Method Detail

from

public static PolygonBound from(float[] abscissa,
                                float[] ordinate,
                                int limit)

abscissa and ordinate contain the coordinates of polygon. abscissa[i] is the horizontal coordinate for the i'th corner of the polygon, and ordinate[i] is the vertical coordinate for the i'th corner. The polygon must have more than 2 corners, so the length of abscissa or ordinate must be equal or greater than 3. if the polygon is a rectangular, which corners are {0.0, 0.0}, {0.0, 1.0}, {1.0, 1.0}, {1.0, 0.0}, the abscissa should be {0.0, 0.0, 1.0, 1.0} and ordinate should be {0.0, 1.0, 1.0, 0.0}
