How to test if a point is inside of a convex polygon in 2D integer coordinates?

Question

The polygon is given as a list of Vector2I objects (2 dimensional, integer coordinates). How can i test if a given point is inside? All implementations i found on the web fa

Answer 1

The pointPolygonTest function in openCV " determines whether the point is inside a contour, outside, or lies on an edge": http://docs.opencv.org/modules/imgproc/doc/structural_analysis_and_shape_descriptors.html?highlight=pointpolygontest#pointpolygontest
