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.LHomogenousCoordsAdapter.__init__ ( LHomogenousCoordsAdapter  va)

Contructs a copy of the LHomogenousCoordsAdapter instance va.

Parameters
vaThe LHomogenousCoordsAdapter instance to copy.

◆ __init__() [2/2]

None CDPL.Math.LHomogenousCoordsAdapter.__init__ ( LVectorExpression  v)

Constructs the adapter wrapping v.

Parameters
vThe vector to be viewed as its homogeneous-coordinate extension.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.LHomogenousCoordsAdapter.getObjectID ( )

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

Different Python LHomogenousCoordsAdapter 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 LHomogenousCoordsAdapter 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.
