Q3Vector3D_To2D

You can use the Q3Vector3D_To2D function to convert a three-dimensional vector to a two-dimensional vector.

TQ3Vector2D *Q3Vector3D_To2D (
const TQ3Vector3D *vector3D, 
TQ3Vector2D *result);

vector3D

A three-dimensional vector.

result

On exit, a two-dimensional vector.

DESCRIPTION

The Q3Vector3D_To2D function returns, as its function result and in the result parameter, the two-dimensional vector that corresponds to the three-dimensional vector vector3D.
