Q3Point3D_TransformQuaternion

You can use the Q3Point3D_TransformQuaternion function to transform a point by a quaternion.

TQ3Point3D *Q3Point3D_TransformQuaternion (
const TQ3Point3D *point, 
const TQ3Quaternion *quaternion, 
TQ3Point3D *result);

point

A three-dimensional point.

quaternion

A quaternion.

result

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

DESCRIPTION

The Q3Point3D_TransformQuaternion function returns, as its function result and in the result parameter, a three-dimensional point that is the result of transforming the point specified by the point parameter using the quaternion specified by the quaternion parameter.
