What Is Parallax?
The term Parallax came from a visual effect of 2D scrolling video games that used different background images to create the illusion of depth during game play. This was made for the purpose of making the background move slower than the foreground so as to make it seem far away. It can also be defined as a technique that allows the webpage components to move at different speeds when the user scrolls. This phenomenon creates an appealing visual effect, and this is what people in web designing are incorporating.
How It Works
Parallax is an innovation in web designing, but it had been there for a long time and applied in various applications. Of most importance and easily known is the parallax scrolling that was widely used and it is still used in the gaming applications so as to create a two-dimensional effects of side scrolling. This effect is achieved by the creation of a perspective shift so as to help the observer view the object of the target. The aim of creating a parallax effect is to create a multiple viewpoints from which an object can be observed from a far-flung background.
Methods for Creating Parallax
Some methods can be used to achieve parallax scrolling, these are;
Layers method-this is a method where multiple layers are made to move horizontally or vertically while scrolling at different speed intervals. The layer movement may be user controlled or automated.
Raster- this method involves refreshing pixel and compositing lines in an image arranged in a top to bottom manner. A small delay is introduced between the drawing individual lines so as to create a parallax scrolling.
Sprite- this is done by composting some images into a single one made of pseudo-layers. When you position this at a different angle a single part will be visible, and this will create a 3-dimension effect on the flat images.
The last method is pattern manipulation. It creates parallax by floating multiple screens over repeated backgrounds.
