  A novel method has been introduced to solve a point inclusion in a polygon
problem. The method is applicable to convex as well as non-convex polygons
which are not self-intersecting. The introduced method is independent of
rounding off errors, which gives it a leverage over some methods prone to this
problem. A brief summary of the methods used to solve this problem is presented
and the introduced method is discussed. The introduced method is compared to
other existing methods from the point of view of computational cost. This
method was inspired from a Computational Fluid Dynamics (CFD) application using
grids not fitted to the simulated objects.
