Detailed Description

This class represents a rotation quaternion in 3D space.

Remarks

OdGeQuaternion may be viewed as an array[4] of doubles.

Corresponding C++ library: TD_Ge

<group OdGe_Classes>

Constructor & Destructor Documentation

OdGeQuaternion() [1/2]

OdGeQuaternion::OdGeQuaternion ( )

inline

Quaternions are used to specify the rotations necessary for 3d planar orientation. It stores 4 Double variables w, x, y, and z.

Remarks

When called with no arguments, constructs a zero quaternion.
