Set the attributes of a 3D Graphics window
VO <ScenarioPath> Attributes {AttributeOption} <Parameters> [<WinNumber>]
The VO Attributes command allows you to set basic attributes for the 3D Graphics window.
If you don't specify a <WinNumber>, the window with the lowest scene ID number is used. If you specify a <WinNumber> that doesn't exist, Connect returns a NACK.
{AttributeOptions} and their associated <Parameters> are outlined in the following Table.
| {AttributeOption} | <Parameters> | Description |
|---|---|---|
| Clouds | {On | Off} | Turn on or off the display of cloud overlays on the central body being displayed in the 3D window. |
| File "<FileName>" | Specify a cloud filename. | |
| URI "<UriPath>" | Specify the uri file path to set a cloud file index. | |
| Altitude <Value> | Specify the altitude of the cloud layer in Connect distance units. Valid value must be greater than 1.0 meter. | |
| Roundness <Value> | Control the roundness of the clouds. Valid value is between 0.5 and 5.0. | |
| Auto | Automatically create .cld index file and download associated image files for the scenario time period. Use the newly created .cld file to display the cloud images. The files are downloaded to <stk user dir>/Downloads/Clouds. If the cloud file exists, it will not be downloaded again. |
To display clouds in the first 3D Graphics window:
VO * Attributes Clouds On 1
To set the altitude of the cloud layer to 3000 meters:
VO * Attributes Clouds Altitude 3000.0
To set the roundness of the clouds 0.75, in the second 3D Graphics window:
VO * Attributes Clouds Roundness 0.75 2
To display clouds from an external image file:
VO * Attributes Clouds URI "file:///C:/Documents and Settings/STK/Desktop/CloudsURIBak/cloudsTest.cld"
If activated, Connect returns an acknowledgement message.
