RenderableSolarImageryProjection

Inherits Renderable

A RenderableSolarImageryProjection projects solar observations from spacecraft instruments onto the surface of the Sun. The renderable uses one or more RenderableSolarImagery nodes as input and maps their imagery onto a solar sphere from the observing spacecraft’s perspective.

Each dependent RenderableSolarImagery provides the image texture, spacecraft position, and viewing geometry needed for the projection. This allows imagery captured from different spacecraft and instruments (e.g., SDO or STEREO) to be visualized directly on the Sun simultaneously.

Multiple observatories can be projected at once, allowing solar features observed from different viewpoints to be compared on the solar surface.

Members

Name	Documentation	Type	Description	Optional
DependentNodes	List of scene graph node identifiers that reference RenderableSolarImagery nodes. The imagery from these nodes is projected onto the solar surface from the perspective of the observing spacecraft.	Table	Table parameters	No
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
