Method Details

bezierTest2d

@Test
public final void bezierTest2d()
                        throws DrawRuntimeException,
DrawRuntimeException

Test the various 2d methods in the Bezier class.

Throws:

DrawRuntimeException - when this happens uncaught this test has failed

DrawRuntimeException - when this happens uncaught; this test has failed

compareBeziers

public void compareBeziers(String description,
 PolyLine2d reference,
 PolyLine2d candidate,
 int numberOfPoints,
 double epsilon)
                    throws DrawRuntimeException

Compare Bézier curve approximations.

Parameters:

description - String; description of the test

reference - PolyLine2d; reference Bézier curve approximation

candidate - PolyLine2d; candidate Bézier curve approximation

numberOfPoints - int; number of point to compare the curves at, minus one; this method checks at 0% and at 100%

epsilon - double; upper limit of the distance between the two curves

Throws:

DrawRuntimeException - if that happens uncaught; a test has failed

compareBeziers

public void compareBeziers(String description,
 PolyLine3d reference,
 PolyLine3d candidate,
 int numberOfPoints,
 double epsilon)
                    throws DrawRuntimeException

Compare Bézier curve approximations.

Parameters:

description - String; description of the test

reference - PolyLine3d; reference Bézier curve approximation

candidate - PolyLine3d; candidate Bézier curve approximation

numberOfPoints - int; number of point to compare the curves at, minus one; this method checks at 0% and at 100%

epsilon - double; upper limit of the distance between the two curves

Throws:

DrawRuntimeException - if that happens uncaught; a test has failed

bezierTest3d

@Test
public final void bezierTest3d()
                        throws DrawRuntimeException

Test the various 3d methods in the Bezier class.

Throws:

DrawRuntimeException - when this happens uncaught this test has failed

testExceptions2d

@Test
public void testExceptions2d()

Test the various exceptions of the 2d methods in the Bezier class.

testExceptions3d

@Test
public void testExceptions3d()

testFactorial

@Test
public void testFactorial()
                   throws NoSuchMethodException,
SecurityException,
IllegalAccessException,
IllegalArgumentException,
InvocationTargetException

Test the factorial method.

Throws:

SecurityException - if that happens, this test has failed

NoSuchMethodException - if that happens, this test has failed

InvocationTargetException - if that happens, this test has failed

IllegalArgumentException - if that happens, this test has failed

IllegalAccessException - if that happens, this test has failed
