In this formula, the “shoelace” inside absolute value bars is meant to represent the difference between the sums of the diagonal products. To make sense of the formula, we first explore the vec-tor cross product using triangles and quadrilaterals.

Shoelace formula

Some articles had The above function moves the polygon to origin and adds angles to each corner. The area calculated will still be correct (when using PolygonArea(PolygonSort(corners))). A while back, I learned about the shoelace formula explained here by Mathologer. Basically, it takes the coordinates of a polygon and uses determinants to find the area of that polygon. I was wondering if a similar algorithm exists that allows one to find the volume of a solid given the coordinates of its vertices. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Shoelace Given a polygon with vertices at we may compute the area of the polygonal region by setting and computing: To start, recall that if , then . Hence Green’s Theorem states: This means we can compute the area of the region , by evaluating the line integral on the right along the polygonal boundary .

Fig.3. When I tried both of your functions with 500 coordinate pairs, shoelace_formula_3 was twice as fast (115 microseconds) as shoelace_formula (321 microseconds). – jakub Dec 10 '16 at 16:15 1 And if you do x, y = zip(*polygonBoundary) outside of the function and include x and y as function parameters, it runs in 93.7 microseconds.
