埃舍尔的瀑布
ETA:wikipedia
The image depicts a village or village of a small city with an elevated aqueduct and waterwheel as the main feature. The aqueduct begins at the waterwheel and flows behind it. The walls of the aqueduct step downward, suggesting that it slopes downhill. The aqueduct turns sharply three times, first to the left, then straight forward and finally to the left again. The viewer looks down at the scene diagonally, which means that from the viewer's perspective the aqueduct appears to be slanted upward. The viewer is also looking across the scene diagonally from the lower right, which means that from the viewer's perspective the two left-hand turns are directly in line with each other, while the waterwheel, the forward turn and the end of the aqueduct are all in line. The second left-hand turn is supported by pillars from the first, while the other two corners are supported by a tower of pillars that begins at the waterwheel. The water falls off the edge of the aqueduct and over the waterwheel in an infinite cycle. (In his notes on the picture, Escher points out that some water must be periodically added to this apparent perpetual motion machine to compensate for evaporation.) The two support towers continue above the aqueduct and are topped by two compound polyhedra. The one on the left is a compound of three cubes. The one on the right is a stellation of a rhombic dodecahedron (or a compound of three non-regular octahedra).
Below the mill is a garden of bizarre, giant plants. This is actually a magnified view of a cluster of moss and lichen which Escher drew in ink as a study in 1942.
The background seems to be a climbing expanse of terraced farmland.

《瀑布》是埃舍尔在1961年创作的一幅画作,其中描绘的景象看似不可能在现实世界中实现。

然而人类的想象力是无穷的,已经有许多3维模型的实现方案

不过更不可思议的是一位工程师竟然制作出了物理模型!实在是太惊人了!

貌似这图不符合物理定律...只是视觉效果

错觉罢了,只是视觉效果

的确呢,不过要想出如何制造这种错觉已经很不容易了……

此类图看过很多的说……

这种2D的视觉错觉是怎么做成3D的?难道和盗梦空间里的paradox一个原理么?

真像居然是。。。不剧透了,但还是要说这不符合物理定律,难道那玩意儿不是水?

我4、5年前画过类似的图,只是比较简单

恩恩……果然,做成3D果然还是需要……“技巧”的……

额,相当给力呀,非常喜欢这类跟视错觉有关的图,很神秘

我也画过。。。

视觉错觉?

容易被欺骗的眼睛,不猜了,看真相。

看一眼这类图,会不相信自己的眼睛

视觉吧 应嘎

总觉得很违背物理定律,总不能水往高处流吧,看看真相吧……

给水车加动力可以实现,不加动力不行,能量守恒-摩擦损失能量使得水车提上去的水提供的能量小与支持他提水动作的能量,加个动力拿去唬人大约挺有意思,不过水车必须直接提水到最上面,然后流过几圈再冲水车的中上部,真的要做建议用水桶的水车,然后水巢用劈开的竹子,更有东方气息,或者上面加个大风车,有荷兰风味而且还能用风车的动力
