Constructor

Method Detail

init

public void init()

Description copied from class: PjWorkshop

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjWorkshop

setGeometry

public void setGeometry(PgGeometry geom)

Assign a geometry on which this workshop operates, and create a backup copy if workshop is cancelled. Subclasses frequently overwrite this method but are advised to call this method.

Specified by:

setGeometry in interface PjWorkshopIf

Overrides:

setGeometry in class PjWorkshop

Parameters:

geom - the workshop modifies this geometry.

getFunction

public java.lang.String getFunction()

Get textual expression of level function.

setFunction

public void setFunction(java.lang.String s)

Set textual expression of level function used clipping from outside of workshop. String must be a valid mathematical function in variables {u,v,w} where the number of variables must be equal to the vertex dimension of the geometry to which clipping is applied.

Parameters:

s - string containing a function expression

Parser

getLevel

public double getLevel()

Get level value at which clipping happens.

Returns:

Level value at which clipping happens.

setLevel

public void setLevel(double level)

Set the value at which clipping happens.

Parameters:

level - Level value at which clipping happens.

setEnabledPositive

public void setEnabledPositive(boolean showPositive)

Set comparison sign for function level.

isEnabledPositive

public boolean isEnabledPositive()

Get comparison sign for function level.

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.

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

clipAtFunction

public void clipAtFunction()

Cut all elements of the workshop's geometry at the level value.
