TransformationMatrix

public TransformationMatrix(Triangle P,
                            Triangle Q)

Method Detail

triangle_transform

public boolean triangle_transform(Triangle P,
                                  Triangle Q)

ComPute the transformation matrix from triangle P. to triangle Q. Return TRUE if the transformation is Possible, FALSE if triangle P is degenerate, or segment (Q1, Q2) is degenerate. Entry: Q.1, Q.2, Q.3: vertices for triangle Q. P.1, P.2, P.3: vertices for triangle P. Exit: Trans: resulting transformation matrix.

print

FEQUAL

public boolean FEQUAL(double V1,
                      double V2)

convert
