Adds a node that create a 'Stellar Body' from its members
Inputs
| Type | Name | Description |
|---|---|---|
| real | Color Index | Star Color Index, also named B-V |
| linearcolor | Color | Star RGB Color - Can be computed from the B-V value if the star is from an official Catalog |
| integer | Hipparcos Catalog ID | Star Hipparcos ID if present in the Hipparcos Catalog |
| integer | Henry Draper Catalog ID | Star Henry Draper ID if present in the Henry Draper Catalog |
| integer | Yale Bright Star Catalog ID | Star YaleBrightStar ID if present in the Yale Bright Star Catalog |
| string | Name | The Body Name |
| enum | Orbit Type | One of the predefined Orbit types (Solar system planets), any custom one for fantasy planets |
| real | Right Ascension J2000 | The Body J2000 Right Ascension (topocentric, from observer lat/lon) - In hours!Note: The "true" catalog J2000 is always geocentric;We decided to express this value in the topocentric variant for validation against JPL Horizons or Stellarium, which use data generated with a surface observer. |
| real | Declination J2000 | The Body J2000 Declination (topocentric, from observer lat/lon) - In DegreesNote: The "true" catalog J2000 is always geocentric;We decided to express this value in the topocentric variant for validation against JPL Horizons or Stellarium, which use data generated with a surface observer. |
| real | RA | The Body Right Ascension of date (topocentric, from observer lat/lon) |
| real | DEC | The Body Declination of date (topocentric, from observer lat/lon) |
| real | RAGeocentric | The Body Right Ascension of date (geocentric) - used for 3D scene placement. In hours. |
| real | DECGeocentric | The Body Declination of date (geocentric) - used for 3D scene placement. In Degrees. |
| real | Distance In AU | The Body distance to Earth - In Astronomical Units! |
| real | Radius | The Body Radius in Kilometers |
| real | Magnitude | The Magnitude of the Body seen from Earth |
| transform | UELocal Transform | Keep track of the Vault-relative transform, at ToD = 0 for animated bodies (Moon) |
| vector | Direction Toward Earth | Keep track of the location toward the Earth |
