PgSurface_KleinBottle

public PgSurface_KleinBottle()

Method Detail

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.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PgSurfaceDescr

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

See Also:

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

isUPeriodic

public boolean isUPeriodic()

Description copied from class: PgSurfaceDescr

Determine if surface is periodic in u-direction. This method returns false, but will be overwritten by surface which are periodic.

Overrides:

isUPeriodic in class PgSurfaceDescr

isVPeriodic

public boolean isVPeriodic()

Description copied from class: PgSurfaceDescr

Determine if surface is periodic in v-direction. This method returns false, but will be overwritten by surface which are periodic.

Overrides:

isVPeriodic in class PgSurfaceDescr

calc_f

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

Description copied from class: PgSurfaceDescr

Internal function called by eval(..) to compute function value. It is ensured by the calling eval() function that argument vector exists and has correct size.

If function set flag m_bUseFunctionExpression==false then we use this indicator that function has not been overridden and use the string functions.

This function must be overwritten by subclasses to compute surfaces, for example, if a subclass wants to perform the function calculation itself.

Overrides:

calc_f in class PgSurfaceDescr

Parameters:

fun - vector where to place the function values.

Returns:

true if function has been overridden and evaluated successfully.
