Analysis of the advantages and disadvantages of water curtain movies
Analysis of the advantages of water curtain movies:
The small water curtains are generally close to 10 meters in length and width, and the area is about 100 square meters. The large lake water curtain can be more than 150 meters long and the height can reach more than 30 meters. The night view effect is more than the urban landmark building. Bright. This water curtain can also be adapted to local conditions, such as the use of local waterfalls. The oversized features of the water curtain are unmatched by other technologies.
The relatively simple pool is flat, with a rectangular vertical plane, an irregular vertical plane, and a 360-degree circular solid. At the beginning of 2011, the circular water curtain film was officially released at the Ocean Park in Hong Kong.
Shocking visual impact
With the super-powerful sound effect, the unpredictable laser beam, like the mirage scene, allows the audience near the scene to experience the mysterious fantasy of the fairyland.
Not only close-up but also far-sighted. Of course, the angle of view is different, and the effect will vary widely. For example, watching at the lake, watching in a nearby high-rise building, in the distance or aerial photography, etc. In short, you can always have a free method.
Analysis of the shortcomings of the water curtain movie:
the cost is too high
A small vertical curtain may cost the least, but the imaging range is too small to make sense. The largest, Singaporean, fixed water curtain landscape film, it is reported that more than 130 million Singapore dollars invested; domestically held, medium-sized water curtain landscape, generally invested in more than 20 million yuan; large, single, laser effect The water curtain show, it is reported that the investment is also more than 10 million yuan. The electricity, water, site, and personnel expenses of the water curtain work are like burning money, and the maintenance cost is very high.
It can only be held in an open area, outdoor area, pool, lake, river, river, seaside, or a square that provides excellent water supply and drainage systems.
Seasons and climate have a great impact. The winter in the north is definitely not good; it is generally chosen in the summer, or in the tropical regions, such as Hong Kong, Macau, Guangzhou, etc., can be performed all year round. Some weather changes can also have unpredictable effects on water curtain movies, such as heavy rain, heavy fog, high winds, thunder and lightning, and hail.
Many hardware devices need to be imported, and there are many technical limitations. Taking the three-dimensional plane water curtain as an example, the power of the ultra-high pressure water pump is limited, and the spraying height from the bottom is limited; the picture is huge, and the dynamic picture such as video is played, and the brightness of the large-scale engineering projector is very high; the super long and wide picture , stitching fusion technology and more.
Due to the reason of the format, the brightness of the light is not high, the water medium is not flat, etc., the water curtain generally only looks at the macro scene, and does not demand detailed performance. To put it simply, just see the painting, and don’t be picky about color, clarity, and delicateness.
