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
