Method Detail

init

public void init()

Description copied from class: PsObject

If instance has missing name then assign default name 'object_NUMBER' where number is the total number of already created instances.

Overrides:

init in class PsObject

setGeometry

public void setGeometry(PgElementSet geom)

Sets the triangulation.

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 class: jv.object.PsObject

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

setFast

public void setFast(boolean flag)

Sets whether 4th-order runge-kutta or euler integration will be used.

Parameters:

flag - true: euler; false: 4th order r.-k.

isComputingLIC

public boolean isComputingLIC()

Returns:

true if the LIC thread is running at the moment

startLIC

public void startLIC()

Starts a new thread that computes the LIC texture.
