | ||
| - | 5. In the “Symbols” page, you setup the list of symbols for all three 3D grids. The default list of symbols is taken from Jupiter, The National Well Database of Denmark.\\ | ||
| - | \\ | ||
| - | 6. Press “Select/ | ||
| - | \\ | ||
| - | 7. When you have finished the list of symbols, press “Next”. | ||
| - | |||
| - | **Note:** In the Model Data Setup Wizard, all three 3D grids get the same list of symbols. You can define a unique list for each 3D grid afterwards, see step 3.2. | ||
| - | |||
| - | In the "Grid Geometry" | ||
| - | 8. In this tutorial we use the Scene Extent. Press the “Scene Extent” button.\\ | ||
| - | \\ | ||
| - | 9. Specify the vertical grid extent as:\\ | ||
| - | Zmin = -200\\ | ||
| - | Zmax = 100\\ | ||
| - | \\ | ||
| - | 10. Specify the node spacing as:\\ | ||
| - | X = 100\\ | ||
| - | Y = 100\\ | ||
| - | Z = 2\\ | ||
| - | \\ | ||
| - | 11. When completed, your vertical grid and node spacing settings should look as below. Press “Next”.\\ | ||
| - | {{: | ||
| - | \\ | ||
| - | 12. In the "Grid Directory" | ||
| - | |||
| - | 13. Press " | ||
| - | In the " | ||
| - | \\ | ||
| - | 14. Use 3D Grids, The 3D Grids Group Name is by default “3D Grids”. Press " | ||
| - | {{: | ||

| - | \\ | ||
| - | 16. The three 3D grids (Lithology, Probability and Geological_Era) are automatically loaded to the project and are ready for voxel modeling.\\ | ||
| - | {{: | ||
| - | |||
| - | ==== Step 3. Select a list of symbology for each 3D grid ==== | ||
| - | |||
| - | Going through the “Setup Model Data” wizard, by default, the three 3D grids are given the same list of symbology. Step 3 in this tutorial describes how to change the list of symbols for each 3D grid.\\ | ||
| - | \\ | ||
| - | 1. In the Object Manager, highlight and right-click the 3D grid “Probability” and select “Object Properties…(“Probability”)”.\\ | ||
| - | {{: | ||
| - | \\ | ||
| - | 2. In the Object Properties box, select the “Material” tab and press “Symbols”, | ||
| - | {{: | ||
| - | \\ | ||
| - | 3. Press “Clear” and add three new rows representing the probability of the geological interpretation.\\ | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | 4. Using the same approach as in step 3.1-3.3, you now add symbols for the 3D grid “Geological Era”, see figure 11.\\ | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | ==== Step 4. Start an edit session and apply edits in 3D ==== | ||
| - | |||
| - | The procedure is the same in all editable 3D grids. The lithology 3D grid is used in this example.\\ | ||
| - | \\ | ||
| - | **Start an edit session:** \\ | ||
| - | 1. Select " | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | 2. Press the “Start Edit Session” button {{: | ||
| - | 3. This opens the “Grid Editor” and starts the edit session, see figure 13. | ||
| - | |||
| - | **NOTE**:\\ | ||
| - | The editing shape appears in 3D as a floating geometry and in the map as a circle. By default, the editing shape is an ellipsoid, the shape and size of the editing shape is configurable in the “Grid Editor” window under the “Tools” tab, see figure 13.\\ | ||
| - | \\ | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | 4. Check mark the “Linked Grids” in the grid editor window and the linked grids editor opens, see figure 13 + 14.\\ | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | 5. Under Lithology, select “44_DS_glacial smeltevandssand” (danish terminology for sand) from the dropdown menu.\\ | ||
| - | \\ | ||
| - | 6. Under Probability, | ||
| - | \\ | ||
| - | 7. Under Geological Era, select “Cenozoic, | ||
| - | |||
| - | ==== Step 5. Apply edits in 3D. ==== | ||
| - | |||
| - | Now you are ready to apply edits in the 3D grids. The editing shape can be configured in the “Grid Editor” window and in this tutorial, the editing shape has following parameters, see figure 13:\\ | ||
| - | X = 1000\\ | ||
| - | Y = 1000\\ | ||
| - | Z = 100\\ | ||
| - | 1. To move the editing shape, press the “Move Grid Edit Tool” button {{: | ||
| - | 2. Drag the editing shape to any position as shown in figure 15.\\ | ||
| - | {{: | ||
| - | |||
| - | 3. Press the “Apply changes to grid” button {{: | ||
| - | 4. To see the applied changes, move the editing shape to another position, see figure 16.\\ | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | 5. To stop the Edit session, press the button in the main tool bar. | ||
| - | |||
| - | ==== Step 6. How to visualize node points as node cubes ==== | ||
| - | |||
| - | The procedure is the same in all editable 3D grids. The lithology 3D grid is used in this example.\\ | ||
| - | \\ | ||
| - | 1. In the Object Manager, Right-click the 3D Grid object “Lithology” and select “Object Properties…”, | ||
| - | \\ | ||
| - | 2. Press the “Nodes” tab, see figure 17.\\ | ||
| - | \\ | ||
| - | 3. Set the following properties: | ||
| - | -Check “Node Cubes” to be “Visible”.\\ | ||
| - | -Geometry to “Mesh. Not Mouse Clickable (fast)”\\ | ||
| - | -Visibility Mode to “Not Hidden, shell (fastest)\\ | ||
| - | \\ | ||
| - | 4. For Size, press the button “Set To Node Spacing”\\ | ||
| - | Width (X) = 98\\ | ||
| - | Height (Y) = 98\\ | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | 5. Press “OK”, see figure 18. | ||
| - | |||
| - | **TIP** \\ | ||
| - | Make the width and height of the node cubes a couple of units less than the node spacing.\\ | ||
| - | This makes the node cubes appear as boxes in 3D, see figure.\\ | ||
| - | {{: | ||
| - | <font inherit/ | ||
| - | |||
| - | Repeat step 1 through 3 to visualize the edits as nodes cubes for the other two 3D grids, “Probability” and “Geological Era”, see figure 18.\\ | ||

| - | |||
| - | 4. To stop the Edit session, press the button {{: | ||
| - | |||
| - | **Tip** \\ | ||
| - | If the edited nodes are invisible it may be due to the limit settings. Right-click the 3D\\ | ||
| - | grid object in the object manager, Select “Objects Properties…”. Select the “Limits, values” tab and increase the max node value interval, see figure.\\ | ||
| - | {{: | ||

| - | \\ | ||
| - | 1. In the Grid Editor window, set the “Surface Boundaries - Below” to “Terrain” in the dropdown menu, see figure 22.\\ | ||
