Method Detail

setClosed

void setClosed(boolean closed)

Sets whether the polygon is closed

Parameters:

closed - boolean

isClosed

boolean isClosed()

Gets whether the polygon is closed

Returns:

boolean

setData

void setData(double[][] data)

Sets the data for the points of the polygon. Each entry in the data array corresponds to one vertex. If the polygon is closed, the last point will be connected to the first one and the interior will be filled (unless the fill color of the style is set to null).

Parameters:

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

setData

void setData(double[] xArray,
             double[] yArray,
             double[] zArray)

Sets the data for the points of the polygon. Each entry in the data array corresponds to one vertex. If the polygon is closed, the last point will be connected to the first one and the interior will be filled (unless the fill color of the style is set to null). The data array is copied, so subsequence changes to the original array do not affect the polygon, until the setData() method is invoked. If the arrays have different lengths, the last element of the shortest array is repeated to match the longest array.

Parameters:

xArray - double[] the double[nPoints] array with the X coordinates

yArray - double[] the double[nPoints] array with the Y coordinates

zArray - double[] the double[nPoints] array with the Z coordinates

getData

double[][] getData()

Gets ths data of the points fo the polygon

Returns:

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