Method Details

zero

public void zero()

Sets the value of all vertexes to be zero

area

public double area()

Returns the area of this quadrilateral

Returns:

area

get

public Point2D_F64 get(int index)

getLine

public LineSegment2D_F64 getLine(int which,
 LineSegment2D_F64 storage)

getSideLength

public double getSideLength(int which)

getSideLength2

public double getSideLength2(int which)

setTo

public void setTo(Quadrilateral_F64 quad)

convert

public List<Point2D_F64> convert(@Nullable
 @Nullable List<Point2D_F64> storage,
 boolean copy)

Converts the polygon into a list.

Parameters:

storage - (Optional) storage to put the vertexes into

copy - If points will be copied otherwise a reference of points will be returned

Returns:

List of vertexes

setTo

public void setTo(List<Point2D_F64> list)

Sets the polygon to be the same as the list. A true copy is created and no references to points in the list are saved.

Parameters:

list - List which the polygon will be set to

copy

public Quadrilateral_F64 copy()

isEquals

public boolean isEquals(Quadrilateral_F64 quad,
 double tol)

Returns true if the two quadrilaterals are equal to each other to within tolerance. Equality is defined by seeing if the distance between two equivalent vertexes is within tolerance.

Parameters:

quad - The second quadrilateral

tol - Maximum allowed distance between vertexes.

Returns:

true if equals or false if not

toString

public String toString()

Overrides:

toString in class Object
