Reconstruction of the 2020 Vimy (France) 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 up. |
| 3. |
| Construct the inscribed circle of hexagon 2. |
| 4. |
| Construct the inscribed square of circle 1, with horizontal and vertical sides. |
| 5. |
| Construct the inscribed circle of square 4. |
| 6. |
| Construct the inscribed equilateral triangle of circle 1, pointing up. |
| 7. |
| Construct the inscribed circle of triangle 6. |
| 8. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the righthand intersection of circle 7, and the intersection of the righthand side of triangle 6, both with the horizontal centerline. |
| 9. |
| Construct a "two-points" circle between the center of circle 8 and its lefthand intersection with the horizontal centerline. |
| 10. |
| Copy circle 9 to the center of circle 1. |
| 11. |
| Construct a circle, passing through the upper lefthand and righthand angular points of square 4, and tangent to circle 10 at the upper side. |
| 12. |
| Repeat step 11 three times, with respect to the other sides of square 4. |
| 13. |
| Construct a "two-points" circle between the upper intersections of circles 7 and 11 with the vertical centerline. |
| 14. |
| Repeat step 13 three times, with respect to circles 7 and 12. |
| 15. |
| Construct a circle concentric to circle 1, tangent to circle 11 at the upper side. |
| 16. |
| Copy circle 8 to the righthand intersection of circle 3 and the horizontal centerline. |
| 17. |
| Construct a circle concentric to circle 1, tangent to circle 16 at the lefthand side. |
| 18. |
| Circles 1, 3, 5, 11, 12, 13, 14, 15, and 17, are used for the final reconstruction. |
| 19. |
| Remove all parts not visible within the formation itself. |
| 20. |
| Colour all areas corresponding to standing... |
| 21. |
| ...or to flattened crop, and finish the reconstruction of the 2020 Vimy (France) formation. |
| 22. |
| The final result, matched with two aerial images. |
