Field Detail

m_geom

protected PgPointSet m_geom

Current geometry to be evolved. Some methods store the vertex array of the geometry to allow restauration of the original shape.

m_direction

protected int m_direction

Type of evolution direction. Possible values are static variables of this class with name prefix OFFSET_.

m_offsetFactor

protected PuDouble m_offsetFactor

Factor to move the vertices along the given vector. Note, the length of the vector is multiplied with this scalar value to compute the actual translation vector.

m_vertexSave

protected PdVector[] m_vertexSave

Array with saved vertices of current geometry. If evolution is cancelled then this data is used to restore the vertices.

m_bUpdateSender

protected boolean m_bUpdateSender

Flag determines if current update sequence has been issued from within this class.

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:

Overrides:

start in class PjProject

Following copied from class: jv.project.PjProject

See Also:

PvViewerIf.start(), #isEnabledAutoFit(boolean)

stop

public void stop()
