modify data 3d
The modify data 3d module provides the ability to interactively change data in 3D volumetric models. This is not a recommended practice since volumetric models created in EVS generally have underlying statistical measures of quality that will be meaningless if the data is modified in any way.
However, it is not unusual for a model to occasionally have regions where extrapolation artifacts cause shards of plumes to appear. This module provides a way to remove those.
The basic approach is to move the modification sphere to the problem region and set the size and shape of the ellipsoid before changing your data.
Note: This module does not modify the upstream data.
Ports
| Direction | Name | Type | Description |
|---|---|---|---|
| Input | Input Field | Field | The field containing the data to be modified. |
| Input | Z Scale | Number | The factor for vertical scaling. |
| Output | Output Field | Field | A field containing the field with modified data. |
| Output | SampleData | Renderable | A renderable object displaying the selected data. |
Properties
| Property | Type | Description |
|---|---|---|
| Transition Option | Choice: Linear, Non-Linear | The Transition Option control allows the user to select how the values are modified. Linear causes the weighting to be a straight line from the Inner Weighting value to zero at the outer change radius. Non-Linear is a smooth transition from the Inner Weighting value to zero at the outer change radius. |
| Anisotropy | Double | The Anisotropy is the ratio of the change radius in the x-y plane to the vertical (z) direction for undistorted coordinates. |
| Pre Altered Z Scale | Double | Pre-Altered Z Scaling is the z-exaggeration you are using for display purposes. |
| Create Output Field | Button | Create Modified Output Field button causes the modified data to be output. |
Modification Settings
| Property | Type | Description |
|---|---|---|
| X Center | Double | The X Center slider controls the center of the change sphere. |
| Y Center | Double | The Y Center slider controls the center of the change sphere. |
| Z Center | Double | The Z Center slider controls the center of the change sphere. |
| Glyph Display Radius | Double | Glyph Display Radius is the size (in your units) of the spherical glyph that identifies the center modification location. |
| Modification Value | Double | The Modification Value is the value to change (clamp) the data set. |
| Inner Weighting | Double | The Inner Weighting is the constant value over the inner change radius. |
| Inner Change Radius | Double | The Inner Change Radius is the radius in the x-y plane of the region affected at the constant Inner Weighting. |
| Outer Change Radius | Double | The Outer Change Radius is the radius in the x-y plane of the total region affected. |
