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.ULHomogenousCoordsAdapter.__init__ ( ULHomogenousCoordsAdapter va )

Contructs a copy of the ULHomogenousCoordsAdapter instance va.

Parameters

va	The `ULHomogenousCoordsAdapter` instance to copy.

◆ init() [2/2]

None CDPL.Math.ULHomogenousCoordsAdapter.__init__ ( ULVectorExpression 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.ULHomogenousCoordsAdapter.getObjectID ( )

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

Different Python ULHomogenousCoordsAdapter 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 ULHomogenousCoordsAdapter 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.
