public PwBoundary()

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

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)

Update workshop and 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.

See Also:

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

setGeometry

public void setGeometry(PgGeometry geom)

Assign a geometry, on which the workshop operates.

Specified by:

setGeometry in interface PjWorkshopIf

Overrides:

setGeometry in class PjWorkshop

Parameters:

geom - the workshop modifies this geometry.

removeBoundary

public void removeBoundary()

Remove boundary from the registered geometry.

makeBoundary

public void makeBoundary()

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. This is a non-static call for PjWorkshop use.

getCornerAngle

public double getCornerAngle()

Get maximal corner angle in [0,360] such that smaller vertex angles along the boundary are identified as sharp boundary vertices.

setCornerAngle

public void setCornerAngle(double angle)

Set maximal corner angle in [0,360] such that smaller vertex angles along the boundary are identified as sharp boundary vertices.

getLineTol

public double getLineTol()

Get tolerance allowed for points to vary from a line.

setLineTol

public void setLineTol(double lineTol)

Set tolerance allowed for points to vary from a line.

getPlaneTol

public double getPlaneTol()

Get tolerance allowed for points to vary from a plane.

setPlaneTol

public void setPlaneTol(double planeTol)

Set tolerance allowed for points to vary from a plane.

makeBoundary

public static void makeBoundary(PgElementSet elemSet)

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 information.

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 elemSet,
                                          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.
