Wireframing

The Wireframing module provides the tools for building, managing and analysing 3D solids and 3D surfaces for advanced exploration, resource estimation, mining and geological modelling. It uses powerful and intuitive tools for visually constructing 3D models such as underground mine designs or geological interpretations, using data like centre-lines, profile shapes or polygons.

Watershed and flow-line analyses combined with surface geochemical sampling, created using wireframe tools.

What is Wireframing?

In Micromine a wireframe or triangulation is anything created using a mesh of interconnected triangles. For convenience, wireframes are typically divided into three different kinds:

  • DTM: Has open edges and only ever one Z-value for every X-Y location (although the “Z”-axis may be oriented in any direction)
  • 3D surface: Has open edges but may have more than one Z-value at some X-Y locations. For example an overturned fold will have two Z-values at all locations within the region covered by the overturned limb
  • 3D solid: Is closed and has a measureable volume

Micromine uses different methods to create DTMs and 3D surfaces or solids. However, all existing wireframes are displayed and used in the same way as long as it is appropriate for their topology. (This just means, for example, that a volume can’t be calculated for a DTM or 3D surface.)

Key Features

  • The Wireframe Editing and Wireframe Tools toolbars
  • A centralised management area for wireframe types and their attributes, including creating new types and copying or moving wireframes between types
  • Reporting options such as surface area, volume, and centroid coordinates for multiple selected wireframes
  • The interactive Vizex-based wireframe editor, which includes tools for:
    • Building, auto-building, closing, validating and cleaning wireframes
    • Working with individual triangles (swapping edges, selecting, adding or removing) and triangle vertices
  • Essential DTM tools for creating and validating DTMs
  • Interactive tools such as
    • Centre line to solid
    • Cut, Boolean, intersection strings (polylines)
    • Snap, separate
    • Silhouette, copy/move
  • Utilities include
    • Simplify, advanced repair, separate
    • Transformations such as move, rotate, resize, convert coordinates
    • Volumes
  • Operations such as slice and surface to solid
  • Calculations for
  • Tools for creating wireframes from points, lines, polygons, or other wireframes such as

    • Bedding plane from points
    • Point cloud outer shell
    • Save as single wireframe
  • Tools for generating polylines or polygons from wireframes
    • Boolean intersection
    • Planar intersection
    • Silhouette
  • Grade shell and outer shell creation

  • Numerous Vizex display options including draping, transparency, smoothing, edge highlighting and per-attribute colouring

Key Benefits

  • An intuitive editor that simplifies the construction and editing of simple or complex wireframes, including on-the-fly validation
  • Logically arranged toolbars that offer ready access to all related tools
  • Very strong validation to help you build the best possible wireframe from your data
  • Full snapping support to simplify aligning wireframe vertices to other data
  • An industry-leading, robust and reliable editor with virtually unlimited undo and redo capabilities, giving you the confidence to build even the most complex wireframe
  • No restrictions on input line directions or wireframe construction direction offers greater flexibility with your data, requiring less preparation time before wireframing
  • One-click construction of 3D solids with automatic detection and modelling of bifurcations (“trouser legs”) supports rapid pre-visualisation of a wireframe
  • Straightforward calculation of pierce point depths for predicting orebody intersections in planned drillholes
  • Versatile Boolean operations that simplify the modelling of complex data such as full solid geology or open pit shell solids, where the relationship between wireframes is important
  • Many tools for trouble-free construction of 3D wireframes from other data, such as mine design centrelines or orebody interpretations
  • Flexible tools for constructing wireframes from other wireframes, including converting surfaces to solids, intersecting two wireframes (Boolean), or slicing one wireframe with a series of planes (slice)

A wireframe solid of a proposed open pit sliced into individual benches.

  • Tools for interacting wireframes with other data such as block models, 3D points, or drillholes, make it easy to label points as falling inside or outside a 3D solid. 
  • Assigning values from 3D points back into a wireframe to name wireframes representing mining blocks or scheduling periods, is also easy
  • Rapid wireframe grade/tonnage reporting using point, drillhole, or block model source data

Vizex

The Wireframing module extends the capabilities of Vizex (Visual Explorer), a visualisation environment for displaying, querying and interactively editing multiple data layers.
