Detailed Description

Vector expression that exposes a vector as its homogeneous-coordinate extension by appending an implicit 1 at the end.

Constructor & Destructor Documentation

__init__() [1/2]

None CDPL.Math.ConstLHomogenousCoordsAdapter.__init__

(

ConstLHomogenousCoordsAdapter

va

)

Contructs a copy of the ConstLHomogenousCoordsAdapter instance va.

Parameters

va	The ConstLHomogenousCoordsAdapter instance to copy.

__init__() [2/2]

None CDPL.Math.ConstLHomogenousCoordsAdapter.__init__

(

ConstLVectorExpression

v

)

Constructs the adapter wrapping v.

Parameters

v	The vector to be viewed as its homogeneous-coordinate extension.

Member Function Documentation

getObjectID()

int CDPL.Math.ConstLHomogenousCoordsAdapter.getObjectID

(

)

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

Different Python ConstLHomogenousCoordsAdapter 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 ConstLHomogenousCoordsAdapter 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.

isEmpty()

bool CDPL.Math.ConstLHomogenousCoordsAdapter.isEmpty

(

)

Tells whether the view is empty (always False).

Returns

False.

getSize()

int CDPL.Math.ConstLHomogenousCoordsAdapter.getSize

(

)

Returns the dimensionality of the view (wrapped vector size + 1).

Returns

The view size.

getElement()

int CDPL.Math.ConstLHomogenousCoordsAdapter.getElement

(

int

i

)

Returns the element at index i of the view.

Parameters

i	The zero-based index within the view.

Returns

The value of the element.

toArray()

object CDPL.Math.ConstLHomogenousCoordsAdapter.toArray

(

)

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

Returns

The generated numpy.ndarray object.
