Inherits Renderable

Members

Name	Documentation	Type	Description	Optional
Color	This value determines the RGB main color for the lines and points of the trail	Color3	Value of type ‘Color3’	No
Format	A NORAD-style Two-Line element Orbit Mean-Elements Message in the KVN notation JPL’s Small Bodies Database The file format that is contained in the file	String	In list { TLE, OMM, SBDB }	No
Path	The file path to the data file to read	File	Value of type ‘File’	No
SegmentQuality	A segment quality value for the orbital trail. A value from 1 (lowest) to 10 (highest) that controls the number of line segments in the rendering of the orbital trail. This does not control the direct number of segments because these automatically increase according to the eccentricity of the orbit	Integer	Value of type ‘Integer’	No
ContiguousMode	If enabled, then the contiguous set of objects starting from StartRenderIdx of size RenderSize will be rendered. If disabled, then the number of objects defined by UpperLimit will rendered from an evenly dispersed sample of the full length of the data file.	Boolean	Value of type ‘Boolean’	Yes
LineWidth	This value specifies the line width of the trail if the selected rendering method includes lines. If the rendering mode is set to Points, this value is ignored	Double	Value of type ‘Double’	Yes
RenderSize	Number of objects to render sequentially from StartRenderIdx	Integer	Value of type ‘Integer’	Yes
StartRenderIdx	Index of object in renderable group to start rendering (all prior objects will be ignored)	Integer	Value of type ‘Integer’	Yes
TrailFade	This value determines how fast the trail fades and is an appearance property.	Double	Value of type ‘Double’	Yes

Name	Documentation	Type	Description	Optional
DimInAtmosphere	Enables/Disables if the object should be dimmed when the camera is in the sunny part of an atmosphere	Boolean	Value of type ‘Boolean’	Yes
Enabled	This setting determines whether this object will be visible or not	Boolean	Value of type ‘Boolean’	Yes
Opacity	This value determines the opacity of this renderable. A value of 0 means completely transparent	Double	In range: ( 0,1 )	Yes
RenderBinMode	This value specifies if the renderable should be rendered in the Background,Opaque, Pre/PostDeferredTransparency, or Overlay rendering step	String	In list { Background, Opaque, PreDeferredTransparent, PostDeferredTransparent, Overlay }	Yes
Tag	A single tag or a list of tags that this renderable will respond to when setting properties	Table, or String	Value of type ‘Table’, or Value of type ‘String’	Yes
Type	This tells the type of the renderable	String	Value of type ‘String’	Yes
