Constructor Detail

PwGeodesicFlow

public PwGeodesicFlow()

Creates a new instance of PwGeodesicFlow

Method Detail

init

public void init()

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjWorkshop

ok

public void ok()

Accept current version of the geometry as new version. Close workshop. The copy of the original geometry is ignored.

Overrides:

ok in class PjWorkshop

cancel

public void cancel()

Cancel operation of this workshop by resetting the assigned geometry, and finally close this workshop.

If necessary, the duplicate of the original geometry is restored into the geometry. The update method of the geometry is called.

Overrides:

cancel in class PjWorkshop

setDisplay

public void setDisplay(PvDisplayIf display)

Set the active display when this workshop was launched.

Specified by:

setDisplay in interface PjWorkshopIf

Overrides:

setDisplay in class PjWorkshop

pickInitial

public void pickInitial(PvPickEvent pos)

Sets the spawn point, starts the animation.

Specified by:

pickInitial in interface PvPickListenerIf

Parameters:

pos - new spawn point

See Also:

PvPickListenerIf

initialize

public int initialize()

Sets initial values for the particles.

Returns:

number of initialized particles

setTime

public boolean setTime(PsTimeEvent timeEvent)

Moves the particles one step forward.

Specified by:

setTime in interface PsTimeListenerIf

Parameters:

timeEvent - ignored

Returns:

super.update(this)

setAnimation

public void setAnimation(PsAnimation anAnimation)

Description copied from interface: PsTimeListenerIf

Assign the animation manager where this listener is registered. This method is invoked by the animation manager during registration of this listener, and usually is not required to be called by a user. If this listener has an assigned animation manager, then its animation panel may be shown to change the current time of this listener.

Only one animation manager may be assigned to this listener. Subsequent assignments will replace the previous assignment.

Specified by:

setAnimation in interface PsTimeListenerIf

See Also:

PsTimeListenerIf.getAnimation(), PsTimeListenerIf.hasAnimation()

hasAnimation

public boolean hasAnimation()

Description copied from interface: PsTimeListenerIf

Check whether this object is registered as listener of an animation manager.

Specified by:

hasAnimation in interface PsTimeListenerIf

See Also:

PsTimeListenerIf.getAnimation(), PsTimeListenerIf.setAnimation(PsAnimation)

getAnimation

public PsAnimation getAnimation()

Description copied from interface: PsTimeListenerIf

Get the animation manager where this listener is registered. This listener may only have a single animation manager which is assigned by the animation manager when this listener is registered using setAnimation(PsAnimation).

Specified by:

getAnimation in interface PsTimeListenerIf

See Also:

PsTimeListenerIf.hasAnimation(), PsTimeListenerIf.setAnimation(PsAnimation)

markVertices

public void markVertices(PvPickEvent event)

vector - 3d coordinates of vertex position

dragDisplay

public void dragDisplay(PvPickEvent event)

Sets the speed of the particles.

Parameters:

speed - the speed of the particles

update

public boolean update(java.lang.Object event)

Updates the geometry if this workshop has changed, i.e. if the event is this or null. Also propagates update() to superclass with the original argument event.

Some subclasses may register themselves as update listener of the geometry of this workshop. In order to prevent an update loop, this method safely uses isUpdateSender() when updating the geometry.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PjWorkshop

Parameters:

event - sender of this update.

Returns:

true if update was correctly handled by superclass.
