2D web icons and other objects are famous 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).
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.
Due to the layers technique 2D web 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 related objects simpler.
2.5D Icons vs 3D and 2D Icons
The layered 2Dicons also are generally known as 2.5D models. This technology gives web site designers ability to work with any layer without the need of touching the others. The most of the prominent graphics editors prefer this type 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 developed with a help of with 2.5D technology appear to be tridimensional while in fact they're not. The featured projection depicts both front and side views.
This technology used for designing 2D web icons is usually attained by the special lighting effect. 3D illusion can be reached as a result of virtual light source to the left or to the right side and above the users monitor.
