2D web icons are really well known for their flexibility. This is achieved by the peculiarity of 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).
These items can be managed by 2D transformations for example rotation, scaling or angular position etc. Meshing simple models you may get more advanced ones.
Because of 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 as the pseudo 3D sort of 2D Icons
The layered 2Dicons may also be generally known as 2.5D models. This technology enables website designers to work with any layer without the need of touching the others. This kind of 2D object creation is preferred by the most of the leading graphics editors.
2.5D is a synonym to pseudo 3D and is interpreted as "two-and-a-half-dimensional" graphics. Models created with 2.5D technology appear to be tridimensional while in fact they aren't. The featured projection depicts both front and side views.
This technology used for designing 2D 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.
