Q3Vector2D_Cross

You can use the Q3Vector2D_Cross function to determine the cross product of two two-dimensional vectors.

float Q3Vector2D_Cross (
const TQ3Vector2D *v1, 
const TQ3Vector2D *v2);

v1

A two-dimensional vector.

v2

A two-dimensional vector.

DESCRIPTION

The Q3Vector2D_Cross function returns, as its function result, the cross product of the vectors v1 and v2.
