Q3Vector3D_TransformQuaternion

You can use the Q3Vector3D_TransformQuaternion function to transform a vector by a quaternion.

TQ3Vector3D *Q3Vector3D_TransformQuaternion (
const TQ3Vector3D *vector, 
const TQ3Quaternion *quaternion, 
TQ3Vector3D *result);

vector

A three-dimensional vector.

quaternion

A quaternion.

result

On exit, a three-dimensional vector that is the result of transforming the specified vector by the specified quaternion.

DESCRIPTION

The Q3Vector3D_TransformQuaternion function returns, as its function result and in the result parameter, a three-dimensional vector that is the result of transforming the vector specified by the vector parameter using the quaternion specified by the quaternion parameter.
