Public Member Functions
override List< int >	Init ()
	Initialize the objects for this display controller. This is called by GSController init as part of its Start()
override Vector3	MapToScene (Vector3 rWorldAbs, double time)
	Intended to only be called for the body being launched!
Public Member Functions inherited from GravityEngine2.GSDisplay
void	ActiveSet (bool value)
	Change the active status.
void	DisplayBodyRemoveByBodyId (int id)
	Remove all GSDisplayObjects with the given bodyId.
delegate void	DisplayInScene (GECore ge, MapToSceneFn mapToScene, double timeWorld, bool alwaysUpdate=false)
void	DisplayObjectAdd (GSDisplayObject gdo)
	Add a GSDisplayObject (typically a GSDisplayBody or GSDisplayOrbit). Different display objects may have different update methods or choose to register custom display functions so they are asked to "add themselves" via AddToSceneDisplay(). As part of this they must call RegisterDisplayObject() [which is where the "book-keeping" is done.].
void	DisplayObjectRemove (GSDisplayObject gdo)
	Remove a GSDisplayObject (e.g. GSDisplayBody, GSDisplayOrbit etc.)
virtual void	DisplayUpdate (GECore ge, double elapsedWorldTime)
	Main update loop for display of bodies and orbits in the scene. (Internal)

int	RegisterDisplayObject (GSDisplayObject gdo, int bodyId, Transform transform=null, DisplayInScene displayInScene=null, bool trajectory=false, LineRenderer trajLine=null)
void	UpdateDisplayObjectBody (long displayId, int bodyId)
	Update the internal state of GSDisplayObject. Can be used to designate a new bodyId to track.

Protected Member Functions
override void	DisplayUpdateInit (GECore ge, double elapsedWorldTime)
override void	TrajectoryUpdate (GECore geTrajectory)
	In a map display need to thread the trajectory under the map when we wrap off the edge (either horizontally or vertically). In this case we need to add more than one point for a given traj. point, hence the need to override the entire traj. update.

Additional Inherited Members
Public Types inherited from GravityEngine2.GSDisplay
enum	AddMode { CHILDREN , LIST , SCENE }
	Mode the controller will use to find GSBody objects to add CHILDREN: Scan all children of this controller for GSBody LIST: Add objects explicitly listed SCENE: Find all objects in the scene with GSBody components.
enum	DisplayMode { DIRECT , INTERPOLATE }

Detailed Description

Display objects and trajectories on XY plot of ascent/launch path.

This display is focused on the ascent of a single GSBody with respect to a planet in a given orbital plane.

NOTE: to have the usual Cartesian X, Y plane need to have the camera located at -Z looking toward the origin, since Unity has a LH coordinate system.

Member Function Documentation

DisplayUpdateInit()

override void GravityEngine2.GSLaunchDisplay.DisplayUpdateInit ( GECore ge, double elapsedWorldTime )

protectedvirtual

Parameters

ge
elapsedWorldTime

Reimplemented from GravityEngine2.GSDisplay.

Init()

override List< int > GravityEngine2.GSLaunchDisplay.Init ( )

virtual

Initialize the objects for this display controller. This is called by GSController init as part of its Start()

• find the GSDisplayObject implementations (mostly GSDisplayBody)
• find the GSDisplayOrbit
• arrange internal data structure by having above objects register with this class
• determine if any bodies want trajectory recording and pass their ids back

Returns

List of trajectories

Reimplemented from GravityEngine2.GSDisplay.

MapToScene()

override Vector3 GravityEngine2.GSLaunchDisplay.MapToScene ( Vector3 rWorldAbs, double time )

virtual

Intended to only be called for the body being launched!

Parameters

rWorldAbs
time

Returns

Reimplemented from GravityEngine2.GSDisplay.

TrajectoryUpdate()

override void GravityEngine2.GSLaunchDisplay.TrajectoryUpdate ( GECore geTrajectory )

protectedvirtual

In a map display need to thread the trajectory under the map when we wrap off the edge (either horizontally or vertically). In this case we need to add more than one point for a given traj. point, hence the need to override the entire traj. update.

Since this is the only use case, C&P the common code for now.

Parameters

geTrajectory

Reimplemented from GravityEngine2.GSDisplay.
