Reconstruction of the
2015 Blackhorse Lane formation |
|
1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines.
|
|
2. |
| Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing down.
|
|
3. |
| Draw the ray of hexagon 2, from the center of circle 1 to its lower lefthand angular point.
|
|
4. |
| Draw the ray of hexagon 2, from the center of circle 1 to its lower righthand angular point.
|
|
5. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its lower intersection with the vertical centerline.
|
|
6. |
| Construct two "two-points" circles, between the center of circle 5 and each of its intersections with the vertical centerline.
|
|
7. |
| Construct three circles concentric to circle 1, passing through the centers of circles 5 and 6.
|
|
8. |
| Copy circles 7 to the lower intersection of circle 1 and the vertical centerline.
|
|
9. |
| Draw three parallel lines, from the intersections of circles 7 and line 3 to the intersections of circles 8 and the lower righthand side of hexagon 2.
|
|
10. |
| Draw three parallel lines, from the intersections of circles 7 and line 4 to the intersections of circles 8 and the lower lefthand side of hexagon 2.
|
|
11. |
| Draw a line from the center of circle 1 to its lower intersection with the vertical centerline.
|
|
12. |
| Draw three vertical lines from the intersections of lines 9 and line 3 to the intersections of lines 10 and the lower lefthand side of hexagon 2.
|
|
13. |
| Draw three vertical lines from the intersections of lines 10 and line 4 to the intersections of lines 9 and the lower righthand side of hexagon 2.
|
|
14. |
| Draw a line from the center of circle 1 to the intersection of the upper line 9 and the middle line 10.
|
|
15. |
| Construct a circle centered at the intersection of the upper line 10 and line 14, tangent to the innermost circle 7 at the lower righthand side.
|
|
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. |
| Construct a "two-points" circle between the center of circle 15 and its lower intersection with line 14.
|
|
19. |
| Copy circle 18 to the lower righthand angular point of hexagon 2.
|
|
20. |
| Copy circle 18 to the center of circle 1.
|
|
21. |
| Draw a line parallel to line 4, tangent to circles 19 and 20 at the lower lefthand sides.
|
|
22. |
| Copy circle 18 to the lower angular point of hexagon 2.
|
|
23. |
| Draw a line parallel to the lower righthand side of hexagon 2, tangent to circles 19 and 22 at the upper lefthand sides.
|
|
24. |
| Circles 1 and 17, hexagon 2, and lines 3, 4, 9, 10, 11, 12, 13, 21, and 23, are used for the final reconstruction.
|
|
25. |
| Remove all parts not visible within the formation itself.
|
|
26. |
| Colour all areas corresponding to standing...
|
|
27. |
| ...or to flattened crop, and finish the reconstruction of the 2015 Blackhorse Lane formation.
|
|
28. |
| The final result, matched with the aerial image.
