Shenzhen Gankeng Town Moiré Pattern Dynamic Wall

深圳华侨城甘坑古镇摩尔纹景观墙

该项目位于广东省深圳市华侨城甘坑古镇的门前。该景观墙采用摩尔纹视错觉的原理，将小镇的卡通主题人物融入摩尔纹墙的图案中。实现了运用物理现象让卡通人物“动起来”的视觉效果。

The project is located in front of gankeng Town, Shenzhen, Guangdong Province. The landscape wall adopts the Mohr pattern technology similar to the Anren project, and integrates the cartoon theme characters of the town into the patterns of the Mohr pattern wall. It realizes the visual effect of using physical phenomena to make cartoon characters “move”.

摩尔纹现象常见于数码照相机或者扫描仪等设备上，当感光元件像素的空间频率与影像中条纹的空间频率接近时，可能产生一种新的波浪形的干扰图案。空间频率略有差异的条纹叠加，由于条纹间隔的差异、重合位置会逐渐偏移，继而形成摩尔纹现象。图案由几部分动作组成，根据需要调整条纹状格栅的缝隙与实体的比例，以此生成条状格栅，使得当人眼透过格栅缝隙看到其中一帧动作的图像时，另两帧动作的图像会刚好被遮挡住。进一步以相同比例的条纹格栅为蒙版，将每一帧的图案切割成条状的线图，按照动作顺序拼合图案，就会得到完整的动图图案。当格栅以合适的速度移动，人眼会随着其位置的变化陆续看到动态图像，即会产生图案循环活动起来的错觉。

The moiré effect is commonly found in digital cameras or scanners, etc. When the spatial frequency of the sensor pixels is close to the spatial frequency of the stripes in the image, a new wavy interference patterns may be created. The superposition of stripes with slightly different spatial frequencies, due to the difference in the spacing of the stripes, will gradually shift the coincident position, and then form the moiré effect. The pattern consists of several parts of the action, and the ratio of the slits of the striped grille to the solids is adjusted as needed to generate the striped grille. So that when the human eyes see the one of the frames of action through the grille slits, the other two frames of action will just be obscured. Furthermore, using a striped grille of the same proportion as a mask, cutting each frame into striped drawings, and fitting the patterns together according to the sequence of actions, designer will obtain a complete animation pattern. When the grille moves at the right speed, the human eye will see the dynamic image along with the change of its position, which will create the illusion that the pattern is cyclically active.

由这一原理出发，基于运动错觉现象，利用物体条纹状间隔使图案活动起来，装置需包含外侧条纹状格栅和内侧特殊图案两个基本组成部分，透过移动中的条纹格栅观察图案即会产生动态错觉效果。摩尔纹效应的观察一般通过孔洞板的移动来实现，但依据相对运动原理，通过人的行走来实现人眼与孔洞的相对移动，也会产生摩尔纹现象。本项目位于小镇主入口的步行道路旁，通过过往步行游人与景观墙的相对位置变化，形成摩尔纹动态效果。

Starting from this principle, using the object stripe-like spacing to make the pattern active based on the motion illusion phenomenon, the device should contain the outer stripe grille and the inner side of the special pattern of the two basic components. Through the moving stripe grille, visitors will observe the dynamic illusion effect. The observation of the moiré effect is generally realized by the movement of the hole plate, but according to the principle of relative motion, the relative movement of the human eye and the hole by walking can also produce the moiré effect. The project is located next to the pedestrian road at the main entrance of the town. Through the change of the relative position between the walking tourists and the landscape wall, the dynamic effect of moire pattern is formed.
