2014 Hambledon Hill formation
|
Reconstruction of the 2014 Hambledon Hill formation | ||
| 1. |
| Draw a circle. Draw the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing up. |
| 3. |
| Construct the inscribed hexagon of circle 1, pointing to the right. |
| 4. |
| Construct a circle centered at the intersection of the righthand side of hexagon 2 and the upper righthand side of hexagon 3, tangent to circle 1 at the near side. |
| 5. |
| Construct a "two-points" circle (defined by the two end-points of a centerline), between the center of circle 4 and its tangent-point with circle 1. |
| 6. |
| Construct a circle concentric to circle 1, passing through the center of circle 5. |
| 7. |
| Copy circle 4 to the center of circle 1, and move this circle (copy and delete original) to its righthand intersection with the horizontal centerline. |
| 8. |
| Construct a circle concentric to circle 1, tangent to circle 7 at the righthand side. |
| 9. |
| Draw three rays of circle 1, from its center to the top and the lower lefthand and righthand angular points of hexagon 2. |
| 10. |
| Copy circle 4 to the intersection of circle 8 and the upper ray 9, and move this circle to its own corresponding intersection. |
| 11. |
| Repeat step 10 two times, with respect to the corresponding intersections of circle 8 and the other two rays 9. |
| 12. |
| Copy circle 5 to the center of circle 1. |
| 13. |
| Draw the connecting line between the intersections of circle 12 and the two lower rays 9. |
| 14. |
| Construct a "two-points" circle between the center of circle 1 and the intersection of line 13 and the vertical centerline. |
| 15. |
| Copy circle 14 seven times, to the center of circle 1, and to the angular points of hexagon 2. See detail. |
|
| ||
| 16. |
| Construct six pairs of parallel lines, each pair tangent to the central circle 15, and tangent to each one of the other circles 15, all at both sides. See detail. |
|
| ||
| 17. |
| Circles 1, 6, 8, 10 and 11, and lines 16, are used for the final reconstruction. |
| 18. |
| Remove all parts not visible within the formation itself. |
| 19. |
| Colour all areas corresponding to standing... |
| 20. |
| ...or to flattened crop, and finish the reconstruction of the 2014 Hambledon Hill formation. |
| 21. |
| The final result, matched with the aerial image. |
