Detailed Description

A memory-efficient pure-real quaternion with component values of type double.

Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Math.DRealQuaternion.__init__ ( DRealQuaternion q )

Constructs a copy of the real quaternion q (possibly converting the component type).

Parameters

q	The real quaternion to copy.

◆ init() [2/2]

None CDPL.Math.DRealQuaternion.__init__ ( float r )

Constructs the real quaternion with the supplied real component.

Parameters

r	The real component value.

Member Function Documentation

◆ set()

DRealQuaternion CDPL.Math.DRealQuaternion.set ( float r = 0.0 )

Assigns the scalar r to the real component.

Parameters

r	The scalar value.

Returns: self.

◆ getObjectID()

int CDPL.Math.DRealQuaternion.getObjectID ( )

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

Different Python DRealQuaternion 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 DRealQuaternion 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.

Returns the imaginary component C3 (always zero for a real quaternion).

Returns: The zero element.

◆ getC4()

Returns the imaginary component C4 (always zero for a real quaternion).

Returns: The zero element.

◆ toArray()
