2D web icons are actually well known for their flexibility. This versatility is reached by rendering them at various resolutions ideal for various output devices.
2D Icons may include the below items:
- raster pictures (digital graphics);
- styled text as a typeset for 2D Icons;
- vector models (geometric graphics).
All these items can be managed by 2D transformations for example rotation, scaling or angular position etc. Meshing basic models you will get more complex ones.
Because of the layers technique 2D icons can create the illusion of all 3D characteristics such as shadow, reflection or highlighting. The layers should keep the certain hierarchy and order carefully. This makes editing 2D icons and similar objects simpler.
2.5D Icons vs 3D and 2D Icons
The layered 2Dicons are also known as 2.5D models. This technology offers web site designers ability to work with any layer without the need of touching the others. The most of the well known graphics editors choose this type of 2D object creation.
2.5D is a synonym to pseudo 3D. This means "two-and-a-half-dimensional" graphics. Models created with 2.5D technology appear to be tridimensional while in fact they're not. The featured projection represents 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 due to the virtual light source to the left or to the right side and above the users monitor.
