Deprecated. use constructor prj=new PwModel();prj.setGeometry(geom);prj.reset();

Method Summary

boolean	compute() Update the registered geometry based on the currently selected solid type.
static void	dual(PgElementSet geom) Get the dual PgElementSet: Each vertex will be replaced by an element, having the center points of the adjacent elements as vertices; new boundary elements get two additional vertices at the boundary edge midpoints, if the vertex had only one adjacent element, the new element will contain also the old vertex.
static void	extrude(PgElementSet geom, double factor) Reduplicate geometry with vertices at the tips of the vertex normals and fill the gaps at the boundaries with quadrilaterals.
int	getModelingType() Get the current modeling type.
void	init() Initialisation.
boolean	isEnabledModeling() Return flag whether to apply current modeling mode to the workshop's geometry.
static void	punch(PgElementSet geom, double factor) Cut out a shrinked copy from every element; the remaining face gets divided into quadrilaterals, each containing one edge of the original element and of the cut-out shrinked copy.
void	reset() Reset workshop and geometry to original state.
void	setElementSet(PgElementSet geom) Deprecated. use setGeometry(PgElementSet).
void	setEnabledModeling(boolean flag) Define flag whether to apply current modeling mode to the workshop's geometry.
void	setGeometry(PgElementSet geom) Overwrite the backup element set, on which the modeling tools will work.
void	setModelingType(int type) Set the current modeling type.
static void	shrink(PgElementSet geom, double factor) Shrink every face of ElementSet by a constant factor; every face gets it's own edges and vertices, all neighbourhood information gets lost.
static void	stellate(PgElementSet geom, double h) Replace every face by a pyramide dimension of Elements gets set to 3.
static void	truncate(PgElementSet geom, double factor, boolean newFaces) Truncate all vertices.
boolean	update(java.lang.Object event) Update the class whenever a child has changed.

Method Detail

init

public void init()

Initialisation.

Overrides:

init in class PjWorkshop

reset

public void reset()

Reset workshop and geometry to original state.

Overrides:

reset in class PjWorkshop

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.

compute

public boolean compute()

Update the registered geometry based on the currently selected solid type.

See Also:

setGeometry(PgElementSet), setModelingType(int)

setGeometry

public void setGeometry(PgElementSet geom)

Overwrite the backup element set, on which the modeling tools will work.

setElementSet

public void setElementSet(PgElementSet geom)

Deprecated. use setGeometry(PgElementSet).

Overwrite the backup elementSet, on which the modeling tools will work.

getModelingType

public int getModelingType()

Get the current modeling type.

setModelingType

public void setModelingType(int type)

Set the current modeling type. At the same time the parameter bounds of the previous modeling type are saved to the max/min values.

setEnabledModeling

public void setEnabledModeling(boolean flag)

Define flag whether to apply current modeling mode to the workshop's geometry.

isEnabledModeling

public boolean isEnabledModeling()

Return flag whether to apply current modeling mode to the workshop's geometry.

shrink

public static void shrink(PgElementSet geom,
                          double factor)

Shrink every face of ElementSet by a constant factor; every face gets it's own edges and vertices, all neighbourhood information gets lost.

Parameters:

factor - shrinking factor

stellate

public static void stellate(PgElementSet geom,
                            double h)

Replace every face by a pyramide dimension of Elements gets set to 3.

Parameters:

h - height of pyramide

truncate

public static void truncate(PgElementSet geom,
                            double factor,
                            boolean newFaces)

Truncate all vertices.

Parameters:

geom - Geometry to operate on.

factor - blend factor for Vertices

newFaces - true = replace truncated vertices with new faces

punch

public static void punch(PgElementSet geom,
                         double factor)

Cut out a shrinked copy from every element; the remaining face gets divided into quadrilaterals, each containing one edge of the original element and of the cut-out shrinked copy.

Parameters:

factor - shrinking factor for the cut-out element.

dual

public static void dual(PgElementSet geom)

Get the dual PgElementSet: Each vertex will be replaced by an element, having the center points of the adjacent elements as vertices; new boundary elements get two additional vertices at the boundary edge midpoints, if the vertex had only one adjacent element, the new element will contain also the old vertex. Each element will be replaced by a vertex at its center.

Create new boundary only when original geometry has boundary.

extrude

public static void extrude(PgElementSet geom,
                           double factor)

Reduplicate geometry with vertices at the tips of the vertex normals and fill the gaps at the boundaries with quadrilaterals.

Parameters:

factor - Factor to multiply vertex normals with.
