Visualizing Vector Fields of Anisotropy
You can examine computed vector fields of anisotropy in the 3D view of the workspace. Basic information about the selected vector field, as well as settings for adjusting visualizations, are available in the Data Properties and Settings panel, shown below.
Vector field properties and settings
| Description | |
|---|---|
| Information | |
| Name | Indicates the name of the selected vector field. |
| Number of vertices | Indicates the total number of vertices in the computed surface mesh. |
| X size | Indicates the dimension of the selected vector field in the X axis. |
| Y size | Indicates the dimension of the selected vector field in the Y axis. |
| Z size | Indicates the dimension of the selected vector field in the Z axis. |
| Vector field settings | |
| Show arrow head | If selected, arrow heads will appear on each vector in the field. |
| Use direction as color |
If selected, each Euclidean vector will be colored according to its orientation — X in red, Y in green, and Z in blue.
If not selected, each Euclidean vector will be colored according to the anisotropy value computed in the output anisotropy dataset. Coloring is selectable in the LUT drop-down menu. |
| Center at origin | If selected, each Euclidean vector will be centered at its point of origin. |
| Normalized modulus | If selected, the length of each directed line segment will be equal, regardless its magnitude. |
| Length slider | Lets you adjust the length of the Euclidean vectors in the selected vector field. |
| LUT |
Lets you select the colors that will be applied to mapped anisotropy values.
Note This option is not available whenever the Use direction as color option is selected. |
| Selected range (%) | Lets you threshold the minimum and maximum values that are displayed. |
| Clip | |
| The tools in the Clip box let you clip the selected vector field interactively along orthogonal or oblique planes in 3D views (see Clip Tool). | |
- Select a 3D view in the workspace.
- Select the required vector field in the Data Properties and Settings panel.
Information and settings related to the selected vector field appear in the Data Properties and Settings panel.
- Make the vector field visible by clicking the Eye and 3D icons.
The vector field appears in the 3D view at the default settings, in which each vector is colored according to the computed anisotropy value.
- Adjust the settings in the Vector field settings box, as required.
- You can uncheck the Show arrow head option to improve the visibility of the vectors in the field.
- You can adjust the length of the vectors, as well as select a different color mapping scheme in the LUT drop-down menu.
- You can threshold the minimum and maximum values that are displayed with the Range sliders or by entered new values in the Min and Max range boxes.
- You can color each vector according to its orientation by checking the Use direction as color option. If this option is selected, vectors oriented in the X axis will be colored red, vectors oriented in the Y axis will be colored green, and those oriented in the Z axis will be colored blue.
- Apply clipping, if required (see Clip Tool).
To clip a vector field, click the Clip
tool on the Clip panel and then do the following:- Drag a face of the Clip box to move a plane up and down or in and out. Each plane of the 6 sides of the parallelogram can be moved independently.
- Drag any of the control points to rotate a side of the parallelogram.
- Translate the Clip box by dragging from the central control point.
- Drag a face of the Clip box to move a plane up and down or in and out. Each plane of the 6 sides of the parallelogram can be moved independently.
