Q3Point3D_CrossProductTri
You can use the Q3Point3D_CrossProductTri function to determine the cross product of the two vectors defined by three three-dimensional points.
TQ3Vector3D *Q3Point3D_CrossProductTri (
const TQ3Point3D *point1,
const TQ3Point3D *point2,
const TQ3Point3D *point3,
TQ3Vector3D *crossVector);
point1
- A three-dimensional point.
point2
- A three-dimensional point.
point3
- A three-dimensional point.
crossVector
- On exit, the cross product of the two vectors determined by subtracting
point2 from point1 and point3 from point1.
DESCRIPTION
The Q3Point3D_CrossProductTri function returns, as its function result and in the crossVector parameter, the cross product of the two vectors determined by subtracting point2 from point1 and point3 from point2.
