[color=Maroon][size=4]立体视觉和立体画原理
      人有两只眼，两只眼有一定距离，这就造成物体的影象在两眼中有一些差异，见下图，由图可见，由于物体与眼的距离不同，两眼的视角会有所不同，由于视角的不同所看到是影象也会有一些差异，大脑会根据这种差异感觉到立体的景象。[/size][/color]

[/align]

[size=4][color=Maroon]      三维立体画就是利用这个原理，在水平方向生成一系列重复的图案，当这些图案在两只眼中重合时，就看到了立体的影象。参见下图，这是一幅不能再简单的立体画了。图中最上一行圆最远，最下一行圆最近，请注意：最上一行圆之间距离最大，最下一行圆之间距离最小。[/color][/size]

[/align]

[size=4][color=Maroon]      这是怎么发生是呢？让我们再看下图，从图中我们可以看到，重复图案的距离决定了立体影象的远近，生成三维立体画的程序就是根据这个原理，依据三维影象的远近，生成不同距离的重复图案。[/color][/size]
