Reconstruction of the
2015 Pontecurone, Italy formation |
|
1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines.
|
|
2. |
| Construct the inscribed regular 16-sided polygon of circle 1, pointing up.
|
|
3. |
| Draw the sixteen rays of polygon 2, from the center of circle 1 to the angular points. Number these rays clockwise 1 - 16, starting from the one next to the top to the right.
|
|
4. |
| Construct the inscribed square of circle 1, pointing up.
|
|
5. |
| Construct the inscribed square of circle 1, with horizontal and vertical sides.
|
|
6. |
| Construct a square concentric to circle 1, with one angular point at the intersection of ray 3 nr. 1 and square 5.
|
|
7. |
| Construct a square concentric to circle 1, with one angular point at the intersection of ray 3 nr. 15 and square 5.
|
|
8. |
| Construct a circle centered at the intersection of ray 3 nr. 1 and square 7, tangent to the vertical centerline.
|
|
9. |
| Copy circle 8 to the center of circle 1.
|
|
10. |
| Construct a circle centered at the intersection of ray 3 nr. 1 and square 5, passing through the intersection (tangent point) of circle 8 and square 5.
|
|
11. |
| Copy circle 10 to the lower intersection of ray 3 nr. 1 and circle 8.
|
|
12. |
| Construct a circle concentric to circle 1, tangent to circle 11 at the lower side.
|
|
13. |
| Construct a "two-points circle" (defined by the two end-points of a centerline) between the center of circle 9 and its righthand intersection with the horizontal centerline.
|
|
14. |
| Copy circle 13 to the center of circle 1.
|
|
15. |
| Construct a "two-points circle" between the center of circle 14 and its righthand intersection with the horizontal centerline.
|
|
16. |
| Copy circle 15 to the righthand intersection of circle 1 and the horizontal centerline.
|
|
17. |
| Construct a circle concentric to circle 1, tangent to circle 16 at the righthand side.
|
|
18. |
| Circles 1, 9, 12, 14, and 17, and squares 4, 5, 6, and 7, together make up the final reconstruction.
|
|
19. |
| Colour all areas corresponding to standing...
|
|
20. |
| ...or to flattened crop, and finish the reconstruction of the 2015 Pontecurone, Italy formation.
|
|
21. |
| The final result, matched with the aerial image.
