public class PgSurface_CatenoidHelicoid

extends PgSurfaceDescr

implements PsTimeListenerIf

Parametrized surface given by method, or interactively, by function expressions. If the functions of a surface are specified in calc_f method and, later, interactively edited, then the interactive expressions are further used. This is important for evaluation of higher order differentials since they are only approximated using finite differences in the later case.

public PgSurface_CatenoidHelicoid()

Method Detail

isUPeriodic

public boolean isUPeriodic()

Overrides:

isUPeriodic in class PgSurfaceDescr

init

public void init()

Description copied from class: PgDomainDescr

Initialize and reset data structure and all instance variables.

Overrides:

init in class PgSurfaceDescr

update

public boolean update(java.lang.Object event)

Description copied from class: PgSurfaceDescr

Catch events from function strings. Update the class whenever a child has changed. Method is usually invoked from the children.

Overrides:

update in class PgSurfaceDescr

Following copied from class: jv.object.PsObject

calc_f

public boolean calc_f(PdVector fun,
                      double u,
                      double v)

setTime

public boolean setTime(PsTimeEvent timeEvent)

Description copied from interface: PsTimeListenerIf

Animation updates the dynamic object through this method whenever time has changed.

Specified by:

setTime in interface PsTimeListenerIf

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.

If this project has an animation object assigned in its constructor or init() method, then the animation panel is shown when the project's start() method is invoked during loading of the project.

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

Specified by:

setAnimation in interface PsTimeListenerIf

getAnimation(), hasAnimation()
