For a panel that is not rectangular, the distribution is described
in following diagram.
First, the CG of the polygon is calculated. Then, each corner is
connected to the CG to form triangles as shown. For each triangle,
a vertical line is drawn from the CG to the opposite side. If the
point of intersection of the vertical line and the side falls outside
the triangle, the area of that triangle will be calculated and an
equivalent uniform distributed load will be applied on that side.
Otherwise a triangular load will be applied on the side.
