Leapfrog Mining 2.5 release

Below are the feature updates from version 2.5. This latest release includes improvements to these features to better enhance your Leapfrog usability and enrich your experience.

Grid of points

Leapfrog now supports a new oriented grid of points that allows users to rotate or snap a grid onto a point, plus various other gridding workflows. Domains can be evaluated on the grid and exported as Surpac and GSLib formats.

Structural data down drillholes

Users can now import structural data on orientated core specified by dip / azimuth or alpha / beta measurements at depths down drillholes.

De-survey compatibility mode

Leapfrog now supports a new drillhole de-surveying compatibility mode. The new balanced tangent mode enables better interoperability with other packages such as Vulcan and Minesight.

Mesh operations

Meshes can be offset by a vector for easy repositioning. Mesh vertices can now be extracted to appear as a set of locations to allow for easy resampling and resizing of any mesh.

Drillhole drift

Drift adjustment for planned drillholes is now supported in Leapfrog.

Enhanced drillhole display

Labels rendered on boreholes in the scene can be configured to display data from multiple columns in Leapfrog 2.5, enabling even more of your data to be visible at once.

Import / Export

Functionality has been added to support Surpac, GSLi and GeoTiff file formats. As well as the exporting of interval selections as lithology segments and the importing of meshes and lines from layered DXF files.

Interpolant diagram

The variogram tab for interpolants now includes a diagram to view the effect of the variogram parameters.

Drillhole planning tool enhancements

The drillhole planning tool has been significantly improved for planning large numbers of holes:

• A standard offset allows the rapid generation of drilling pickets.
• A drag operation allows the user to specify both the start and end of a drillhole.
• The exporting of multiple drillholes in collar/survey/interval format is now supported.
• The user can now specify any mesh to define the topography.

Select within a domain

• The user can now select within a domain using either the mathematical functions or the boundary mesh. The latter is slower but can be used to export a consistent boundary and point selection to software that does not support radial basis functions.
• The domain object and its boundary have been merged into a single object to reduce clutter in the tree and make complicated geological models easier to understand.

Software Interface with ALS Webtrieve™

• ARANZ Geo and ALS Minerals now offer seamless interaction between Leapfrog 3D modelling and ALS Webtrieve™ data retrieval service. Now users can rapidly visualise core data in 3D and access Webtrieve™ for checking and verification. Right click on the Drillhole Data folder to view individualcore photographs.

Points

• Point attributes (e.g. values & labels) are retained when points are projected.
• When projecting points & polylines the user can now select whether to discard or keep points which are not projected (i.e. these points which are not vertically above the mesh).
• Volume point extraction has been modified:
• Default for ‘Convert Ignored Intervals’ is now ‘No’.
• A new ‘contact points’ object appears in the project tree under the volume points. It contains the volume points at distance 0 – i.e. the boundary of the volume points. These contacts can be used for offsetting the boundary mesh.

Bounding Box

• It is now possible to use a bounding box as data for creating another bounding box (it is therefore easy to make a new bounding box which is a little larger than another one).
• The interface now uses different icons to distinguish fixed and data dependent bounding boxes.
• The bounding box dialog has been split into two separate dialogs – one for creating & editing ‘Fixed’ bounding boxes and another for creating & editing ‘Dynamic’ (data dependent) bounding boxes.

Icons/dialog/keyboard shortcuts

• The interface now uses different icons to distinguish structural data tables and drillhole data tables.
• The properties dialog for grade shells now shows the approximate grade within the shells.
• Keyboard shortcut ‘m’ & ‘M’ have been added to look at the moving plane.

Exporting saved scenes

• The user interface for exporting saved scenes has been improved to allow the user to select previously saved scenes.

Importing Meshes

• Vulcan 8 meshes can now be imported into Leapfrog.
• Datamine Binary meshes can now be imported into Leapfrog.

Comments tab

• There is now a 'Comments' tab on the properties dialog for all objects to allow users to add comments to almost any object.
