Method Detail

setResolutions

public void setResolutions(int[] rs)
                    throws RemoteException

Throws:

RemoteException

prepareAction

public DataShadow prepareAction(boolean go,
                                boolean initialize,
                                DataShadow shadow)
                         throws VisADException,
                                RemoteException

Description copied from class: DataRenderer

check if re-transform is needed; if initialize is true then compute ranges for RealTypes and Animation sampling

Overrides:

prepareAction in class DataRenderer

Parameters:

go - flag indicating that re-transform is required for at least one DataRenderer linked to DisplayImpl

initialize - flag indicating that initialization (i.e., auto-scaling) is required

shadow - DataShadow shared by prepareAction() method of all DataRenderers linked to DisplayImpl

Returns:

DataShadow containing ranges and animation sampling Set (return null if no need for initialization)

Throws:

VisADException - a VisAD error occurred

RemoteException - an RMI error occurred

doTransform

public BranchGroup doTransform()
                        throws VisADException,
                               RemoteException

create a scene graph for Data in links[0]

Overrides:

doTransform in class DefaultRendererJ3D

Throws:

VisADException

RemoteException

setSpatialValues

public void setSpatialValues(float[][] spatial_values)

Description copied from class: DataRenderer

set spatial values for Data depiction; used to detect when direct manipulation mouse selects a point of a Data depiction

Overrides:

setSpatialValues in class DataRenderer

Parameters:

spatial_values - float[3][number_of_points] of 3-D locations of depiction points

convertSceneGraph

public Node convertSceneGraph(VisADSceneGraphObject scene)
                       throws VisADException

Throws:

VisADException

computeRanges

public DataShadow computeRanges(Data data,
                                ShadowType type,
                                DataShadow shadow)
                         throws VisADException,
                                RemoteException

Description copied from class: DataRenderer

Compute ranges of values for each RealType in DisplayImpl.RealTypeVector.

Overrides:

computeRanges in class DataRenderer

Parameters:

data - Data object in which to compute ranges of RealType values

type - ShadowType generated for MathType of data

shadow - DataShadow instance whose contained double[][] array and animation sampling Set are modified according to RealType values in data, and used as return value

Returns:

DataShadow instance containing double[][] array of RealType ranges, and an animation sampling Set

Throws:

VisADException - a VisAD error occurred

RemoteException - an RMI error occurred

clone

public Object clone()

Overrides:

clone in class DefaultRendererJ3D

Returns:

a copy of this DataRenderer

main

public static void main(String[] args)
                 throws VisADException,
