Constructor Details

IsoSurface

public IsoSurface(String name,
 RealType contourRealType,
 boolean alphaflag)
           throws VisADException,
RemoteException

Constructs from a name for the Displayable and the type of the iso-surface parameter.

Parameters:

name - The name for the displayable.

contourRealType - The type of the iso-surface parameter. May be null.

alphaflag - boolean flag whether to use transparency

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

IsoSurface

protected IsoSurface(IsoSurface that)
              throws VisADException,
RemoteException

Constructs from another instance. The following attributes are set from the other instance: surface value, the contour RealType.

Parameters:

that - The other instance.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

Method Details

setContourRealType

protected void setContourRealType(RealType realType)
                           throws RemoteException,
VisADException

Sets the RealType of the contoured parameter.

Parameters:

realType - The RealType of the contoured parameter. May not be null.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

setDisplayUnit

public void setDisplayUnit(Unit unit)
                    throws VisADException,
RemoteException

Set the units for the displayed range

Overrides:

setDisplayUnit in class RGBDisplayable

Parameters:

unit - Unit for display

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

getContourRealType

public RealType getContourRealType()

Returns the RealType of the contoured parameter.

Returns:

The RealType of the contoured parameter. May be null.

setSurfaceValue

public final void setSurfaceValue(float value)
                           throws RemoteException,
VisADException

Sets the "contour" value, the value of the isosurface. This method fires a PropertyChangeEvent for SURFACE_VALUE.

Parameters:

value - The value of the isosurface.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

See Also:

• SURFACE_VALUE

setScalarMaps

protected void setScalarMaps(ScalarMapSet maps)
                      throws BadMappingException

Sets the set of ScalarMap-s of this instance. The ScalarMap-s of this instance will be added to the set before the SCALAR_MAP_SET property is set. This method fires a PropertyChangeEvent for SCALAR_MAP_SET with null for the old value and the new set of ScalarMap-s for the new Value. Intermediate subclasses that have their own ScalarMap-s should override this method and invoke super.setScalarMaps(ScalarMapSet).

Overrides:

setScalarMaps in class RGBDisplayable

Parameters:

maps - The set of ScalarMap-s to be added.

Throws:

BadMappingException - The RealType of the contour parameter has not been set or its ScalarMap is alread in the set.

getSurfaceValue

public final float getSurfaceValue()

Gets the value of the isosurface

Returns:

float value of the isosurface
