Polygon (Link)

The fundamental object for the board game project is the Polygon. The idea is that one simply provides vertex locations (x1,y1) through (xn,yn) and the methods of the class render a beveled polygon under the given lighting conditions. Of course, not all possible vertex locations will lead to a valid polygon; there are a few conditions that must be met in order for the choice of vertices to be acceptable:

1. All of the provided vertex locations are distinct, i.e. i ≠ j implies xi ≠ xj or yi ≠ yj 

2. The line segments defining the perimeter of the polygon only intersect trivially, i.e. if two line segments intersect then they only intersect at a single point and that point is one of the provided vertex locations

3. The vertices defining the polygon's perimeter must traverse a counter clockwise path around the interior of the polygon (although in practice if they are provided as going clockwise then the vertex ordering is simply reversed by the Polygon class)

Once the Polygon object has been initialized, one must call the preprocessBevelInfo and preprocessSunInfo methods to apply settings relevant to the rendering of a uniform-width bevel along the perimeter of the polygon. Beyond this, the user can provide an RGB object as an argument in the render method in order to apply a tint to the overall color of the polygon image. The images in the following examples show off the various render configuration options in more detail:
