Detailed Description

Translation matrix holding integer values of type long.

Constructor & Destructor Documentation

◆ __init__() [1/2]

None CDPL.Math.LTranslationMatrix.__init__ ( LTranslationMatrix  m)

Constructs a copy of the translation matrix m.

Parameters
mThe translation matrix to copy.

◆ __init__() [2/2]

None CDPL.Math.LTranslationMatrix.__init__ ( int  n,
int   tx = 0,
int   ty = 0,
int   tz = 0 
)

Constructs an N×N translation matrix with the supplied per-axis translation components.

Parameters
nThe matrix dimension N.
txThe x-axis translation.
tyThe y-axis translation.
tzThe z-axis translation.

Member Function Documentation

◆ set()

None CDPL.Math.LTranslationMatrix.set ( int   tx = 0,
int   ty = 0,
int   tz = 0 
)

Sets the per-axis translation components.

Parameters
txThe x-axis translation.
tyThe y-axis translation.
tzThe z-axis translation.

◆ getObjectID()

int CDPL.Math.LTranslationMatrix.getObjectID ( )

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python LTranslationMatrix instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two LTranslationMatrix instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns
The numeric ID of the internally referenced C++ class instance.

◆ getSize1()

int CDPL.Math.LTranslationMatrix.getSize1 ( )

Returns the dimension N (the row count).

Returns
N.

◆ getSize2()

int CDPL.Math.LTranslationMatrix.getSize2 ( )

Returns the dimension N (the column count).

Returns
N.

◆ isEmpty()

bool CDPL.Math.LTranslationMatrix.isEmpty ( )

Tells whether the matrix is empty (size zero).

Returns
True if N is zero, and False otherwise.

◆ getElement()

int CDPL.Math.LTranslationMatrix.getElement ( int  i,
int  j 
)

Returns the translation matrix element at (i, j).

Parameters
iThe zero-based row index.
jThe zero-based column index.
Returns
1 on the diagonal, the corresponding translation component in the last column (rows 0-2) and 0 elsewhere.
Exceptions
Base.IndexErrorif either index is out of range.

◆ toArray()

object CDPL.Math.LTranslationMatrix.toArray ( )

Converts the LTranslationMatrix instance into a corresponding numpy.ndarray object.

Returns
The generated numpy.ndarray object.

◆ assign()

LTranslationMatrix CDPL.Math.LTranslationMatrix.assign ( LTranslationMatrix  m)

Copy-assigns the dimension and the translation components from m.

Parameters
mThe source translation matrix.

◆ swap()

None CDPL.Math.LTranslationMatrix.swap ( LTranslationMatrix  m)

Swaps the dimension and the translation components with m.

Parameters

◆ __call__()

◆ __getitem__()

int CDPL.Math.LTranslationMatrix.__getitem__ ( tuple  ij)

Returns the translation matrix element at (i, j).

Parameters
iThe zero-based row index.
jThe zero-based column index.
Returns
1 on the diagonal, the corresponding translation component in the last column (rows 0-2) and 0 elsewhere.
Exceptions
Base.IndexErrorif either index is out of range.
