Answer 1

Answer 2

Inside-Outside test in computer graphics is:

• Given a polygon and a point 'p', to find 'p' whether it lies inside the polygon or not. The points lying on the border are considered as inside.
• The simple approach to check whether a point is inside or outside:

        1.) Draw a horizontal line to the right of each point and extend it to

            infinity.

        2.) Count the number of times the lines intersect with polygon edges.

        3.) A point lies inside the polygon if either count of intersections is odd

             or point lies on the edge of polygon. If none of the conditions are

             true, then point lies outside.
