Constructor Detail

ColorSurfaceData

public ColorSurfaceData(int nX,
                        int nY)

The data set constructor with size of the grid.

Method Detail

setColorGenerator

public void setColorGenerator(ColorGenerator colorGen)

Sets the color generator.

getColorGenerator

public ColorGenerator getColorGenerator()

Returns the color generator instance.

setSize

public void setSize(int nX,
                    int nY)

Sets data size. It will clean the data inside.

setScreenResolution

public void setScreenResolution(int nScreenX,
                                int nScreenY)

Sets the screen resolution.

getScreenSizeX

public int getScreenSizeX()

Returns the horizontal screen resolution.

getScreenSizeY

public int getScreenSizeY()

Returns the vertical screen resolution.

getSizeX

public int getSizeX()

Returns the X size of the 2D array.

getSizeY

public int getSizeY()

Returns the Y size of the 2D array.

getX

public double getX(int i)

Returns the X value of the grid for the index i.

getY

public double getY(int j)

Returns the Y value of the grid for the index j.

getMinX

public double getMinX()

Returns the minimal X value of the grid.

getMaxX

public double getMaxX()

Returns the maximal X value of the grid.

getMinY

public double getMinY()

Returns the minimal Y value of the grid.

getMaxY

public double getMaxY()

Returns the maximal Y value of the grid.

getMinZ

public double getMinZ()

Returns the minimal Z value.

getMaxZ

public double getMaxZ()

Returns the maximal Z value.

setMinMaxX

public void setMinMaxX(double x_min,
                       double x_max)

Sets the minimal maximal X value of the grid.

setMinMaxY

public void setMinMaxY(double y_min,
                       double y_max)

Sets the minimal maximal Y value of the grid.

setZero

public void setZero()

Sets all values of the 2D array to 0.

setValue

public void setValue(int i,
                     int j,
                     double value)

Returns the value of the 2D array with indexes i and j.

getValue

public abstract double getValue(double x,
                                double y)

Returns the interpolated value of the 2D array for x and y. The subclasses should implement this method to provide specific interpolation scheme.

addValue

public abstract void addValue(double x,
                              double y,
                              double value)

Bins value into the 2D array for x and y with weight = value. The subclasses should implement this method to provide specific interpolation scheme.

addValue

public void addValue(double x,
                     double y)

Bins value into the 2D array for x and y with weight = 1.

multiplyBy

public void multiplyBy(double value)

Multiplies all values of the 2D array by constant factor = value.

calcMaxMinZ

public void calcMaxMinZ()

Calculates minimal and maximal Z values. In the begining all data = 0., and if you want to get real min and max for Z you should use this method first.

getColor

public java.awt.Color getColor(double x,
                               double y)

Returns the color for (x,y) point.
