3D the 2D way - Part 1
Experience 3D by 2D methods (Part 1)
It is often said that if you have a squint, you can't perceive depth. It's not true.
Depth perception is a complex process involving much more information than just the
slightly disparate images of two eyes pointing in the same direction. Here are the other
clues on which depth perception is based:
For example railroad tracks that run parallel, seem to come closer and closer together the farther they are away from you.
If an object is in front of another object (but not completely obscuring it), it will interrupt the contours of the object farthest away from you. The object closest to you will be perceived as being in front of the other object. It is quite obvious that this driver is standing in front of a train.
