We see many different objects around us; they are of different shape, size, colour, texture, etc. Not only do we see different objects, we see the objects differently depending on our position and the position of the object. For example: A car looks different when we see it from the front, side and top. A table looks like a rectangle from the top, but from side we can see its legs, and the height of the rectangular top.
