2D icons and other objects are well known for their flexibility. This versatility is reached by rendering them at various resolutions suitable 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 for example rotation, scaling or angular position and so on. Meshing simple models you may get more advanced ones.
As a result of layers technique 2D icons can create the illusion of all 3D characteristics such as shadow, reflection or highlighting. The layers really should maintain the definite hierarchy and order carefully. This makes editing 2D icons and related objects easier.
2.5D Icons versus 3D and 2D Icons
2Dicons also are known as 2.5D models. This technology enables site designers to work with any layer with no need of touching the others. The most of the prominent graphics editors prefer this kind of 2D object creation.
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 are not. The featured projection represents both front and side views.
This technology used for designing 2D web icons is often achieved by the special lighting effect. 3D illusion is reached as a result of virtual source of light to the left or to the right side and above the users monitor.
