最准确地测量一个目标的距离的方法是运用“视差”，视差是指从不同角度观察一个目标而产生的视角的差异。
The most precise way to measure an object's distance is to use "parallax" - differences in perspective created by viewing an object from different angles.
而后用图像通过滤波器来观察，即所谓的视差屏障（parallaxbarrier），其实主要就是一个划有很多垂直狭缝的观察屏。
The images are then viewed through a kind of filter--called the parallax barrier--that essentially is a screen with a bunch of vertical slits in it.
这项技术近似模拟了观察点相对于粗糙的表面移动时的视差。
This technique approximates the parallax seen when moving the eye relative to an uneven surface.
其特征是再现象视差保持完全，观察者位置不受限制，可以获得准单色象。
Its feature is that reconstructed image is whole parallax, viewer's location is not defined, and quasi-monochromatic image can be obtained.
不一般的视差贴图，要集合良好的演示技术，特定布景，对象纹理和观察视角。
It is one of those techniques that look good in tech demos, papers with specific scenes, textures and viewpoints... but not in general.
