VO Grids
Control the display of celestial and space grids in the 3D window
Syntax
VO <ScenarioPath> Grids {GridType} {DisplayOption} <Value>
Description
The VO Grids command allows you to control the display of celestial and space grids in the 3D window. {GridType} can be:
| {GridType} | Description |
|---|---|
| Celestial | Defines the display of right ascension and declination lines in the 3D Graphics window. |
| Space | Specifies the space grids that display in the 3D Graphics window. Space grids can aid in accurately interpreting distances between objects in space. |
If {GridType} is Celestial, valid {DisplayOption} <Value> combinations are:
| {DisplayOption} | <Value> | Description |
|---|---|---|
| Show | {On | Off} | Projects right ascension and declination lines onto a sphere surrounding the Earth. |
| Color | {Color} | The color of the grid lines. For valid {Color} options see Common Options. |
| ShowLabel | {On | Off} | Displays azimuth-elevation values display using the same color as the grid lines. |
| WindowID | <WinNumber> | The number of the window where you wish the grids to display. If not entered the first 3D Graphics window will be used. |
If {GridType} is Space, valid {DisplayOption} <Value> combinations are:
| {DisplayOption} | <Value> | Description |
|---|---|---|
| ShowECI | {On | Off} | For ECI Coordinates, the space grid displays along the equatorial plane in the Earth-Centered inertial coordinate system. |
| ECIColor | {Color} | The color of the ECI space grid lines. For valid {Color} options see Common Options. |
| ShowEcliptic | {On | Off} | Displays a space grid in the plane of the ecliptic. |
| EclipticColor | {Color} | The color of the ecliptic space grid lines. For valid {Color} options see Common Options. |
| ShowRadial | {On | Off} | Displays the space grid as radial lines originating from the center of the Earth. |
| ShowAnnotation | {On | Off} | Annotates the distance between grid points in the 3D Graphics window. |
| AnnotationSize | {Small | Medium | Large} | The text size for the annotations. |
| AnnotationColor | {Color} | The color of the ecliptic space grid lines. For valid {Color} options see Common Options. |
| AnnotationX | <XValue> | A real numbers between 0 and 10000.0 representing the X,Y location at which the annotations display, where (0,0) is defined as the lower left corner of the 3D Graphics window. |
| AnnotationY | <YValue> | |
| WindowID | <WinNumber> | The number of the window where you wish the grids to display. If not entered the first 3D Graphics window will be used. |
In order to see an Annotation, either ShowECI or ShowEcliptic must be turned On.
