opacity by nodal data
opacity by nodal data provides a means to adjust the opacity (1 - transparency) of any object based on its data values using a simple ramp function which assigns a starting opacity to values less than or equal to the Level Start and an ending opacity to values greater than or equal to the Level End. The appearance of the resulting output is often similar in appearance to volume rendering. opacity by nodal data converts data into partially transparent surfaces where data values at each point in a grid are represented by a particular color and opacity.
NOTE: Any module connected after opacity by nodal data MUST have Normals Generation set to Vertex (if there is a Normals Generation toggle on the module’s panel, it must be OFF).
Ports
| Direction | Name | Type | Description |
|---|---|---|---|
| Input | Input Field | Field | The field to use for adjusting opacity. |
| Output | Output Field | Field | The field with the new Opacity data. |
| Output | Output Object | Renderable | A renderable object to display. |
Properties
| Property | Type | Description |
|---|---|---|
| Allow Run | Boolean | The Allow Run Toggle will prevent the module from running. This allows the user to make multiple changes without the module constantly updating. |
| Execute | Button | The Run Once button will cause the module to run one time even if the Allow Run toggle has been turned off. |
| Component | Choice | The Component value allows the user to select which data component to use when setting the opacity. |
| Opacity Ramp Start | Double | The Opacity Ramp Start is the starting level of opacity to use in creating the output. A value of 0 is considered completely transparent, a value of 100 is completely opaque. |
| Level Start | Double | The Level Start is the lower range of the data to begin changing the opacity. Any value below this will be set to the Opacity Ramp Start value. |
| Opacity Ramp End | Double | The Opacity Ramp End is the ending level of opacity to use in creating the output. A value of 0.0 is considered completely transparent, a value of 100 is completely opaque. |
| Level End | Double | The Level End is the upper range of the data to begin changing the opacity. Any value above this will be set to the Opacity Ramp End value. |
| Non Linear | Boolean | The NonLinear toggle will cause lower values to have lower opacity while higher values will change the opacity more. |
