2D icons and other objects are notable for their flexibility. This versatility is achieved by rendering them at various resolutions ideal for various output devices.
2D Icons may embody the following 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 and so on. Meshing simple models you will get more advanced ones.
Due to the layers technique 2D icons can create the illusion of all 3D characteristics like shadow, reflection or highlighting. The layers really should keep the definite hierarchy and order carefully. This makes modifying 2D icons and similar objects easier.
2.5D Icons vs 3D and 2D Icons
The layered 2Dicons are also known as 2.5D models. This technology gives web designers ability to work with any layer without touching the others. The best of the prominent graphics editors prefer this kind of 2D object creation.
2.5D is a synonym to pseudo 3D. It means "two-and-a-half-dimensional" graphics. Models created with 2.5D technology appear to be tridimensional while in fact they are not.
This technology used for designing 2D icons is usually achieved 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.
