2D web icons as well as other objects are well known for their flexibility. This flexibility is reached 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).
These items can be managed by 2D transformations for example rotation, scaling or angular position etc. Meshing simple models you may get more complex ones.
As a result of layers technique 2D icons can create the illusion of all 3D characteristics like shadow, reflection or highlighting. The layers should keep the definite hierarchy and order carefully. This makes editing 2D icons and similar objects simpler.
2.5D Icons as the pseudo 3D sort of 2D Icons
2Dicons also are well-known as 2.5D models. This technology allows web-site designers to work with any layer without the need of touching the others. This kind of 2D object creation is liked by the most of the well known graphics editors.
2.5D is a synonym to pseudo 3D. It means "two-and-a-half-dimensional" graphics. Models that were developed with a help of with 2.5D technology appear to be tridimensional while in fact they're not. The featured projection represents both front and side views.
This technology used for designing 2D web icons is often attained by the special lighting effect. 3D illusion is achieved due to the virtual light source to the left or to the right side and above the users monitor.
