2D web icons and other objects are well known for their flexibility. This is achieved by the peculiarity of rendering them at various resolutions ideal for various output devices.
2D Icons may include the next 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 etc. Meshing basic models you will get more advanced ones.
Due to the layers technique 2D web icons can create the illusion of all 3D characteristics like shadow, reflection or highlighting. The layers should maintain the definite hierarchy and order carefully. This makes editing 2D icons and similar objects easier.
2.5D Icons
2Dicons also are well known as 2.5D models. This technology gives web designers ability to work with any layer without touching the others. The most of the prominent graphics editors choose this type of 2D object development.
2.5D is a synonym to pseudo 3D. It means "two-and-a-half-dimensional" graphics. Models that were built with a help of with 2.5D technology appear to be tridimensional while in fact they are not. The featured projection represents both front and side views.
This technology used for designing 2D web icons is frequently attained by the special lighting effect. 3D illusion is achieved due to the virtual source of light to the left or to the right side and above the users monitor.
