INTERPOL

Interpol means to fill in the blanks between two points. It's like when you have two dots and you want to draw a line between them, you have to put more dots in between. Interpol is when the computer does this for you by making extra points between the two existing points. It's like using your finger to draw a curved line connecting two dots, only the computer can make more detailed, smoother curves.
