C#
public class Posit

The class implements an algorithm for 3D object's pose estimation from it's 2D coordinates obtained by perspective projection, when the object is described none coplanar points. The idea of the implemented math and algorithm is described in "Model-Based Object Pose in 25 Lines of Code" paper written by Daniel F. DeMenthon and Larry S. Davis (the implementation of the algorithm is almost 1 to 1 translation of the pseudo code given by the paper, so should be easy to follow).

Note:At this point the implementation works only with models described by 4 points, which is the minimum number of points enough for 3D pose estimation.

Blue Winter Warm House Slippers Indoor Slipper Fleece Dark Women's Flannel Plush Home Long Clogs Note:The 4 model's point must not be coplanarAnkle Bootie Gwen Very Women's Volatile Taupe Bgqw4Ox, i.e. must not reside all within same planer.
