是很漂亮。而且又学了一个新单词:
Lenticular is an adjective often relating to lenses. It may refer to:
* Lenticular cloud, a lens-shaped cloud
* Lenticular galaxy, a lens-shaped galaxy
* Lenticular (geology), adjective describing a formation with a lens-
shaped cross-section

Why does this cloud look so strange? Actually, pictured above are several
clouds all stacked up into one striking lenticular cloud. Normally, air
moves much more horizontally than it does vertically. Sometimes, however,
such as when wind comes off of a mountain or a hill, relatively strong
vertical oscillations take place as the air stabilizes. The dry air at the
top of an oscillation may be quite stratified in moisture content, and hence
forms clouds at each layer where the air saturates with m... 阅读全帖

lenticular的风是局部的,就在形成的那个高度有风,并且多半是水平方向,和你所在
的地方有没有风没必然关系
所以登雪山的人见到山上有lenticular,基本是要避免进入的
那里通常是低温+大风+低能见度

他说是clear plastic lenses in any single vision, bifocal, trifocal or

树脂镜片是polycarbonate lense吗?这个不用另外加钱。
度数算高的,而且有闪光。

Mt baldy 这块lenticular单独存在的时间并不长 - 如果没记错,这张应该是在11/06
11AM 至 1PM 照的

来自主题: Outdoors版 - Poor weather this year
It's was 7/6. Anything below 13k was clear. We climbed into the lenticular
cloud but we didn't have a choice. Sunset ridge is just Liberty ridge, it's
nearly impossible to retreat.
Wind was quite strong. From the recorded telemetry data, it was around 30mph
at camp muir, so I think it was 40-50 near summit. I was nearly blown off
my stance several times.

来自主题: DVD版 - Batman Begins DE already OOP
Batman Begins Deluxe Edition is already OOP after only one week. Warner has
encountered problem with the licensing of the comicbook that comes with the
DVD and have pulled it indefinitely. Even if they republish it later, it's not
going to be the same. Especially the Bestbuy's exclusive lenticular cover
version.
I heard the news earlier but thought it's only an temperary thing. Today read
more news and realized it's real. Went to a couple of Bestbuy and magically
found 2 copies left in one store

确实如此!但是如果偏离中心一定角度就看不清了。
NO对眼法AT ALL。这就是我说的,技术进步会逐渐解决的。不过基本原理就还是玩弄
的LENTICULAR原理,当然富士将之提高到了新的水平。

来自主题: Hardware版 - 说两句现在的3D显示
科普一下,呵呵。
其实现在的3D显示都是某种意义上的伪3D,就是利用两个眼镜看到的视差来形成3D的视
幻觉,visual illusion。
那么关键就是要让两个眼睛能看到不同的东西,或者严格的说是同一个东西,但是看上
去在不同的位置来形成这种illusion。
那么怎么让你左眼看到的东西和右眼不一样呢?有几种办法
1.红绿眼镜,这种最老土。左眼看红的,右眼看绿的,原始的3D图像就像套色出了错的
劣质彩色印刷品。这种方法最简单,但是问题也是明显的,彩色还原很糟糕。
2. 偏振眼镜。左眼镜片水平偏振,右眼镜片竖直偏振。现在一般电影院都用这个办法。
3. 高速刷新显示屏加上同步眼镜。现在大部分的3D电视和Nvidia的 3D vision套件就
是这个办法。让电视的刷新频率在120Hz以上,double普通电脑显示器和电视,然后同
步眼镜和电视的显示同步高速切换左右眼,相当于你的左右眼各以每秒60次以上的速度
高速眨眼,分别刊不同的东西。
4. lenticular sheet,这种方法就是在普通显示器前面蒙一层特殊的玻璃(其实是个竖
直排列的柱面微透镜阵列)。利用透镜阵列来形成左右眼不同

accommodation-convergence mismatch
这是基于binocular disparity原理的3D技术无法避免的
如果今后能普及auto-stereoscopic的设备比如lenticular display或者volumetric
display或者全息技术,就能实现真正的3D成像了,不过目前技术还不成熟。
