Exploring Models in the Central Browser Scene

The Central Browser’s Scene View tab is where you can explore the model, make comments and add attachments. This topic describes how to work with the model in the Central Browser Scene View tab. It is divided into:

The best way to navigate in the 3D scene in Central Browser is using the mouse. If you are running Central Browser on a laptop, it is recommended that you plug in a mouse rather than using the laptop’s touchpad for navigation. However, you can also navigate in the scene using the keyboard.

Action Mouse Keyboard
Changing the viewing angle Click and drag to rotate the scene

Press the arrow keys to rotate the scene

For smaller steps, hold down the Shift key while pressing the arrow keys

Zooming in and out of the scene

Panning the scene

Click and hold both mouse buttons, then drag

Hold down the scroll wheel and drag

Hold down the Alt key while pressing the arrow keys
Centre an object in the scene Click the scroll wheel  

The current viewing angle, scale and z-axis scale are displayed in the lower right-hand corner of the scene. Use the Look menu in the toolbar to switch to the different viewing angles:

If you prefer to navigate using the keyboard, use the keyboard shortcuts shown in the Look menu.

The Look menu also contains shortcuts to other standard views that will be available when the slicer or the moving plane are in the scene.

Displaying Data Objects

How objects are organised in a revision reflects how objects are organised in Leapfrog.

Click on an object and drag it into the scene to view it:

To make the most efficient use of bandwidth, more detail about objects is not retrieved from the Central Server until they are displayed in the scene. Depending on your connection speed, you may sometimes notice a lag in the information being displayed after you add an object to the scene. A progress bar indicates that data is being loaded from the server. For example, here, some the four numeric models are still being loaded:

Here three drilling data tables have been added to the scene:

The Show/Hide buttons () are used to determine what objects are visible in the scene.

The controls that appear for each viewed object can be used to change how the object is displayed. Multiple columns in data tables can be selected from the dropdown list:

Clicking on an object in the scene displays more information about it. For example, clicking on an interval displays the data for that interval:

Note that although the data table has nine columns, only one is displayed in the popup window, the RECOV column. This is because only the RECOV column has been loaded from the server. Once all columns have been loaded, all data will be displayed for an interval when you click on it:

Data columns are loaded from the server when they are selected from the object list.

Display options for the different data types that can be published to Central are described in Data Types Supported in the Central Browser.

Different controls are available for different types of objects, but these are hidden until the object is displayed in the scene. Here, one of the contact surfaces that make up the Surface Chronology is visible in the scene:

The controls available depend upon the type of object, but many visible objects have a slider that controls the object’s opacity. To find out what each control does, hold the mouse over the control:

Clicking on an object in the scene highlights it in the object list, and then you can make changes to how it is displayed.

The Slice Mode determines how an object is displayed when the slicer is in the scene. This is useful for seeing relationships between objects. To change the Slice Mode, right-click on an object in the list:

From Scene means that the object will be sliced when the slicer is in the scene, and Unsliced means that the object is displayed as though the slicer were not in the scene.

The Fill Slicer tick box determines whether the object is displayed on the slicer as a hollow object or a filled object.

A key part of exploring a project is seeing relationships between models and the data used to build them, and the way objects are organised helps in demonstrating how something was put together. For example, the geological model called “Lithology” can be expanded to show that it is made up of a Boundary created from two surfaces and a fault system that has no contents (the Faults object). The Output Volumes folder has been expanded to show the volumes the model has been subdivided into.

Objects can be expanded or collapsed, to show as much or as little detail as required. For example, the Surface Chronology object expands to show the contact surfaces used to divide the model volume:

Displaying a Model Over Time

With the timeline along the bottom of the window, you can step through the branch to see how the model has changed over time. The highlighted date, outlined in green, is the one currently displayed in the scene:

For example, the timeline shown above corresponds to the revisions in the “Dacite Dykes” branch shown in this project history:

You can step through the model using the arrows and the Previous (Shift+A) and Next (Shift+D) buttons/shortcuts.

The branch selected is always displayed in the top left-hand corner of the scene:

Drawing Slices

With the slicer, you can cut away part of the scene to see the internal structure of an object. To draw a slice, click on the Draw slicer button (), then click and drag in the scene. Release the mouse button at the end point.

The slicer appears in the scene and the Select tool () is selected once again so you can rotate the scene to see the slice clearly. Additional tools appear in the toolbar that allow you to control the size and position of the slice.

Click the slicer tool’s dropdown list to change how the model is cut away from the slice. The three slice modes () determine how the model is cut away from the slice ( ).

Enable the Lock Slicer to Camera option to change the position of the slice as you rotate the scene.

You can also change the position of the slice to one of several preset positions by clicking on the Look menu:

When the slicer is in the scene, you can set objects to display sliced or unsliced, which is useful for seeing relationships between objects.

To draw a new slice, click the Draw slicer button (). To remove the slice from the scene, click on the Show slicer button (). Until a new slice is drawn, the current slice can be made visible once again by clicking on the Show slicer button ().

Measuring Distances

To measure distances in the scene, click on the Draw ruler button (), then click and drag in the scene. Release the mouse button at the end point.

The coordinates of the start and end points will be displayed in the scene, together with the distance measured.

To measure another distance, click the Draw ruler button (). To remove the ruler from the scene, click the Remove ruler button (). The ruler will remain in the scene until you remove it or draw a new ruler.

Comments and Attachments

Comments and attachments are important tools for discussing the model.

To the right of the Scene View tab are buttons that open the Comments () and Attachments () panels:

Comments include scenes that you can click on to see what the comment relates to:

Some comment scenes may be marked with a Compare button ():

Clicking such scenes will open a Compare tab in which you can compare selected objects from two revisions. This is discussed further in Making Comparisons below.

To add a comment, click the Add button (). In the window that appears, add your comment:

You can also add a geotag to the comment. Click the geotag button (), then click in the scene to set the geotag’s location.

You can use @mentions to bring others into the conversation and they will receive notifications of the conversation. Simply type @, then start typing the name of the person you wish to mention. Central will suggest matches from the users who are members of the Central installation. Use the arrow keys to scroll up and down the list of suggested users, then press the Enter key to select.

Click OK to close and save the comment. Note that the scene will be saved along with the comment:

If you want to adjust the scene before saving the comment, do so, then click the Save Scene button () in the New Comment window.

Clicking the thumbnail for a comment in the Central Browser or in the Central Portal will display the scene. Central users working on the project in Leapfrog can open the project and then click on the thumbnail to display the scene.

Here, the scene from the comment made in Central Browser is being displayed in the Central Portal:

You can edit and delete comments you have made, although if another Central user has replied to your comment, you will not be able to delete it.

To add an attachment, click on the Attachments button () to open the Attachments panel:

Add an attachment by scrolling to the bottom of the window and filling out the New Attachment fields:

You can enter a URL for the attachment in the URL field or click the Attach File button to navigate to a file on your local drive. Once you have entered all the information required, click Publish.

Making Comparisons

Comparisons are a powerful tool for seeing in the 3D scene just how the model has changed. To compare two revisions, first put the objects into the scene you want to compare. Next click the Compare button () in the toolbar. A Compare tab will be opened, with the selected objects displayed:

The revision list () shows the project history:

Select the revision you want to compare with the first revision. The objects from that revision will be added to the scene, along with controls for changing their appearance so you can see the differences between objects in one revision and the other:

There are two ways to compare changes between objects, using the show/hide buttons and contrasting object properties.

Using the Show/Hide Buttons

Objects displayed in the Compare tab have Show/Hide buttons (), as does the scene as a whole:

To quickly flicker between selected revisions, click repeatedly on the main scene button.

Right-click on a Show/Hide button to display both revisions at once. Here the “Lower Banded Iron Formation” is shown from each revision, but only the data table from the first revision is shown. Note that controls are not visible for the second revision of the data table but two sets of controls are available for the mesh:

Contrasting Object Properties

Another way to compare changes across revisions is using the display controls to contrast objects from each revision. The controls available for objects in the Compare tab are a subset of those available in the Scene View, those most useful for comparing differences between objects. For example, meshes can be displayed as wireframes, which makes it easy to compare two revisions of the same surface:

Drillholes and points have controls that let you change the appearance for each revision. Here, for example, the drillholes from the first revision are shown larger than those for the second, making it clear what data belongs to what revision:

Some controls will apply to both revisions rather than being set individually. An example is filtering of drillholes and points, which filters values for both revisions.

Connecting to IMDEXHUB-IQ™

Some Central projects have permission to access an IMDEX integration. You can visualise data collected at rig in near real time alongside geological data in Central. Data types supported are planned holes, survey measurements and structural data.

When you open a Central project that has permissions for the integration, a button will appear in the toolbar above the scene window:

Click the button to load the integration. An separate tab is opened in which you can connect to the integration and view its data:

Select an IMDEXHUB-IQ™ project to view the data available.

You can add data from the integration to the scene and control how it is displayed in the same manner as you would in the main scene window:

Click the refresh button to view the latest data:

Closing the tab closes the connection to the integration.
