Constructor Detail

CurveManipulationRendererJ3D

public CurveManipulationRendererJ3D()

Construct a DataRenderer that supports direct manipulation of representations of curves by UnionSets of Gridded2DSets with manifold dimension = 2; the Set's domain RealTypes must be mapped to two of (XAxis, YAxis, ZAxis).

CurveManipulationRendererJ3D

public CurveManipulationRendererJ3D(int mmm,
                                    int mmv)

Construct a DataRenderer that supports direct manipulation of representations of curves by UnionSets of Gridded2DSets with manifold dimension = 2; the Set's domain RealTypes must be mapped to two of (XAxis, YAxis, ZAxis). mmm and mmv determine whehter SHIFT or CTRL keys are required - this is needed since this is a greedy DirectManipulationRenderer that will grab any right mouse click (that intersects its 2-D sub-manifold)

Parameters:

mmm - mouse modifiers

mmv - mouse mask to check.

CurveManipulationRendererJ3D

public CurveManipulationRendererJ3D(int mmm,
                                    int mmv,
                                    boolean oo)

Construct a DataRenderer that supports direct manipulation of representations of curves by UnionSets of Gridded2DSets with manifold dimension = 2; the Set's domain RealTypes must be mapped to two of (XAxis, YAxis, ZAxis). mmm and mmv determine whehter SHIFT or CTRL keys are required - this is needed since this is a greedy DirectManipulationRenderer that will grab any right mouse click (that intersects its 2-D sub-manifold)

Parameters:

mmm - mouse modifiers

mmv - mouse mask to check.

oo - if true, only one curve should exist at any one time.

Method Detail

makeShadowSetType

public ShadowType makeShadowSetType(SetType type,
                                    DataDisplayLink link,
                                    ShadowType parent)
                             throws VisADException,
                                    RemoteException

Create a ShadowType based on the SetType

Overrides:

makeShadowSetType in class RendererJ3D

Parameters:

type - SetType of UnionSet.

link - DataDisplayLink for DataReference

parent - Parent ShadowType

Returns:

constructed ShadowType

Throws:

VisADException - problem creating a VisAD object

RemoteException - problem creating a remote object

checkDirect

public void checkDirect()
                 throws VisADException,
                        RemoteException

Check whether direct manipulation is possible for this Renderer. Set appropriate error conditions if not possible.

Overrides:

checkDirect in class DirectManipulationRendererJ3D

Throws:

VisADException - problem accessing information

RemoteException - problem accessing information for remote objects

getWhyNotDirect

public String getWhyNotDirect()

Get the error messages on why direct manipulation is not possible.

Overrides:

getWhyNotDirect in class DataRenderer

Returns:

error messages.

addPoint

public void addPoint(float[] x)
              throws VisADException

Add a point to the data. Not used, but may be needed for performance.

Overrides:

addPoint in class DirectManipulationRendererJ3D

Parameters:

x - point to add.

Throws:

VisADException - error occured.

setSpatialValues

public void setSpatialValues(float[][] spatial_values)

Set spatialValues from ShadowType.doTransform.

Overrides:

setSpatialValues in class DataRenderer

Parameters:

spatial_values - spatial values.

checkClose

public float checkClose(double[] origin,
                        double[] direction)

Find minimum distance from ray to spatialValues.

Overrides:

checkClose in class DataRenderer

origin - origin of ray

direction - direction of the ray

Returns:

miniumum distance from ray to spatial values

setGreedy

Overrides:

release_direct in class DataRenderer

stop_direct

public void stop_direct()

Stop direct manipulation.

Overrides:

stop_direct in class DataRenderer

This method is called when direct manipulation is occuring. This adds points to the Gridded2DSet that comprises the current line being drawn.

Overrides:

drag_direct in class DataRenderer

Parameters:

ray - ray to dragging point of mouse

first - true if this is the first point.

mouseModifiers - modifiers used with mouse click.

clone

public Object clone()

Clone this renderer.

Overrides:

clone in class DirectManipulationRendererJ3D

Returns:

new Renderer with same parameters.

main

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