Method Detail

setData

public void setData(double[][] data)

Description copied from interface: ElementPoints

Sets the data for the coordinates of the points. Each entry in the data array corresponds to one point.

Specified by:

setData in interface ElementPoints

Parameters:

data - double[][] the double[nPoints][3] array with the data

getData

public double[][] getData()

Description copied from interface: ElementPoints

Gets the data of the coordinates of the points

Specified by:

getData in interface ElementPoints

Returns:

double[][] the double[nPoints][3] array with the data

getExtrema

public void getExtrema(double[] min,
              double[] max)

Description copied from class: Element

Returns the extreme points of a box that contains the element.

Parameters:

min - double[] A previously allocated double[3] array that will hold the minimum point

max - double[] A previously allocated double[3] array that will hold the maximum point

getTargetHit

protected InteractionTarget getTargetHit(int x,
                             int y)

Description copied from class: Element

Gets the target that is under the (x,y) position of the screen

Overrides:

getTargetHit in class Element

Parameters:

x - int

y - int

Returns:

InteractionTarget

getLoader

public static XML.ObjectLoader getLoader()

Returns an XML.ObjectLoader to save and load object data.

Returns:

the XML.ObjectLoader
