Class Plot3DState

java.lang.Object

uk.ac.starlink.ttools.plot.PlotState

uk.ac.starlink.ttools.plot.Plot3DState

Direct Known Subclasses:

SphericalPlotState

public class Plot3DState
extends PlotState

PlotState subclass which has specific features for specifying the state of 3D scatter plots. The most important extra feature is the rotation matrix, which describes the viewing angle for the 3D data space.

Constructor Detail

Plot3DState

public Plot3DState()

Method Detail

setRotation

public void setRotation(double[] matrix)

Sets the rotation matrix.

Parameters:

matrix - 9-element 3d rotation matrix

getRotation

public double[] getRotation()

Returns the rotation matrix.

Returns:

9-element 3d rotation matrix

setFogginess

public void setFogginess(double fog)

Sets the intensity of fog used for depth rendering (1 is a reasonable amount; 0 is no fog).

Parameters:

fog - fog intensity

getFogginess

public double getFogginess()

Returns the intensity of fog used for depth rendering.

Returns:

fog intensity

setRotating

public void setRotating(boolean isRotating)

Sets whether the plot is currently rotating. A true value for this indicates that the whole set of data points does not need to be drawn; a sequence of plot requests with isRotating true must be followed quickly by one with isRotating false.

Parameters:

isRotating - true iff this plot is currently in the middle of a sequence of rotation operations

getRotating

public boolean getRotating()

Indicates whether the plot is currently rotating. A true value for indicates that the whole set of data points does not need to be drawn; a sequence of plot requests with isRotating true must be followed quickly by one with isRotating false.

Returns:

true if not all the points need to be drawn this time

setZoomScale

public void setZoomScale(double zoomScale)

Returns the zoom level. Unity is normal size, and a larger number means more magnification.

Parameters:

zoomScale - zoom level

getZoomScale

public double getZoomScale()

Sets the zoom level.

Returns:

zoom level

equals

public boolean equals(Object otherObject)

Overrides:

equals in class PlotState

hashCode

public int hashCode()

Overrides:

hashCode in class PlotState
