static void testIfBothTransformationsProduceSameResults ( void )

This test basically is just a sanity check and should be PASSED exactly when both testTransferItkTransformToVtkMatrix and testIfPointIsTransformedAsExpected are PASSED. Tests if we get the same result by using the AffineTransform3D to transform a point or the vtkMatrix4x4 which we got by applying the TransferItkTransformToVtkMatrix function. This test e.g. ensures we made no mistake in our reference results.

create both a AffineTransform3D and let this AffineTransform describe also a homogenous 4x4 Matrix vtkMatrix by using our transfer method

Let a point be transformed by the AffineTransform3D and by homogenMatrix

◆ testIfPointIsTransformedAsExpected()

static void testIfPointIsTransformedAsExpected ( void )

static

This first test basically assures that we understand the usage of AffineTransform3D correct. Meaning that the rotation is set by SetMatrix and the translation is set by SetOffset

construct the transformation

Let a point be transformed by the AffineTransform3D

assert that the transformation was successful
