2D icons and other objects are famous for their flexibility. This is achieved by the peculiarity of rendering them at different resolutions suitable for various output devices.
2D Icons may include the following items:
- raster pictures (digital graphics);
- styled text as a typeset for 2D Icons;
- vector models (geometric graphics).
These items can be managed by 2D transformations such as rotation, scaling or angular position etc. Meshing simple models you will get more complex ones.
Due to the layers technique 2D icons can create the illusion of all 3D characteristics like shadow, reflection or highlighting. The layers really should maintain the certain hierarchy and order carefully.
2.5D Icons as the pseudo 3D kind of 2D Icons
2Dicons also are well-known as 2.5D models. This technology allows site designers to work with any layer with no need of touching the others. This type of 2D object creation is liked by the most of the well known graphics editors.
2.5D is a synonym to pseudo 3D and is interpreted as "two-and-a-half-dimensional" graphics. Models created with 2.5D technology look like tridimensional while in fact they are not.
This technology used for designing 2D icons is usually achieved by the special lighting effect. 3D illusion can be reached due to the virtual light source to the left or to the right side and above the users monitor.
