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 workshop and geometry to original state.

Overrides:

reset in class PjWorkshop

update

public boolean update(java.lang.Object event)

Each time another geometry is loaded.

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.

setGeometry

public void setGeometry(PgGeometry geom)

Description copied from class: PjWorkshop

Assign a geometry on which this workshop operates, and create a backup clone of the geometry. The backup geometry is restored if the workshop is cancelled.

Subclasses frequently overwrite this method but are adviced to call this method.

Specified by:

setGeometry in interface PjWorkshopIf

Overrides:

setGeometry in class PjWorkshop

Parameters:

geom - the workshop modifies this geometry.

cancel

public void cancel()

Cancel operation of this workshop by resetting the assigned geometry, and finally close this workshop.

If necessary, the duplicate of the original geometry is restored into the geometry.

Overrides:

cancel in class PjWorkshop

getLevels

public PdVector getLevels()

setLevels

public void setLevels(PdVector level)

getRangeType

public int getRangeType()

setRangeType

public void setRangeType(int type)

makeIsolines

public void makeIsolines()

Compute isolines of selected scalar field of geometry.

makeIsolines

public static PgPolygonSet makeIsolines(PgElementSet geom,
                                        PdVector levels,
                                        PgPolygonSet isolines,
                                        PdVector scalar)

Computes a set of isolines of a scalar field on a triangulated surface. The function is given as a PdVector. Each double of the vector is regarded as the function value of the vertex of the surface with the corresponding index. In the interior of elements the function is linearly interpolated. The isolines are returned as a list of polygons each consisting of only one edge. The isovalue of each polygon is given as a PdVector. To simplify the polygon set see PuCleanMesh.identifyVertices(PgGeometry) and PwCleanMesh.joinPolygons.

Parameters:

geom - Base surface must consist of triangles only.

levels - List of values sorted by increasing value, determines the computed isolines.

isolines - Isocurves which will be computed.

scalar - Scalar values at each vertex of the base geometry.
