20 Adding and Subtracting Points and Vectors

20 Q3Param2D_Vector2D_Subtract

You can use the Q3Param2D_Vector2D_Subtract function to subtract a two-dimensional vector from a two-dimensional parametric point.

TQ3Param2D *Q3Param2D_Vector2D_Subtract (
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 parametric point that is the result of subtracting vector2D from param2D.

DESCRIPTION


The Q3Param2D_Vector2D_Subtract function returns, as its function result and in the result parameter, the two-dimensional parametric point that is the result of subtracting the vector vector2D from the point param2D.
