Method Details

getImplementations

public static Map<String,ConvexHullTest.ConvexHullImplementation> getImplementations()

Create the map of all convex hull implementations.

Returns:

Map<String, ConvexHullImplementation>; the map of all convex hull implementations

testConvexHull

@Test
public void testConvexHull()

Test a convex hull implementation.

main

public static void main(String[] args)
                 throws IOException

Compare performance.

Parameters:

args - String[]; the command line arguments (not used)

Throws:

IOException - ...

checkImplementations

public static void checkImplementations(Map<String,ConvexHullTest.ConvexHullImplementation> implementations,
 List<Point2d> in,
 Polygon2d expectedResult)

Check that all implementations of convex hull give the expected result.

Parameters:

implementations - Map<String, ConvexHullImplementation>; the implementations to check

in - List<Point2d>; the input for the convex hull implementations

expectedResult - Polygon2d; the expected result
