2021 Stanton St Bernard formation
|
Reconstruction of the 2021 Stanton St Bernard formation | ||
| 1. |
| Draw a circle. Draw the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed octagon (regular 8-sided polygon) of circle 1, pointing up. |
| 3. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its righthand intersection with the horizontal centerline. |
| 4. |
| Draw the ray of octagon 2 from the center to the upper righthand angular point. |
| 5. |
| Draw the connecting line between the center of circle 3 and the upper righthand angular point of octagon 2. |
| 6. |
| Draw the connecting line between the righthand angular point of octagon 2 and the intersection of circle 3 and line 5. |
| 7. |
| Construct a line from the center of circle 3, perpendicular to the righthand side, above the horizontal centerline, of octagon 2, and extend this line to the right upto circle 3. |
| 8. |
| Construct a "two-points" circle between the intersections of line 7 with circle 3 and octagon 2. |
| 9. |
| Copy circle 8 two times, to both end-points of line 4. |
| 10. |
| Construct a line parallel to line 4, tangent to circles 9 at the lower righthand sides. |
| 11. |
| Copy circle 8 to the lower end-point of line 6. |
| 12. |
| Construct a line parallel to the horizontal centerline, tangent to lower circle 9 and circle 11 at the upper sides. |
| 13. |
| Copy circle 8 to the center of circle 3. |
| 14. |
| Construct two lines parallel to line 5, tangent to upper circle 9 and circle 13 at both sides. |
| 15. |
| Copy circle 8 to the upper end-point of line 6. |
| 16. |
| Construct a line parallel to line 6, tangent to circles 11 and 15 at the lower lefthand sides. |
| 17. |
| Remove all redundant parts from lines 10, 12, 14, and 16, such that... |
| 18. |
| ...these patterns remain. |
| 19. |
| Repeat all necessary steps to copy and rotate patterns 18 seven times, with respect to the other angular points of octagon 2, as shown. |
| 20. |
| Circle 1, and patterns 18 and 19, together, make up the final reconstruction. |
| 21. |
| Colour all areas corresponding to standing... |
| 22. |
| ...or to flattened crop, and finish the reconstruction of the 2021 Stanton St Bernard formation. |
| 23. |
| The final result, matched with the aerial image. |
