2D icons as well as other objects are well known for their flexibility. This is achieved by the peculiarity of rendering them at different resolutions ideal for various output devices.
2D Icons may embody the next 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 web icons can create the illusion of all 3D characteristics like shadow, reflection or highlighting. The layers should keep the certain hierarchy and order carefully.
2.5D Icons
2Dicons also are known as 2.5D models. This technology offers web site designers ability to work with any layer without touching the others. The best of the prominent graphics editors choose 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 which 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 icons is frequently attained by the special lighting effect. 3D illusion is reached due to the virtual source of light to the left or to the right side and above the users monitor.
