20 Subtracting Points

20 Q3Point3D_Subtract

You can use the Q3Point3D_Subtract function to subtract one three-dimensional point from another.

TQ3Vector3D *Q3Point3D_Subtract (
const TQ3Point3D *p1, 
const TQ3Point3D *p2, 
TQ3Vector3D *result);
p1 A three-dimensional point.
p2 A three-dimensional point.
result On exit, a three-dimensional vector that is the result of subtracting the point p2 from p1.

DESCRIPTION


The Q3Point3D_Subtract function returns, as its function result and in the result parameter, the three-dimensional vector that is the result of subtracting the point p2 from p1.
