Q3Vector3D_Cross

You can use the Q3Vector3D_Cross function to determine the cross product of two three-dimensional vectors.

TQ3Vector3D *Q3Vector3D_Cross (
const TQ3Vector3D *v1, 
const TQ3Vector3D *v2, 
TQ3Vector3D *result);

v1

A three-dimensional vector.

v2

A three-dimensional vector.

result

On exit, the cross product of v1 and v2.

DESCRIPTION

The Q3Vector3D_Cross function returns, as its function result and in the result parameter, the cross product of the vectors v1 and v2.
