Method Detail

init

public void init()

Initialisation

Overrides:

init in class PjProject

update

public boolean update(java.lang.Object event)

Update the class whenever a child has changed. Method is usually invoked from the children.

Overrides:

update in class PsObject

Following copied from interface: jv.object.PsUpdateIf

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

See Also:

PsObject, PsUpdateIf.getFather(), PsUpdateIf.setParent(PsUpdateIf)

restoreGeometry

public boolean restoreGeometry()

Restore the saved vertices of the geometry to its original shape. Method is only available in interactive mode.

Returns:

true if vertices were restored successfully

getGeometry

public PgGeometryIf getGeometry()

Get geometry used for evolution.

Overrides:

getGeometry in class PjProject

Following copied from class: jv.project.PjProject

See Also:

PjProject.selectGeometry(PgGeometryIf)

setGeometry

public PgPointSet setGeometry(PgPointSet geom)

Set geometry used for evolution.

getDirection

public int getDirection()

Get direction used for evolution. Possible values are static variables of this class with name prefix OFFSET_.

setDirection

public int setDirection(int dir)

Set direction used for evolution. Possible values are static variables of this class with name prefix OFFSET_.

evolve

public void evolve()

Evolve point set in direction of a vector field.

Parameters:

dir - type of vector field used as evolution direction

geom - geometry to evolve

dist - dist*vector determines the length of the translation vector

setTime

public boolean setTime(PsTimeEvent time)

Compute evolution.

Overrides:

setTime in class PjProject

start

public void start()

Create a new animation and start it.

Overrides:

start in class PjProject

Following copied from class: jv.project.PjProject

See Also:

PvViewerIf.start(), #isEnabledAutoFit(boolean)

stop

public void stop()

Stop the animation.

Overrides:

stop in class PjProject

Following copied from class: jv.project.PjProject

See Also:

PvViewerIf.stop()
