Constructor Detail

PickManipulationRendererJ3D

public PickManipulationRendererJ3D()

Default constructor

PickManipulationRendererJ3D

public PickManipulationRendererJ3D(int mmm,
                                   int mmv)

Construct a new PickManipulationRenderer using the mouseModifiers supplied. 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 mask.

mmv - mouse modifiers value.

Method Detail

checkDirect

public void checkDirect()
                 throws VisADException,
                        RemoteException

Check if direct manipulation is possible.

Overrides:

checkDirect in class DirectManipulationRendererJ3D

Throws:

VisADException - a VisAD error occurred

RemoteException - an RMI error occurred

getWhyNotDirect

public String getWhyNotDirect()

If direct manipulation is not possible, get the error message explaining why.

Overrides:

getWhyNotDirect in class DataRenderer

Returns:

error message. Will be null if no errors.

addPoint

public void addPoint(float[] x)
              throws VisADException

Add a point. a no-op at this point.

Overrides:

addPoint in class DirectManipulationRendererJ3D

Parameters:

x - point value.

Throws:

VisADException - a VisAD error occurred

getDisplayCoordinateSystem

public CoordinateSystem getDisplayCoordinateSystem()

Get the CoordinateSystem for the display side.

Overrides:

getDisplayCoordinateSystem in class DataRenderer

Returns:

null for this DataRenderer

setSpatialValues

public void setSpatialValues(float[][] spatial_values)

Set spatialValues from ShadowType.doTransform

Overrides:

setSpatialValues in class DataRenderer

Parameters:

spatial_values - X, Y, Z values

checkClose

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

Check if ray intersects sub-manifold.

Overrides:

checkClose in class DataRenderer

Parameters:

origin - x,y,z values of the ray

direction - x,y,z values of the ray?

Returns:

distance from the spatial values.

getCloseIndex

public int getCloseIndex()

Return the index of the closes point.

Returns:

index of closest point

drag_direct

public void drag_direct(VisADRay ray,
                        boolean first,
                        int mouseModifiers)

Actual workhorse method of manipulation renderer. It's what gets called when the click is done.

Overrides:

drag_direct in class DataRenderer

Parameters:

ray - ray of point where click is.

first - if this is the first time.

mouseModifiers - modifiers used with the mouse.

clone

public Object clone()

Overrides:

clone in class DirectManipulationRendererJ3D

Returns:

a copy of this DataRenderer

main

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

test PickManipulationRendererJ3D

Throws:

VisADException

RemoteException
