Constructor Detail

ProjectionControlJ3D

public ProjectionControlJ3D(DisplayImpl d)
                     throws VisADException

Construct a new ProjectionControl for the display. The initial projection is saved so it can be reset with resetProjection().

Parameters:

d - display whose projection will be controlled by this

Throws:

VisADException

See Also:

ProjectionControl.resetProjection().

Method Detail

setMatrix

public void setMatrix(double[] m)
               throws VisADException,
                      RemoteException

Set the projection matrix.

Overrides:

setMatrix in class ProjectionControl

Parameters:

m - new projection matrix

Throws:

VisADException - VisAD error

RemoteException - remote error

setAspect

public void setAspect(double[] aspect)
               throws VisADException,
                      RemoteException

Set the aspect for the axes. Default upon initialization is 1.0, 1.0, 1.0. Invokes saveProjection to set this as the new default.

Specified by:

setAspect in class ProjectionControl

Parameters:

aspect - ratios (dimension 3) for the X, Y, and Z axes

Throws:

VisADException - aspect is null or wrong dimension or other error

RemoteException - remote error

See Also:

ProjectionControl.saveProjection()

addPair

public void addPair(Switch sw,
                    DataRenderer re)

clearSwitches

public void clearSwitches(DataRenderer re)

clear all 'pairs' in switches that involve re

Overrides:

clearSwitches in class ProjectionControl

setOrthoView

public void setOrthoView(int view)
                  throws VisADException,
                         RemoteException

Set the projection so the requested view is displayed.

Parameters:

view - one of the static view fields (X_PLUS, X_MINUS, etc). This will set the view so the selected face is orthogonal to the display.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.
