Create a contour manually

How to create a contour, by sending manually the x,y points of the contours (in my own function) instead to use findcontours?
Thank you,

a contour can be a std::vector<cv::Point>, or a Mat of suitable shape.

a list of contours is a vector of those.

browse the examples. here’s one: OpenCV: samples/cpp/contours2.cpp

don’t expect there to be an example that precisely does what you need.
