2D icons as well as other objects are well known for their flexibility. This flexibility is reached by rendering them at various resolutions suitable for various output devices.
2D Icons may embody the below 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 such as rotation, scaling or angular position and many others. 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 such as shadow, reflection or highlighting. The layers really should keep the certain hierarchy and order carefully.
2.5D Icons vs 3D and 2D Icons
The layered 2Dicons also are generally known as 2.5D models. This technology provides web designers ability to work with any layer with no need of touching the others. The best of the prominent graphics editors choose this type of 2D object development.
2.5D is a synonym to pseudo 3D. This means "two-and-a-half-dimensional" graphics. Models that were created with a help of 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 is reached due to the virtual source of light to the left or to the right side and above the users monitor.
