Q3Param2D_Vector2D_Add

You can use the Q3Param2D_Vector2D_Add function to add a two-dimensional vector to a two-dimensional parametric point.

TQ3Param2D *Q3Param2D_Vector2D_Add (
const TQ3Param2D *param2D, 
const TQ3Vector2D *vector2D, 
TQ3Param2D *result);

param2D

A two-dimensional parametric point.

vector2D

A two-dimensional vector.

result

On exit, a two-dimensional point that is the result of adding vector2D to param2D.

DESCRIPTION

The Q3Param2D_Vector2D_Add function returns, as its function result and in the result parameter, the two-dimensional parametric point that is the result of adding the vector vector2D to the parametric point param2D.
