Autostereogram Tutorial Width Of Pattern

• Description: The 3D effects in the previous autostereogram were created by repeating the background pattern (the tiger rider icon) every 140 pixels. The second plane displays shark rider icons every 130 pixels. The highest plane displays tiger icons every 120 pixels. The closer a pattern is packed horizontally, the higher is it lifted from the background plane. This distance is referred to as the 'depth' or z-axis value of a particular pattern in the stereogram.
