Point3d Constructor 
Name  Description  

Point3d(Point3d) 
Initializes a new point by copying coordinates from another point.
 
Point3d(Point3f) 
Initializes a new point by copying coordinates from a singleprecision point.
 
Point3d(Point4d) 
Initializes a new point by copying coordinates from a fourdimensional point.
The first three coordinates are divided by the last one.
If the W (fourth) dimension of the input point is zero, then it will be just discarded.
 
Point3d(Vector3d) 
Initializes a new point by copying coordinates from the components of a vector.
