Detailed Description

template<typename _Tp>
class cv::Point3_< _Tp >

Template class for 3D points specified by its coordinates x, y and z.

An instance of the class is interchangeable with the C structure CvPoint2D32f . Similarly to Point_ , the coordinates of 3D points can be converted to another type. The vector arithmetic and comparison operations are also supported.

The following Point3_<> aliases are available:

typedef Point3_<int> Point3i;
typedef Point3_<float> Point3f;
typedef Point3_<double> Point3d;
See also
cv::Point3i, cv::Point3f and cv::Point3d
Examples:
cout_mat.cpp.
