Inherits Renderable

Members

Name	Documentation	Type	Description	Optional
TextureSource	A directory containing images that are loaded from disk and used for texturing the sphere. The images are expected to be equirectangular projections.	Directory	Value of type ‘Directory’	No
BlendingOption	Controls the blending function used to calculate the colors of the sphere with respect to the opacity.	String	Value of type ‘String’	Yes
ColorMap	Color map / Transfer function to use if UseColorMap is enabled.	File	Value of type ‘File’	Yes
DisableDepth	If disabled, no depth values are taken into account for this sphere, meaning that depth values are neither written or tested against during the rendering. This can be useful for spheres that represent a background image.	Boolean	Value of type ‘Boolean’	Yes
DisableFadeInOut	Enables/Disables the fade in and out effects.	Boolean	Value of type ‘Boolean’	Yes
FadeInThreshold	The distance from the center of the Milky Way at which the sphere should start to fade in, given as a percentage of the size of the object. A value of zero means that no fading in will happen.	Double	Value of type ‘Double’	Yes
FadeOutThreshold	A threshold for when the sphere should start fading out, given as a percentage of how much of the sphere that is visible before the fading should start. A value of zero means that no fading out will happen.	Double	In range: ( 0,1 )	Yes
MirrorTexture	If true, mirror the texture along the x-axis.	Boolean	Value of type ‘Boolean’	Yes
Orientation	Specifies whether the texture is applied to the inside of the sphere, the outside of the sphere, or both.	String	In list { Outside, Inside, Both }	Yes
Segments	The number of segments that the sphere is split into.	Integer	Greater or equal to: 4	Yes
Size	The radius of the sphere in meters.	Double	Greater than: 0	Yes
UseColorMap	Used to toggle color map on or off for the sphere. Mainly used to transform grayscale textures from data into color images.	Boolean	Value of type ‘Boolean’	Yes

Inherited members from Renderable

Name	Documentation	Type	Description	Optional
DimInAtmosphere	Decides if the object should be dimmed (i.e. faded out) when the camera is in the sunny part of an atmosphere.	Boolean	Value of type ‘Boolean’	Yes
Enabled	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	A value that specifies if the renderable should be rendered in the Background, Opaque, Pre-/PostDeferredTransparency, Overlay, or Sticker rendering step.	String	In list { Background, Opaque, PreDeferredTransparent, Overlay, PostDeferredTransparent, Sticker }	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	The type of the renderable.	String	Value of type ‘String’	Yes
