Method Detail

getCoord3d

public Coordinate3d getCoord3d(double d1,
                               double d2,
                               double d3)

Description copied from class: GeneralProjector

Function ultimately used by a PamDataBlock to convert it's own data, in whatever form that is in into screen coordinates.

Specified by:

getCoord3d in class GeneralProjector

Parameters:

d1 - d2 and d3 are data representing whatever is appropriate for the concrete instance of the projector (e.g. Latitude, Longitude, depth, Time Frequency, etc)

Returns:

A 3 dimensional coordinate (realistically z is never currently used)

getAmplitudeCood3d

private Coordinate3d getAmplitudeCood3d(double bearing,
                                        double amplitude)

getRangeCood3d

private Coordinate3d getRangeCood3d(double bearing,
                                    double range)

be warned that this function will return null if the given bearing cannot be displayed !

Parameters:

bearing -

range -

Returns:

the 3-D coordinate of the given bearing and range

getPixelsPerMetre

public double getPixelsPerMetre()

setRadarParameters

public void setRadarParameters(RadarParameters radarParameters)

canPlot

private boolean canPlot(double bearing)

Return true if the point can be plotted on this particular display. This is based purely on the stye of the radar plot and whether or not the angle fits in within the drawn segment. Bearings are measured clockwise from north (geometric calculations are generally anti clockwise from east)

Returns:

true if the bearing can be plotted on the current display

getRadarDisplay

public RadarDisplay getRadarDisplay()
