2D web icons and other objects are well known for their flexibility. This flexibility is achieved by rendering them at various resolutions ideal for various output devices.
2D Icons items:
- raster pictures (digital graphics);
- styled text as a typeset for 2D Icons;
- vector models (geometric graphics).
The above-mentioned items can be managed by 2D transformations such as rotation, scaling or angular position and many others. Meshing basic models you will get more advanced ones.
As a result of 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. This makes editing 2D icons and similar objects easier.
2.5D Icons
2Dicons also are known as 2.5D models. This technology enables web site designers to work with any layer without touching the others. The best of the well known graphics editors prefer this kind of 2D object development.
2.5D is a synonym to pseudo 3D and is interpreted as "two-and-a-half-dimensional" graphics. Models that were created with a help of with 2.5D technology appear to be tridimensional but in fact they aren't.
This technology used for designing 2D web icons is usually attained by the special lighting effect. 3D illusion is reached due to the virtual light source to the left or to the right side and above the users monitor.
