isolines
The isolines module is used to produce lines of constant (iso)value on a 2D surface (such as a slice plane), or the external faces of a 3D surface, such as the external faces of a plume. The input data for isolines must be a surface (faces), it cannot be a volumetric data field. If the input is the faces of a 3D surface, then the isolines will actually be 3D in nature. Isolines can automatically place labels in the 2D or 3D isolines. By default isolines are on the surface (within it) and they have an elevated jitter level (1.0) to make them preferentially visible. However they can be offset to either side of the surface.
Ports
| Direction | Name | Type | Description |
|---|---|---|---|
| Input | Input Field | Field | The field used to generate contours. |
| Input | Input Contour levels | Contours | Contour level information. |
| Output | Output Field | Field | The field containing generated isolines. |
| Output | Output Contour levels | Contours | Contour level information. |
| Output | Output Object | Renderable | A renderable object displaying the grid created by the module. Note that this is output even when Allow Run is off. |
Properties
| Property | Type | Description |
|---|---|---|
| Allow Run | Boolean | This toggle can prevent the module from running. Allowing the user to make changes to large data sets without waiting for updates. |
| Execute | Button | The Execute button forces the module to run. If this has been pressed and the application saved, it will cause the module to run when the application is loaded. |
Isoline Settings
| Property | Type | Description |
|---|---|---|
| Isoline Component | Choice | The Isoline Component refers to the nodal data component that will be used to create isolines. |
| Min Max Linking | Choice: Link Min/Max, Recalculate from Data | The Min Max Linking control is used to set the linked values for the Minimum and Maximum Isoline levels. If the min and max values for the selected component have been changed, Recalculate can be used to find the actual min and max. |
| Isoline Generation Properties | Value generator | Generates the list of isoline levels. Methods: Per Log Decade (logarithmic spacing with a set number of isolines per decade), Linear By Step (values from an anchor point at a fixed step size), Linear By Count (a fixed number of evenly-spaced values), User Entries (manually specified values). |
| Surface Offset | Double | The Surface Offset controls where the isolines will be placed, vertically, in reference to the surface. |
| Offset Both Ways | Boolean | Offset Both Ways will enable creating isolines on both sides of a surface e.g. the top and bottom sides of a ground surface. |
Label Settings
| Property | Type | Description |
|---|---|---|
| Add Labels | Boolean | The Add Labels toggle specifies whether labels are added. |
| Flip Labels Horizontally | Boolean | The Flip Labels Horizontally toggle will flip all labels upside down. Depending on the viewpoint and the data, this may be useful for making the labels more readable. |
| Flip Labels Vertically | Boolean | The Flip Labels Vertically toggle will flip all labels to the other side of the surface. Depending on the viewpoint and the data, this may be useful for making the labels more readable. |
| Label Spacing | Double | The Label Spacing value. |
| Label Height | Double | The Label Height scales the size of each label. |
| Label Start | Double | The Label Start will offset the start of each label along the line. |
| Format Label Numbers | Number Formatting | The Format Label Numbers control allows the user to set how numbers that are turned into labels will be formatted. |
| Label Suffix | Choice: Use Data Units, User Specified, None | The Label Suffix is a string that is appended to each label. |
| User Suffix | String | If the User Specified option is selected in Label Suffix, the string can be set with this value. |
