A method is disclosed. The method includes receiving a first polygon, receiving a second polygon, calculating a vector joining a centroid of the first polygon and a centroid of the second polygon, retrieving vertices of each polygon that are farthest from the other polygon in the direction of the vector towards the other polygon, performing a view frustrum from each vertex retrieved for the first polygon to the centroid of the first polygon, performing a clipping operation on the second polygon and determining if the second polygon intersects the view frustrum of one or more of the vertices of the first polygon. |
