Yes I would think it difficult to figure out how to outline such a figure on the ground without being able to see it from above- but to do it when taking into account the extreme perspective distortion that results from such a relative low angle would seemingly require a computer to calculate.
Ofcourse it always amazed me how much men accomplished before computers were invented. Many engineering tasks that today would seem impossible without computers was routinely accomplished back in the pre-computer age. I honestly think previous generations had ingenuity and fortitude that we lack today. |
