Constructor

Method Detail

init

public void init()

Initialization

Overrides:

init in class PjWorkshop

reset

public void reset()

Reset workshop and geometry to original state.

Overrides:

reset in class PjWorkshop

update

public boolean update(java.lang.Object event)

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

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.

See Also:

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

setGeometry

public void setGeometry(PgPointSet geom)

Assign geometry on which this workshop operates.

close

public void close()

Close this workshop, and here, stop and remove any animation.

Overrides:

close in class PjWorkshop

isEnabledFlip

public boolean isEnabledFlip()

Check if direction of flow is flip against direction of vector field.

Since:

JavaView 2.60.001

Version:

11.03.03, 1.00 created (kp)

setEnabledFlip

public void setEnabledFlip(boolean flag)

Set if direction of flow is flip against direction of vector field.

Since:

JavaView 2.60.001

Version:

11.03.03, 1.00 created (kp)

isEnabledUpdateNormals

public boolean isEnabledUpdateNormals()

Check if update of normal vectors after each timestep is enabled.

Since:

JavaView 2.66.001

Version:

30.03.03, 1.00 created (kp)

setEnabledUpdateNormals

public void setEnabledUpdateNormals(boolean flag)

Enable update of normal vectors after each timestep.

Since:

JavaView 2.66.001

Version:

30.03.03, 1.00 created (kp)

getDirection

public int getDirection()

Get direction currently used for evolution. Possible values are PnEvolve#OFFSET_VERTEX_NORMAL, PnEvolve#OFFSET_VERTEX_VECTOR and others, see PnEvolve. and others.

setDirection

public int setDirection(int dir)

Set direction currently used for evolution. Possible values are PnEvolve#OFFSET_VERTEX_NORMAL, PnEvolve#OFFSET_VERTEX_VECTOR and others, see PnEvolve. and others.

getOffsetFactor

public double getOffsetFactor()

Get evolution distance. The evolution distance is equal to offsetFactor*vector.

setOffsetFactor

public void setOffsetFactor(double offsetFactor)

Set evolution distance. The evolution distance is equal to offsetFactor*vector.

compute

public void compute()

Evolve geometry in direction of the currently active evolution type. The evolution distance is equal to offsetFactor*vector.

setTime

public boolean setTime(PsTimeEvent time)

Compute evolution.

Specified by:

setTime in interface PsTimeListenerIf

start

public void start()

Create a new animation and start it.

Version:

11.08.14, 1.10 revised (kp) Repeat set to one-way.

stop

public void stop()

Stop the animation.

getAnimation

public PsAnimation getAnimation()

Get the animation object of the project which handles the projects animations. This listener may only have a single animation object which is assigned by the animation object when this listener is registered using setAnimation(PsAnimation).

Specified by:

getAnimation in interface PsTimeListenerIf

See Also:

hasAnimation(), setAnimation(PsAnimation)

hasAnimation

public boolean hasAnimation()

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

Specified by:

hasAnimation in interface PsTimeListenerIf

See Also:

getAnimation(), setAnimation(PsAnimation)

setAnimation

public void setAnimation(PsAnimation anAnimation)

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

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

Specified by:

setAnimation in interface PsTimeListenerIf
