  • MT_2D_2x3

    public static final MatrixType MT_2D_2x3

    A 2D affine transformation matrix of 2 rows and 3 columns containing the following values:

    mxx, mxy, tx,
     myx, myy, ty

  • MT_2D_3x3

    public static final MatrixType MT_2D_3x3

    A 2D transformation matrix of 3 rows and 3 columns. For affine transforms the last line is constant, so the matrix contains the following values:

    mxx, mxy, tx,
     myx, myy, ty,
       0,   0,  1

  • MT_3D_3x4

    public static final MatrixType MT_3D_3x4

    A 3D affine transformation matrix of 3 rows and 4 columns containing the following values:

    mxx, mxy, mxz, tx,
     myx, myy, myz, ty,
     mzx, mzy, mzz, tz

  • MT_3D_4x4

    public static final MatrixType MT_3D_4x4

    A 3D transformation matrix of 4 rows and 4 columns. For affine transforms the last line is constant, so the matrix contains the following values:

    mxx, mxy, mxz, tx,
     myx, myy, myz, ty,
     mzx, mzy, mzz, tz,
       0,   0,   0,  1

• Method Detail

  • values

    public static MatrixType[] values()

    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

    for (MatrixType c : MatrixType.values())
        System.out.println(c);

    Returns:

    an array containing the constants of this enum type, in the order they are declared

  • valueOf

    public static MatrixType valueOf(String name)

    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

    Parameters:

    name - the name of the enum constant to be returned.

    Returns:

    the enum constant with the specified name

    Throws:

    IllegalArgumentException - if this enum type has no constant with the specified name

  • elements

    public int elements()

    Returns the number of elements in the matrix of this type.

    Returns:

    the number of elements in the matrix of this type

  • rows

    public int rows()

    Returns the number of rows in the matrix of this type.

    Returns:

    the number of rows in the matrix of this type

  • columns

    public int columns()

    Returns the number of columns in the matrix of this type.

    Returns:

    the number of columns in the matrix of this type

  • is2D

    public boolean is2D()

    Specifies if this is a 2D transformation matrix

    Returns:

    true if this is a 2D transformation matrix, false if this is a 3D transformation matrix
