Output

Use the Output tab of the form to configure the information that will be included in the generated model.

Full Lithology

Select the Full Lithology check box to configure the lithology to be output to the model.

Type

Double click or use the selection box in the Type field to set the lithology type for the model output.

Prefix

Optionally, enter the prefix for lithology information labels in the Prefix field.

Fault Blocks

Select the Fault Blocks check box to wireframe solid representing fault domains.

Type

Double click or use the selection box in the Type field to select the fault block type to be included.

Prefix

Optionally enter a prefix to be used for labelling model fault blocks in the Prefix field.

Clipped Fault Planes

If you select the Clipped Fault Planes check box, wireframes representing clipped fault surfaces will be produced.

Type

Use the Type field to select the clipped fault plane type to be included in the model.

Prefix

Enter a prefix to be used for clipped fault plane labels in the model.

Contact Surfaces

Select the Contact Surfaces check box to produce wireframes representing contact surfaces of your lithology units.

Type

Double click or use the Select button in the Type field to select a configured contact surface type.

Prefix

Enter an applicable Prefix for the contact surfaces data labels in the field.

The Contact Surfaces options on the Output tab of the Geology form

Topography

Select the Topography check box to produce a DTM of your topology. If you opted to use your own wireframe for topography and have this option enabled, a DTM of your provided wireframe will be clipped to the extents and saved.

Type

Double click or use the Select button in the Type field to select the topography type to be included.

Colour

Use the Colour box to select the colour to be used in rendering the included topography information in the model.

Settings

Global name prefix

If you enter a prefix in the Global Name Prefix field, it will be used on all labels for the model.

Quality

This setting provides a convenient way to control the quality and the speed of model generation. There are five quality settings: Draft, Standard, High, Ultra and Custom.

Setting the quality to Draft allows the general shape of the model to be generated quickly. Setting the Quality to Custom allows a user-specified error tolerance.

The Quality menu on the Output tab of the Geology Model form

Tolerance

With the exception of Custom, each quality setting has a pre-set error tolerance value. The error tolerance for Draft is approximately twice that for Standard, which, in turn, is twice that for High, etc.

If you have selected Custom quality, enter the Tolerance value in the field. There is no limit to the user-specified error tolerance value (and hence the minimum mesh size), other than that imposed by available system memory.

The surface extracted from the implicit model is done to the accuracy defined by the tolerance, such that the difference between the wireframe surface and the theoretically perfect mathematical model falls within the measured tolerance distance.

Max triangle size

To eliminate large meshes, specify a Maximum Triangle Size parameter in grid units.

By default, mesh size is controlled by the Tolerance parameter, which specifies the maximum error between the rendered surface and the actual surface. Typically, larger meshes are used where the surface is relatively flat, and smaller meshes are used where the surface has high curvature.

If a Max Triangle Size is specified, all triangles will be that size, or smaller if they fail the tolerance test.

Snap wireframe to input data

The generated wireframes may be slightly offset from the points they were created from. Select this check box to snap the wireframes to the input data. Snapping will move the closest triangle to each snap point, if the distance between the two is less than the specified Snap tolerance.

If you do not enter a value, the default tolerance is 1 metre.

Auto load

Select this option to load the generated output in Vizex. The default draw style for an auto-loaded wireframe is 3D Shaded.

Output settings on the Geology Model form

While the model generation process is performed, progress messages will be shown to indicate to the user how many lithologies have been modelled so far - e.g. Modelling Lithology XXX (1 of 5).

If faults are present, the progress messages also indicate which fault block is being modelled e.g. Fault Block (1 of 3).
