create stratigraphic hierarchy
The create stratigraphic hierarchy module reads a pregeology file (.pgf) and allows the user to interactively build geologic surfaces based on the input file’s geologic surface intersections. This process is carried out visually in the EVS viewer using the module’s user interface. The surface hierarchy can be generated automatically for simple geology models or layer-by-layer for complex models. When the user is finished creating surfaces, the GMF file can be finalized and converted into a .GEO file.
Ports
| Direction | Name | Type | Description |
|---|---|---|---|
| Output | Geologic Legend Information | Geology Legend | Information required to properly label stratigraphic output or lithology within Legend. |
| Output | Output Objects | Renderable | A renderable object displaying the TIN surface and the pregeology data. |
Properties
| Property | Type | Description |
|---|---|---|
| Filename | String | The name of the pregeology file. |
| Z Scale | Double | The vertical exaggeration to be applied to the output object. |
| Existing GMF Filename | String | The name of an existing GMF. This file will be loaded and the surfaces added to the current hierarchy being created. |
| Current GMF Filename | String | The name of the current GMF being created. This file can be overwritten or appended to each time the Write Surface button is pressed. |
| Overwrite GMF File | Boolean | Causes the Current GMF file used while creating the hierarchy to be overwritten when the Write Layer button is selected. On by default but automatically turned off when using an Existing GMF Filename, or after the Write Layer button is selected. |
| Preserve Bottom | Boolean | When selected, the places where the TIN has reached the bottom of the boring will not be dropped. |
| Samples | Boolean | Prevents or allows samples from being created or displayed. |
| Screens | Boolean | Prevents or allows screens from being created or displayed. |
| Well Labels | Boolean | Prevents or allows well labels from being created or displayed. |
| Sample Labels | Boolean | Prevents or allows sample labels from being created or displayed. |
Geologic Hiearchy Options
| Property | Type | Description |
|---|---|---|
| Current Material List | Choice | Shows every material that intersects the current surface. |
| Layer Thickness | Double | Controls the thickness of the current layer. Enabled when the Method is set to Layer Thickness. |
| Set To Max Thickness | Button | Forces the current Layer Thickness to its maximum extent. Saves the user from having to drag the slider each time. |
| Write Surface | Button | Writes the position of every boring in the TIN surface and the current selected material to the GMF file. If the Overwrite toggle is on, it overwrites the current file; otherwise it appends the surface. Surfaces at the bottom of a material may add the material below to the current selected material list. If the surface is at the bottom of the boring, that boring is removed from the TIN surface. |
| Undo Surface | Button | Removes the last surface from the file. Affects file contents, not just the memory-resident surface. |
| Finish Geology | Button | Used when the GMF file is complete. Converts the GMF to a GEO file. |
| Cycle | Boolean | Causes the module to automatically generate layers using the set parameters until it reaches a stopping condition (such as reaching the bottom of the model or producing a layer of the same material as the one above). |
Picked Data
| Property | Type | Description |
|---|---|---|
| Picked Boring | String | The currently selected boring. |
| Boring State | Choice: Normal, Locked, Preserved, To Be Dropped, Boring Dropped | Describes the action being taken on the currently picked boring. Normal allows the surface to move along the boring; Locked prevents movement; Preserved is used with the Preserve Bottom toggle; To Be Dropped indicates the end of the boring has been reached; Boring Dropped means the boring has been dropped from remaining surfaces. |
| Offset | Double | Applied to the current position of the picked boring, allowing user control of a single point in the TIN. |
Group Select
| Property | Type | Description |
|---|---|---|
| Show Group Select Window | Boolean | Allows the user to select multiple borings at once and to change their state. |
| Zoom To Fit | Button | Resets the scaling for the group select window. |
| Set Group To Locked | Button | The borings contained within the drawn polyline will have the state changed to the Locked position. |
| Set Group To Normal | Button | The borings contained within the drawn polyline will have the state changed to the Normal position. |
| Erase Last Point | Button | The last point drawn in the selection polyline will be removed. |
| Clear All Points | Button | All points in the selection polyline will be removed. |
Sample Settings
| Property | Type | Description |
|---|---|---|
| Sphere Count Limit | Integer | The maximum number of spheres to create. If the number of samples exceeds this value, the module will generate colored tubes instead. |
| Maximum Sample Threshold | Integer | The maximum number of samples from the input file to allow. If the file contains more than this amount, an error will occur. |
Glyph Settings
| Property | Type | Description |
|---|---|---|
| Glyph Size | Double | Used to scale the glyphs in all directions. The default is automatically computed based on input data. |
| Priority | Choice: Maximum, Minimum | Reverses the scaling so that the smallest sample values have the largest size. |
| Minimum Scale Factor | Double | Scales the sample values with the least Priority. |
| Maximum Scale Factor | Double | Scales the sample values with the greatest Priority. |
| Sphere Subdivisions | Integer | Defines how finely the sample spheres are rendered. Higher values mean smoother spheres but at a higher memory cost. |
Screen Settings
| Property | Type | Description |
|---|---|---|
| Display Screens As | Choice: Tubes, Wires | Controls how the well screens will be displayed. Tubes display as a tube from the top to the bottom of the well screen; Wires display as a line. |
| Screen Ratio | Double | A percentage value (0.0 to 100.0) that sets what proportion of the Glyph Size the tube size will be. |
| Screen Tube Resolution | Integer | The number of divisions used to make each well screen tube. The higher the resolution, the smoother each tube will be. |
| Close Screen Tubes | Boolean | Places a disc inside the top and bottom of the tube for a more solid visualization. |
| Connect Screen Lines | Boolean | For non-vertical intervals, merges separate cell ends into a single seamless tube by averaging the separate ends. |
Label Settings
| Property | Type | Description |
|---|---|---|
| Title | String | Sets the template the title labels are generated with. |
| Title Position | Choice: Top of Boring, Bottom of Boring, Top and Bottom | Allows the user to place the title label at the top or bottom of the boring. |
| Default Top | Choice: First Sample, Tube Top | If the ground elevation is not defined in file, sets the default to either the first sample or the Boring Tube Top value. |
| Tube Top | Double | The top elevation for each tube. If specified in the file, the file value is used instead. |
| Features | String | Sets the template the feature labels are generated with. |
| Screen Labeling | Choice: At sample, At mid-interval | Specifies where each feature label will occur. |
| Label Type | Choice: Forward Facing Fonts, TrueType Fonts, Line Fonts | Selects between three font types. Forward Facing Fonts are aligned to the View. TrueType fonts are standard fonts. Line fonts are low-impact fonts which perform better when large numbers of labels are generated. |
| True Type Font Style | Font | Allows the user to alter the basic look of the TrueType font. |
| 3D Label Settings | Label Settings | Allows the user to align the labels to an appropriate view. |
| Forward Facing Style | Font | Allows the user to align forward-facing labels and alter the basic layout of the font. |
| Label Color | Color | Sets the color for every label. |
| Top Offset | Double | The title (well/boring ID label) offset in the z direction. Raises or lowers your title and is added to the Z offset to determine the z location of the title. |
| Radial Offset | Double | The radial offset that determines how far from the sample to place the label. A value of 1 means to add the size of the sphere to the XYZ location of the sample and place the label there. |
| Label Angle | Double | Determines where in a circle around the sample to place the label. A value of zero places the label to the direct right of the sample; 90 places it directly above. |
| Z Offset | Double | Added to the Z coordinate to raise or lower the labels in the Z direction. |
| Label Subsetting | Choice: None, Blank Labels, Boring Min/Max | Restricts the number of labels in a rectangular region by using label blanking, or restricts the number along a boring based on analytical value. |
| X Blank | Double | Helps create a 3D box that allows only the label at the highest or lowest value to be displayed inside (X dimension). |
| Y Blank | Double | Helps create a 3D box that allows only the label at the highest or lowest value to be displayed inside (Y dimension). |
| Z Blank | Double | Helps create a 3D box that allows only the label at the highest or lowest value to be displayed inside (Z dimension). |
| Favor Min Value | Boolean | Used along with the X, Y, and Z Blanking fields. Switches the behavior to display the lowest value inside the box. |
