Detailed Description

Quaternion expression that exposes a 4-element vector as a quaternion (component indices 0-3 map to C1-C4).

Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Math.ULVectorQuaternionAdapter.__init__ ( ULVectorQuaternionAdapter va )

Contructs a copy of the ULVectorQuaternionAdapter instance va.

Parameters

va	The `ULVectorQuaternionAdapter` instance to copy.

◆ init() [2/2]

None CDPL.Math.ULVectorQuaternionAdapter.__init__ ( ULVectorExpression v )

Constructs the adapter wrapping the 4-element vector v.

Parameters

v	The 4-element vector to be viewed as a quaternion.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.ULVectorQuaternionAdapter.getObjectID ( )

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

Different Python ULVectorQuaternionAdapter 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 ULVectorQuaternionAdapter 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.
