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

reset

public void reset()

Reset this workshop to its initial state from which computations can start.

Overrides:

reset in class PjWorkshop

close

public void close()

Close workshop and remove itself as listener from various classes. The workshop will no longer be functional after this call.

Overrides:

close in class PjWorkshop

ok

public void ok()

Accept the current state of the geometry and close the workshop.

Overrides:

ok in class PjWorkshop

update

public boolean update(java.lang.Object event)

Description copied from class: PjWorkshop

Updates the geometry if this workshop has changed, i.e. if the event is this or null. Also propagates update() to superclass with the original argument event.

Some subclasses may register themself as update listener of the geometry of this workshop. In order to prevent an update loop, this method savely uses isUpdateSender() when updating the geometry.

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.

makeBoundary

public static void makeBoundary(PgElementSet elementSet)

Generate boundary polygons for a PgElementSet. Boundary polygons will start and end preferentially at vertices with tag PsObject.IS_SELECTED. This method requires correct neighbourhood informations.

isEnabledMakeConstraints

public boolean isEnabledMakeConstraints()

Check if boundary constraints will be generate when boundary is created.

Returns:

true if making of boundary constraints is enabled.

setEnabledMakeConstraints

public void setEnabledMakeConstraints(boolean flag)

Set flag which determines if boundary constraints will be generate when boundary is created.

Parameters:

flag - true to enable making of boundary constraints.

makeBoundaryConstraints

public void makeBoundaryConstraints()

Make boundary constraints for existing PgBndPolygons. Polygons get constrained to a straight line, if they contain at least three vertices and all vertices lie upon this straight line. Polygons get constrained to a plane or a circle, if they contain at least four vertices and all vertices lie upon the plane or circle. This is a non-static call for PjWorkshop use.

makeBoundaryConstraint

public static void makeBoundaryConstraint(PgElementSet geom,
                                          int bndIndex,
                                          double lineTol,
                                          double planeTol)

Make boundary constraints for an existing PgBndPolygon. The polygon gets constrained to a straight line, if it contains at least three vertices and all vertices lie upon this straight line. The polygon gets constrained to a plane or a circle, if it contains at least four vertices and all vertices lie upon the plane or circle.
