API Reference Guide > Vector Component API Reference > Vector Component Structures Reference > IGVectPoint3DEx

This structure declares an extended three-dimensional point. The extended point contains one additional field that is used as a weight for NURBS surfaces.

Declaration:

 
Copy Code
typedef struct tag_IGVectPoint3DEx
{
        VECT_REAL m_x;
        VECT_REAL m_y;
        VECT_REAL m_z;
        VECT_REAL m_w;
} IGVectPoint3DEx;

Members:

Name Type Description
m_x VECT_REAL x coordinate.
m_y VECT_REAL y coordinate.
m_z VECT_REAL z coordinate.
m_w VECT_REAL Weight of the point.
