Reconstruction of the
2010 Fosbury formation
1. Draw a circle. Draw and extend the horizontal and vertical centerlines.
2. Construct the circumscribed hexagon (regular six-sided polygon) of circle 1, pointing to the right.
3. Draw the three diagonals of hexagon 2 through the center of circle 1.
4. Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its upper intersection with the vertical centerline.
5. Construct a circle concentric to circle 1, passing through the upper righthand intersection of diagonals 3 and circle 4.
6. Construct the inscribed hexagon of circle 5, pointing to the right.
7. Copy circle 4 to the center of circle 1.
8. Construct the circumscribed hexagon of circle 7, pointing to the right.
9. Draw the connecting line between the righthand angular points of hexagons 6 and 8. Divide this line into nine equal parts.
10. Construct eight circles, all concentric to circle 1, passing through division-points 9.
11. Construct the eight inscribed hexagons of circles 10, all pointing to the right.
12. Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, passing through the righthand angular point of hexagon 2.
13. Copy circle 12 to the righthand angular point of hexagon 8.
14. Construct a circle concentric to circle 1, tangent to circle 13 at the lefthand side.
15. Construct the inscribed hexagon of circle 14, pointing to the right.
16. Construct a "two-points" circle between the righthand angular points of hexagon 8 and innermost hexagon 11.
17. Copy circle 16 to the center of circle 1.
18. Copy both lefthand sides of all hexagons 6, 8 and 11 as a whole, from the lefthand angular point of hexagon 6 to the righthand intersection of circle 17 and the horizontal diagonal 3 (and trim off all parts outside hexagon 6).
19. Copy the set of lines 18 as a whole two times, to corresponding intersections of circle 17 and the other diagonals, while rotating about its center over 120° and 240° respectively, as shown.
20. Extend the six lines 18 and 19 nearest to the center of circle 1 up to the opposite side of hexagon 15, as shown.
21. Construct a circle centered at the lefthand intersection and passing through the righthand intersection, both of circle 16 with the horizontal centerline.
22. Copy circle 21 to the righthand angular point of hexagon 15.
23. Construct a circle concentric to circle 1, tangent to circle 22 at the righthand side.
24. Construct the inscribed hexagon of circle 23, pointing to the right.
25. Construct a "two-points" circle between the righthand angular point of hexagon 15 and the center of circle 16.
26. Copy circle 25 to the righthand angular point of hexagon 2.
27. Construct a "two-points" circle between the center of circle 26 and its lefthand intersection with the horizontal centerline.
28. Construct a circle concentric to circle 1, tangent to circle 27 at the lefthand side.
29. Construct the inscribed hexagon of circle 28, pointing to the right.
30. Construct a circle concentric to circle 1, passing through the center of circle 27.
31. Construct the inscribed hexagon of circle 30, pointing to the right.
32. Construct a circle centered at the righthand angular point of hexagon 29, tangent to the righthand sides of hexagon 31.
33. Construct a circle concentric to circle 32, tangent to the righthand sides of hexagon 2.
34. Copy circles 32 and 33 five times, to the other angular points of hexagon 29.
35. Hexagons 2, 6, 8, 11, 15, 24, 29 and 31, lines 18, 19 and 20, and circles 32, 33 and 34, are used for the final reconstruction.
36. Remove all parts not present within the formation itself.
37. Colour all areas corresponding to standing...
38. ...or to flattened crop, and finish the reconstruction of the 2010 Fosbury formation.
39. The final result, matched with the aerial image.
