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.ConstDHomogenousCoordsAdapter.__init__ ( ConstDHomogenousCoordsAdapter va )

Contructs a copy of the ConstDHomogenousCoordsAdapter instance va.

Parameters

va	The `ConstDHomogenousCoordsAdapter` instance to copy.

◆ init() [2/2]

None CDPL.Math.ConstDHomogenousCoordsAdapter.__init__ ( ConstDVectorExpression 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.ConstDHomogenousCoordsAdapter.getObjectID ( )

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

Different Python ConstDHomogenousCoordsAdapter 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 ConstDHomogenousCoordsAdapter 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.ConstDHomogenousCoordsAdapter.isEmpty ( )

Tells whether the view is empty (always False).

Returns: False.

◆ getSize()

int CDPL.Math.ConstDHomogenousCoordsAdapter.getSize ( )

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

Returns: The view size.

◆ getElement()

float CDPL.Math.ConstDHomogenousCoordsAdapter.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.ConstDHomogenousCoordsAdapter.toArray ( )

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

Returns: The generated numpy.ndarray object.

See also: [NUMPY]

◆ getData()

ConstDVectorExpression CDPL.Math.ConstDHomogenousCoordsAdapter.getData ( )

Returns the wrapped vector.

Returns: The wrapped vector closure.

◆ eq() [1/2]

bool CDPL.Math.ConstDHomogenousCoordsAdapter.__eq__ ( ConstDHomogenousCoordsAdapter va )

Returns the result of the comparison operation self == va.

Parameters

va	The `ConstDHomogenousCoordsAdapter` instance to be compared with.

Returns: The result of the comparison operation.

◆ eq() [2/2]

bool CDPL.Math.ConstDHomogenousCoordsAdapter.__eq__ ( ConstDVectorExpression e )

Returns the result of the comparison operation self == e.

Parameters

e	The `ConstDVectorExpression` instance to be compared with.

Returns: The result of the comparison operation.

◆ ne() [1/2]

bool CDPL.Math.ConstDHomogenousCoordsAdapter.__ne__ ( ConstDHomogenousCoordsAdapter va )

Returns: The result of the comparison operation.

◆ call()

float CDPL.Math.ConstDHomogenousCoordsAdapter.__call__ ( int i )

Returns the element at index i of the view.

At index getSize() - 1 the method returns the extension element (initialized to 1). At lower indices it returns the corresponding element of the wrapped vector.

Parameters

i	The zero-based index within the view.

Returns: The value of the element.

◆ getitem()

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

Returns: The view size.

◆ str()

str CDPL.Math.ConstDHomogenousCoordsAdapter.__str__ ( )

Returns a string representation of the ConstDHomogenousCoordsAdapter instance.

Returns: The generated string representation.

◆ pos()

ConstDHomogenousCoordsAdapter CDPL.Math.ConstDHomogenousCoordsAdapter.__pos__ ( )

Returns self.

Returns: self.

◆ neg()

ConstDVectorExpression CDPL.Math.ConstDHomogenousCoordsAdapter.__neg__ ( )

Returns the result of the operation self * -1.

Returns: A ConstDVectorExpression instance holding the result of the element negation.
