Volume to Wireframe

On the File tab, in the Convert group: Select Volume | To Wireframe to generate a wireframe from a 3D Volume isosurface.

In Vizex, when a 3D Volume layer is the active layer and an Isosurface is selected, you can also right-click and select Convert to Wireframe.

Input Data

File

Volume file

Double-click (or click on the Select icon) to select the Volume (*.mmvol ) file to be loaded. This file is an output from the File | Import | 3D Seismic (SEG-Y) function.

Colour field

Specify the name of a field which contains the values that will be used to colour-code the display. If you are mapping Colour field values to a Colour Set, the values in the Colour field must be valid RGB, HTML Hex, Hex, or Integer colour definitions.

Format Example
RGB 89,169,215 RGB ordered
HTML Hex #59A9D7 BGR ordered
Hex 0x59a9d7 BGR ordered
Int 5876183 BGR ordered: RED + (GREEN*256) + (BLUE*65536)

You can choose to select colour values directly from the Colour field without selecting a Colour set. In this case, you can also select a formatted Colour field.

You can view and edit the RGB values assigned to the Colour field in the Property Window. Click on the ellipsis to open the Colour picker:

Isosurface value

Use the Isosurface value field to define the value of the isosurface to be extracted from the Volume file.

Default value

Optionally, enter a default value to allow null cells to be replaced by the specified colour. The value you enter must be a valid RGB, HTML Hex, Hex, or Integer colour value.

Colour set

To map values in the Colour field to the colour values in a Colour set, double click (F3) to select the set that will be used to control the display colour. Right-click (F4) to create or edit a Colour set.

Default colour

Double-click (F3) to select the colour that will be used when a Colour field or a Colour set is not defined - or when a value in the Colour field is either not valid or is not mapped in the Colour set.

Build Options

Simplify wireframe

Select this option to reduce the number of vertices in the triangulation by eliminating those points that can be removed without causing the triangulation to move by more than the specified tolerance values:

  • Planar Tolerance. This is the maximum amount that the triangulation is allowed to move in any direction after vertices are removed.
  • If no planar tolerance is specified, a default value of 0.01 will be applied automatically. Specifying a large planar tolerance will significantly alter the nature of the triangulation.

Discard volumes less than

If this option is selected, all independent triangle shells with a volume less than the specified minimum volume will be removed.

Any value less than or equal to zero will disable volume removal.

Samples per cell

The default value for Samples per cell is Auto, which attempts to construct a wireframe with 2 samples per cell and keeps halving this value, to a minimum of 0.125, until it succeeds. If required, you can enter a value in the field.

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

Type and Name

Double-click (F3) to select the Type and Name of the output wireframe. A Type and a Name default are mandatory. A Name field may also be specified.

Auto load

Select the check box to automatically display the wireframe in Vizex when complete.

Forms

Click the Forms button to select and open a saved form set, or if a form set has been loaded, save the current form set.

By design, the Forms button is not available for loaded Vizex layers (i.e. when opening the form set properties of a layer in the Vizex Layer Display pane). In Vizex, the Forms button is only available for new forms opened via the Home tab or the Vizex tab, in the Layer group (or by double-clicking on a form type node in the Vizex Layer Types pane).

Save and Save As

Click the Save button to save the changes you have made to the form set. Click Save As to save your changes as a new form set. Save As will default to the first available form set number.

Reset

Click Reset to clear the form of all values and reset the form to its default state.

Reset Tab

For tabbed forms, select Reset Tab to clear the active tab of all values and reset the tab to its default state - without making any changes to other tabs in the dialog.

Undo and Redo

Click Undo (CTRL + Z) to undo recent changes in the form. After an Undo, click Redo (CTRL + Y) to restore the last change that was undone.

Collapse

Collapse (roll-up) the form to preview a chart, or preview the results of an operation in Vizex, or obtain input values from Vizex, the Property Window, the File Editor, or the Plot Editor.
