Introduction
Studio has an extensive repertoire of commands and functions for creating and manipulating wireframe models. This User Guide explains many of the principles of wireframing and provides guidance, with examples, of much of the functionality.
To create a wireframe a series of strings must be created and then these strings must be linked to form the 3D surface outline.
Solid wireframes can be used to represent a 3D volume, such as: • A zone of high grade mineralization
• An orebody
• A particular lithology
From these wireframes, volumes and tonnages can be calculated, which are useful for determining resources and reserves.
Wireframes can also be used to represent surfaces, such as: • Topography (Digital Terrain Model)
• Pit geometry
Wireframe data are stored in two related files, a triangle file and a points file. Values for all fields except COLOUR are assigned internally, by the system, and may be used for filtering.
FIELD DESCRIPTION
TRIANGLE FILE TRIANGLE Triangle number
PID1 First triangle point ID number PID2 Second triangle point ID number PID3 Third triangle point ID number GROUP Wireframe group ID number SURFACE Wireframe surface ID number
LINK Link number
NORMAL-X NORMAL-Y
NORMAL-Z
Stores the values which define the orientation of the normal of the triangle in the X, Y and Z directions.
TRE1ADJ TRE2ADJ
TRE3ADJ
Stores the ‘adjacency data’, which define open and shared triangle edges.
COLOUR POINT FILE GROUP Wireframe Group XP
YP ZP
X, Y and Z coordinates of the triangle point defined by the PID value.
PID The point ID number (as referenced by PID1 etc in the triangle file).
Wireframe Concepts
A points file is the basis for a wireframe. Each point is joined to several others to form a series of triangles (in the display window) that form the surface (in the visualizer). A wireframe can be viewed in the visualizer, which is useful for displaying the newly created surface (or zone) in 3D. The way the triangles are formed can be controlled; the method used is dependent on the wireframe purpose and user preference.
Wireframe Classification
Wireframes are classified by the following fields which are present in all triangle files:
GROUP - A GROUP can consist of one or more distinct wireframes that have either the same, or different surface numbers.
SURFACE - An individual wireframe SURFACE can be selected from within a GROUP of wireframes. This surface can be either a DTM or a solid wireframe. LINK - Each wireframe surface consists of a number of
individual links, each numbered individually. This classification of wireframes by GROUP and SURFACE provides a means by which wireframes can be identified for
operations such as combining and verifying. It also provides greater control when using the ‘erase’ commands; specific GROUPs, SURFACEs, LINKs and triangles may be selected and erased.
The wireframe GROUP, SURFACE and LINK numbers are stored in both the wireframe points and triangles files as the fields: GROUP, SURFACE and LINK respectively. These values are assigned internally by the system. It is possible to select a wireframe by its GROUP or SURFACE number. Wireframes from different GROUPs can be selected together by using other selection methods such as “filters”.
To give a better understanding of how GROUPs and SURFACEs are defined and used there is a wireframe tutorial.
To display the GROUP, SURFACE and LINK numbers use the
New group nwg new-wireframe
Increments the wireframe group number prior to linking. Used to distinguish between wireframes, and to aid selection.
New surface nws new-wireframe-surface
Increments the wireframe surface number prior to linking. Used to distinguish between wireframes and aid selection.
New triangle ntr dvp-new-triangle
Gives the user the ability to create an individual triangle Select wireframe sw select-wireframe
Selects a wireframe group and surface prior to linking. The command takes the selected group and surface number to ensure a continuous surface and group number when a wireframe is extended.
Selecting Wireframes Introduction
Selection method
Wireframes can be selected: By Attributes, By Group, By Surface, By Filters or By Files. There are two ways of setting the selection method:
• Choosing from the selection method menu (Wireframes | Selection Method):
• Setting the method in the wireframe settings dialog (Wireframes | Wireframe Settings).
Several wireframe commands require the selection of a wireframe; they all honor the chosen selection method. The commands are:
• Wireframes | Boolean Operations (e.g. Union, Intersection etc);
• Wireframes | Verify;
• Wireframes | Tools | Edit Attributes; • Wireframe volumes;
When any of the above commands are run, there will be a prompt to select a wireframe triangle.
By Attributes
sba wf-select-attribute-switch
If By Attributes is chosen then wireframe data with user defined attributes matching those of the selected triangle are isolated. For example, the wireframes illustrated below belong to different
GROUPs. By setting the attributes toggle on, both wireframes can be selected. The wireframe GROUP and SURFACE numbers are ignored on input, and new GROUP and SURFACE values are generated on output. This is particularly useful for ‘re-grouping’ wireframes (see Wireframes | Verify for more details).
By Group
sbg wf-select-group-switch
If By picked wireframe GROUP is chosen then all wireframe data matching the selected triangle’s GROUP will be selected.
By Surface
sbs wf-select-surface-switch
If By picked wireframe SURFACE is chosen then all wireframe data matching the selected triangle’s GROUP and SURFACE values will be selected.
By Filters
sbfl wf-select-filter-switch
If By user defined filters is chosen, wireframe data is selected on the basis of triangle and point filters. To apply triangle filters but not point filters then press the RETURN key at the prompt for point filters. Using the wireframes shown above, the wireframes can be selected using the following filter.
As with the attributes selection method the wireframe group and surface numbers are ignored on input and new group and surface values are generated on output. This is particularly useful for ‘re-grouping’ wireframes (see Verify Wireframe for more details). To get a better understanding of how these various selection methods can be used try the short tutorial at the end of this user guide.
By Files sbfi wf-select-files-switch
Select wireframe by prompting for wireframe point and triangle filenames.
Verifying Wireframes
Verify
wvf wireframe-verify
The Wireframes | Verify command is used to perform a number of validation checks, including:
• Identifying holes within a wireframe surface
• Identifying intersections of different surfaces with different IDs
• Identifying crossovers within, or between, surfaces • Checking for duplicate points
• Renumbering wireframe surfaces.
The Verify command is controlled by a number of settings accessed through Wireframes | Wireframe Settings.
Normal and Adjacency Values
These values are generated automatically for each wireframe. The adjacency values list which triangle is next to a particular side of another specific triangle. Most triangles will have 3 other triangles neighboring them, apart from along an edge of a wireframe.
Normal values lie between 1 and -1, and give an indication of the dip of the triangle. A horizontal surface has a value of 0 and a vertical surface has a value of 1 or -1. The values are positive or negative depending on whether the point is above or below the surface.
The values for the NORMAL-X, NORMAL-Y, and NORMAL-Z fields are assigned when the wireframe is linked whereas TRE1ADJ, TRE2ADJ and TRE3ADJ have their values assigned when the Verify command is run.
The table below shows the adjacency values generated.
Note: PID1, PID2 and PID3 refer to the triangle point ID numbers so
PID1 - PID2 refers to the line joining points 1 and 2.
Value Stored In No adjacent triangle Adjacent triangle is part of the same surface Adjacent triangle has been created from the MERGE Option
PID1 - PID2 TRE1ADJ 0 -1 1
PID2 - PID3 TRE2ADJ 0 -1 1
PID3 - PID1 TRE3ADJ 0 -1 1
It is important to generate these data prior to merging or splitting wireframes. If the adjacency data already exist for the selected wireframe data (i.e the Verify command has been used before) then there will be a prompt for the re-assembly of the adjacency data. Display Open Edges twvb wf-boundary-line-switch
This setting enables open edges, or boundaries of a wireframe, to be displayed during wireframe verification.
Note: these will only be converted to strings if the Convert to Strings option is selected.
Display Shared Edges twvm wf-merge-line-switch
This setting can only be used effectively on wireframe data that have been merged or intersected using the Merge or Split commands (Wireframes | Boolean Operations). Shared edges between the intersected surfaces are assigned an adjacency value of -1 (stored in the fields TRE1ADJ, TRE2ADJ, TRE3ADJ). Each surface is assigned a different surface identifier to enable it to be manipulated independently.
This toggle allows the shared, or merged lines to be displayed during wireframe verification.
Note: these will only be converted to strings if the Convert to Strings setting has been selected.
Display Crossovers twvi wf-intersect-line-switch
The Wireframes | Verify command can be used to check for
wireframe surfaces that contain crossovers, or intersect other surfaces. This setting controls whether these crossovers are displayed.
Note: these will only be converted to strings if the Convert to Strings setting has been selected.
Convert to Strings twcl wf-convert-line-switch
This setting controls whether boundary lines, merge lines and lines identifying crossovers are converted to strings during the
Wireframes | Verify command. Renumber Surfaces twn wf-sfvalue-switch
This setting enables the renumbering of surfaces during verification. It is useful for re-grouping wireframes. The wireframe below consists of two GROUPs. The links between the perimeters belonging to one GROUP and the end-links belong to another. To select this
wireframe as a single entity the surfaces must be renumbered so they are the same.
As the surfaces have the same color, the selection method should be set to By Attributes. This will ensure that all the wireframe data required are selected.
Note: By Filters could also be used, provided Renumber Surfaces is selected. The surfaces will be renumbered during the wireframe verification. The resultant wireframe will have a single GROUP number.
Check for Duplicate Points twcd wf-pid-check-switch
This setting will ensure that adjacent triangles will have common point ID numbers (PIDs).
Note: common triangles points which belong to different GROUPs
cannot have the same point ID number.
Set Point Tolerance sto set-tolerance
For DTM formation no triangles will be created with sides of length less than this tolerance.
For the Wireframe-Verify command, points within this tolerance will be considered duplicates. Any triangles that are degenerate after this point merging will be
discarded.
String Linking Control
Settings
The commands relating to string linking methods can be found in the Wireframes | Linking menu. To control the linking method select (Wireframes | Wireframe Settings).
Select the radio button for the method to be used; the screen capture shows the default.
Minimum surface area method tma
link-area-method-switch
The system will create the triangulation that results in the smallest wireframe surface area. Equi-angular shape method tea link-radii-method-switch
The system will create equi-angular triangles (i.e. equilateral or isosceles triangles).
Ideal for complex geometries.
Proportional length method
tpr
link-shape-method-switch
This option will create triangles which best maintain their proportional position along the string. This option works best where the shapes of the two strings are similar. Ideal for long thin volumes.
The following screen captures show three identical pairs of perimeters; each pair linked using a different one of the methods.
Optimal Linking tlm link-method-switch
Optimal Linking tlm linking-method-switch
If this is selected then several wireframes will be generated internally using different starting points. The final wireframe will be created using the best surface from all those that satisfied the linking criteria. If the Proportional Length Method is selected the Equi-Angular Shape method is used.
There are three other options for controlling the linking of strings:
Link Crossover Checking tlc
Link-crossover-switch
This automatically checks for a link that intersects another link. Any surface that would contain crossovers will not be created and a warning dialog is displayed.
Use Tag Strings uta
Use-tag-switch
This toggle controls whether the tag strings should be ignored when creating a link.
Wireframe Attributes from Strings
tsa
wf-attr-from-str-switch
If selected, the string attributes, including color, will be passed to the wireframe during linking.
Another command, important in the creation of links, is Point Separation (Wireframe | Linking | Point Separation) which inserts additional, temporary points along the strings being linked. The command opens a dialog for setting the maximum separation distance between the additional points.
This feature is useful for minimizing the creation of long, narrow triangles. The default value is 0, which is effectively “off”. Long narrow triangles can form an inefficient wireframe that does not match the data accurately.
Linking Options
Linking Types
The linking commands used can be found in the Wireframes | Linking menu.
Link Strings ls link-strings
A minimum of two strings must be loaded in the design window, this command will create the link between the strings.
Link Boundary lbo link-boundary
Links two strings together taking into account (not crossing) any boundary strings. A minimum of one boundary string is necessary. A boundary string is created using the new-string command the string must be snapped to a point on the same string at each end, line snapping is not acceptable. The boundary divides a string, to assist in creating a split wireframe.
Link to Line ll link-to-line
Links a string to a single line (not a closed string section). This is useful for “closing-off” wireframes.
Link Boundary to Line lbl link-boundary-to-line
Links a string to a line to close the wireframe effectively, but taking into account (not crossing) and boundary (bridge) strings.
Link Quad lq link-quad
Creates a wireframe link between two selected points on each string. The segment between the two points must be selected. Link Quad gives an alternative control to using tag strings and allows a link to be built in stages. Useful for complex wireframes.
End
Linking Options
There are also two “endlink” commands that may be used to link within a string (the string must not be open) this has the effect of closing a wireframe at the ends forming an enclosed volume. End link eli end-link
Links within a single string. End link Boundary elb end-link-boundary
Links within a string and takes into account (does not cross) any boundary strings.
Undo last link ull undo-last-link
Erases all triangles created during the last wireframing operation. This may be a link between two strings, an end link or the creation of a DTM.
Point separation nps dtm-new-point-separation
When creating a DTM it is possible to force Studio to add new points to improve the triangulation. This can be useful if some of the string data has long segment lengths which would create large triangles. By setting a separation distance greater than zero string segments are divided up into shorter segments of the set value for triangulation.
Note the new points are not inserted into the strings but are
incorporated into the wireframe. The string data is not changed using this command.
Tag Strings
Tag strings may be used to increase control over the linking process. They can define the points to be linked for the Link Strings
command, which is particularly useful when wireframing complex shapes. A tag string may contain any number of points but each one must be on a different string perimeter. It is also possible to link a single point on one perimeter to a number of different points on the second perimeter as shown below.
Create tag string tgs create-tag-string
Tag strings must be snapped to the strings to be wireframed, as an exact coordinate match is expected. To create a tag string use (wireframes-linking-create-tag-strings). The command “new-string” is not acceptable.
Set tag string colour taco tag-string-colour
The color number may be typed in or the logical color name
may be given, such as 'red'.
Use tags uta use-tag-switch
Tag strings will only be used if the Use tag strings option has been turned on in the menu or from the Wireframe Settings dialog
(Wireframes | Wireframe Settings). They can be used with any of the wireframe linking methods listed above. The tag strings that may be required for sub-optimal linking to achieve the required shape and avoid crossovers may be unnecessary for optimal linking.
Linking toolbar
Displays the wireframe toolbar
Link two outlines using attributes l3 link-outline-pair-attribute
Enables multiple strings with a common attribute to be linked together in a single action to create a wireframe.
Uses a common attribute from at least two strings to create wireframe surfaces within the area described by each string. If a string is not closed, a straight line will be drawn between the endpoints to complete a boundary. Before running the command select at least two strings with a common attribute.
Interactive DTM creation
The Interactive DTM Creation menu contains the commands for creating surface wireframes (c.f. solid wireframes).
Simple unfolded surfaces like topography or terrain surfaces can be modeled as Digital Terrain Models or DTMs. A DTM provides an exact triangulated surface model in which all the datum points are honored. To create a DTM a set of X, Y, Z data values which describe the surface are required. This might take the form of point surveys or contour strings depending on the source of the data. DTMs are a special type of wireframe model, the file structures of DTMs and wireframes are identical. Some wireframe commands are also used for DTMs, e.g. Write Wireframes is used to save all wireframes, including DTMs.
DTM settings
The DTM Settings option permits the setting of the key parameters for DTMs.
Use Selected Limit Strings tli dtm-limit-include-switch
The selected limits (inner or outer) will form part of the DTM.
Duplicate Point Checking tpc dtm-point-check-switch
Checks the data for duplicate points.
World Coordinates-Off for View Coords tcs dtm-coordinate-switch
This controls the plane in which the DTM is generated. The DTM will be created in plan view when on and, in screen view when off.
Make DTM md make-the-dtm
To create a DTM, a points file must be loaded into Studio first. The resultant DTM will honor any settings and limits that may have been set. A color must be selected to display the DTM.
Undo last DTM uld dtm-undo-last-link
Removes the links between the displayed points of the most recently created DTM.
Selecting Inner and Outer Limits
DTM generation may be constrained by closed strings defined as inner or outer limits of the DTM. Limits are created using New-String and must be displayed before the DTM is created. These can represent a two-dimensional outline of the required DTM or they may contain points that are required to make up part of the DTM. If a string represents a two-dimensional outline then only the X and Y coordinates can be used.
Select Outer Limit sol pick-outer-limit
Marks the outer boundary of the DTM even if points are displayed outside the limit. When a string is selected as an outer limit, it is displayed as a cyan string.
Select Inner limit sil pick-inner-limit
When a string is selected as an inner limit it is displayed as a green string. Several inner limit strings may be selected. If inner limit strings are being used, there must be an outer limit string.
Deselect One Limit dli deselect-limit
Removes one of the selected limit strings. Deselect All Limits dal deselect-all-limits
Removes all of the selected limit strings. Set Point Tolerance sto set-tolerance
Prevents triangles from being created with sides shorter than the value set for this tolerance.
Maximum Separation mse maximum-separation
Sets the maximum side length for any triangle.
New Point Separation nps dtm-new-point-separation
Adds new points to improve the triangulation. This is useful if string data has long segment lengths which can create a wireframe that does not match the data correctly. The separation distance is applied to any new points automatically created. The same separation for adjoining wireframe surfaces should be used so triangle edge lengths correspond at the intersection of the two wireframes.
DTM toolbar
Tools
Slice wireframe slw slice-wireframe
Displays the intersection of the wireframe with the view plane. To save the intersection use Convert slice to string and save to a string file.
Convert slice to string csl convert-wireframe-slice
Converts a slice or slices through a wireframe into a string or strings.
Generate multiple slices msl multiple-wireframe-slice
Generates slices through a wireframe at given interval, parallel to the view plane. There is the option to save the intersections as strings. Calculate volume wvo wireframe-volume
Reports the volume, above or below a DTM, or within a closed wireframe. A wireframe must be selected and the type of wireframe must be selected (closed or DTM) before the results are displayed in the output window.
Strings from intersections sfi wf-intersections
Creates new strings from the intersections of wireframe triangles, where two of more wireframes cross each other.
Hull to strings hts convert-wf-hull
Creates strings of the outline of the wireframe as it is displayed on screen. If more than one wireframe overlap, only one outline is generated incorporating the wireframes.
Edit attributes ewa edit-wireframe-attributes
The color and any user defined attribute of a wireframe can be changed to suit. Attribute values can be changed by clicking on the ATT button and using the up and down arrows to select the attribute to edit.
Unlink triangle
utr unlink-triangle
Erases a triangle after it is selected and confirmed. Save
wireframe before running command because it is not possible to
undo.
Unlink wireframe
uw unlink-wireframe
Erases a link between two strings after it is selected and
confirmed. Save wireframe before running command because it
is not possible to undo.
Boolean operations
Studio has several commands, under Wireframes | Boolean Operations, that allow the merging, intersection or splitting of wireframes.
Wireframes are selected according to the chosen selection method. It is important to verifythe selected wireframes prior to combing or splitting. This ensures that adjacency data has been generated for each wireframe.
Merge
wme wireframe-merge
Merge is a surface operation that splits two wireframes where their surfaces intersect. Merge can be used for both open and closed wireframes. After running, each surface is uniquely numbered, this allows individual surfaces to be erased using Erase | Wireframe Surface. Verify each wireframe before merging.
Examples
Intersecting a Pit Wireframe with a Topography Wireframe
The figure below includes a topography wireframe and a pit
wireframe. The wireframes share the same GROUP and SURFACE values so, to select them individually, the selection method has been set to Attributes.
Four surfaces are created by Merge and these are illustrated below.
Topo inside the pit
Pit Below topo
Pit above topo
Topo outside the pit
1. The pit above topography (Yellow) 2. The pit below topography (Brown)
3. The topography outside the pit (Light green) 4. The topography inside the pit (Dark green)
Each surface has a different SURFACE number, which makes it possible to erase a surface using Erase | Wireframe Surfaces.
Truncating an Orebody at a Fault
The wireframes below represent an orebody that is truncated by a fault. Merge can be used to truncate the orebody wireframe at the fault surface.
Merge requires each wireframe to be selected in turn; the order does not matter. It creates four separate surfaces:
1. The orebody to the left of the fault. 2. The orebody to the right of the fault. 3. The fault inside the orebody.
4. The fault outside the orebody.
The resulting surfaces have the same GROUP value but different SURFACE values.
Erase | Wireframe Surfaces can be used to erase any unwanted wireframe sections.
Union
wun wireframe-union
Union enables wireframes to be combined. The example below shows a newly discovered shoot (represented by the green wireframe slice), which is to be merged with the original wireframe model of the orebody (represented by the red wireframe slice).
The command prompts for each of the wireframes to be selected in turn. As with all merge and intersect commands, wireframe selection is controlled by the selection method.
Verify each wireframe before union. Make sure the wireframes and strings are saved before selecting union if an intersection string is to be created as above. If not other strings will be saved to the file, not just the intersection.
Intersection
win wireframe-intersection
Intersection is used to find the common volume of two overlapping wireframes. The resultant wireframe represents the overlap of the two selected wireframes as shown in the example below.
After Intersection
Difference
wdi wireframe-difference
Difference takes two overlapping wireframes and subtracts the second wireframe from the first.
A screen shot below is of two wireframes representing a stope with development. The second is a slice through the same wireframes. Difference is used to subtract the development wireframe from the stope wireframe. The stope wireframe is selected first.
Split
spli wireframe-split
Split isused to split a wireframe along the intersection of the selected wireframe(s) with the current view plane.
The following screen captures illustrate a wireframe before and after a Split. Edit | Attributes is used to color one half of the wireframe after it has been split.
After
Multiple split
mus multiple-wireframe-split
Multiple Split is used to split a wireframe at regular intervals parallel to the view plane. The interval used for splitting must be defined.
The following screen captures illustrate a wireframe before and after the Multiple Split. Multiple Split has been used to make it possible to delete a number of the resulting sections.
Solid hull soh wireframe-solid-hull
Solid operation to find the outer surface for overlapping wireframes. The result is the equivalent of performing wireframe-union
commands on the surfaces in the wireframe two at a time until all are merged into a single solid. The method differs from wireframe-union in that the wireframe-solid-hull command resolves the overlap in the selected wireframe.
Update DTM udt wireframe-surface-merge
This is used to update one surface wireframe with another. The new surface is generated using the second wireframe selected to update the surface elevation.
In the example shown below the Update DTM (Boolean Operations | Update DTM)command has been used to update an open cut pit by adding the new to the existing pit wireframe. The first screen capture shows a slice through the wireframe; different line colors have been
used to define the two wireframes.
The following screen captures show the resultant wireframe after the (Boolean Operations | Update DTM)has been run.
Project DTM to view pdv wireframe-surface-project
Project a wireframe surface to the viewplane to form a solid. The input wireframe should be open and single valued when viewed in the direction of the viewplane. The input wireframe may be several discrete surfaces
