public class PjVectorField

extends PjImportModel

implements java.lang.Runnable, java.awt.event.ActionListener

Project Vector Field Visualization and Geodesic Runge-Kutta uses PjImportModel to load models from file. Various models may be loaded and are extended by a (more or less) random tangential vector field.

Constructor Detail

PjVectorField

public PjVectorField()

If (this.instanceOf("PjVectorField")) it calls init-method.

Method Detail

init

public void init()

Description copied from class: PjProject

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 PjImportModel

start

public void start()

Description copied from class: PjImportModel

Load geometry file if file name has been specified. Otherwise do nothing.

Overrides:

start in class PjImportModel

Following copied from class: jv.project.PjProject

See Also:

PvViewerIf.start(), #isEnabledAutoFit(boolean)

update

public boolean update(java.lang.Object event)

Description copied from interface: PsUpdateIf

Event handling method in the update mechanism. Events not handled will be passed to m_parent or super in this sequence.

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)

setMethod

public void setMethod(int method)

Sets method used in calculateRepresentations.

See Also:

PROJECTION, GEODESIC, GEODESIC2, GEODESIC3

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent event)

Starts a new thread that calculates the LIC texture.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

See Also:

run()

calculateVectorField

public void calculateVectorField()

Calculates (pseudo) random vector field.

calculateRepresentations

public void calculateRepresentations()

Calculates the representations of vectors at every vertexstar. If current method in m_method is GEODESIC3,i.e. continous geodesic translation, this calculation is done in the runge-kutta class.

See Also:

PnTranslationRK, PwBary.getGeodRepresentation(jv.geom.PgElementSet, int, jv.vecmath.PdBaryDir, int, jv.vecmath.PiVector, jv.vecmath.PiVector), PwBary.getTransRepresentation(jv.geom.PgElementSet, int, jv.vecmath.PdBaryDir, int, jv.vecmath.PiVector, jv.vecmath.PiVector), PwBary.getProjRepresentation(jv.geom.PgElementSet, int, jv.vecmath.PdBaryDir, int, jv.vecmath.PiVector, jv.vecmath.PiVector)

calculateCurve

public void calculateCurve()

Calculates the integral curve with initial values internally given.

pickInitial

public void pickInitial(PvPickEvent pos)

Initiates calculation of an integral line that starts at picked position.

Overrides:

pickInitial in class PjProject

See Also:

calculateCurve()

setFast

public void setFast(boolean flag)

Sets integration method to euler-mode or 4th-order Runge-Kutta mode.

Parameters:

flag - true: euler; false: 4th-order runge-kutta

load

public boolean load(java.lang.String fileName)

Loads geometry via PjImportModel and then calls load().

Overrides:

load in class PjImportModel

See Also:

load()

load

public boolean load()

Gets geometry from PjImportModel and then triangulates, updates the number of elements, gets a vector field and fits that all in the display.

computeLIC

public void computeLIC()

run

public void run()

Gets an apropriate Runge-Kutta class and initiates LIC calculation element by element.

Specified by:

run in interface java.lang.Runnable
