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

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 should be overwritten by subclasses to compute surfaces.

HACK: Access lowered to public since other javadoc comments refer to class.

Overrides:

calc_f in class PgSurfaceDescr

Following copied from class: vgp.surface.common.PgSurfaceDescr

Parameters:

f - vector where to place the function values.

Returns:

true if function has been overridden and evaluated successfully.
