GeoReka!‘s base module, the Envision Module, consists of a 3D view that is interactively linked to the 2D section view. This means that if the section plane is moved in the 3D to slice the data, the section view will be instant updated to show how the section looks at that location and orientation. Most settings, e.g. colour and size, will simultaneously change in the 3D and Sectional view so that they are always in sync.
All data that is imported into the Envision Module will instantly be displayed in the 3D view. This makes visual inspection a breeze.
GeoReka! can import the following data types:
- 3D points, optionally with associated values: text files (.csv or .txt) or Visualization Toolkit (.vtk)
- Drillhole Data: text files (.csv or .txt), VMINE (.vtk) and Devico CSV (.csv)
- Surfaces and solids (wireframes): DXF (.dxf), DTM (.asc), gOcad T-surf (.ts), Wavefront OBJ (.obj), Visualization Toolkit VTK (.vtk), georeferenced elevation images: Tif, JPG, PNG
- Polylines: DXF (.dxf), VTK (.vtk), gOCad PLINE (.pl)
- GIS: Shape files (.shp) and MapInfo (.tab) (only if all files are present!)
- Images like maps, sections, aerial photos (georeferenced or not) GeoTif, Tif, JPG, PNG
- Grids / Block models: VTK, VMINE
Each data object imported into GeoReka! will appear at the top of the list. A single left-click will highlight the settings options of the object below the list. There is no need to hunt for an objects settings. Each object has a number of settings that can be changed like:
- colour: fixed, colour by interval, continuous colour scale
- show labels
- representation: solid surface or wireframe, lines or cylinders
GeoReka!’s flexible set up allows you to group arbitrary data items together in a Folder. Similar to how you would create folders on your computer to organize your files, folders can contain an arbitrary number of data items. This way you control how you want the project to be organized and not the software.
Fluent 3D interaction
A normal Microsoft type mouse with scroll-wheel is the easiest to use. Use left-mouse to fluently rotate the data or zoom with the scroll button. The right-mouse can be used for more fluent zooming or to find the object in the display list quickly. No need to memorize it all or hunt through the list of all items.
Left-clicking on object will display their attributes at that point.
A combination of a rotating orientation indicator and Plunge with Azimuth indicators helps you to always know in what direction you are looking at the data. This means even when zoomed in to small details you will always have a good idea of where you are looking.
In addition, turn on the 3D grid to show grid lines along the axes or use quick keyboard shortcuts to align the 3D view with one of the default orientations.
The Section view representation in 3D has a dual function as it also acts as a data slicer. Each data object can be sliced in 3D and either its outline, e.g. grids and surfaces, or a selection within a distance of the section plane will be displayed on the sectional view, e.g. polylines and points. The high-quality graphics implementation means slicing is smooth and quick even with large data sets.
Data that contains values, e.g. assay or geochemistry data, can be dynamically filtered using a cut-off range and slider. They will also have a legend that can optionally be turned on and moved around to any location. The legend will reflect the colour settings as either colouring by intervals or a continuous scale.
For large scale data like regional topography or other fairly flat data, the Z-scale can be zoomed in (in 3D) to reveal detail otherwise easily missed.
3D Distance Measurements
A convenience tool is provided to measure distances in 3D. Besides the already present legend and axes grids, the 3D measurement tool can provide distance measurements between items.
High-resolutions images of either the 3D or the sectional view can be exported to JPG and PNG. An option to export a batch of sectional views is available as well to quickly create a series of sections at any orientation and intervals.
Alternatively, the current 3D view can be exported as a Kiwiviewer (free android and iOS app) project or a VRML scene (free 3D viewer for on the web).
Some essential settings can be customized to your own preference. For example, the background colour and font sizes.
For presentation or conference displays the 3D view can be set to Auto Spin mode. This means the 3D view will slowly rotate continuously around a customizable point of rotation. The 3D viewer remains active so that you will remain full control over view angle etc. to quickly make adjustments or focus on a particular bit of data when requested.
